[326 P.3d 242] [172 Cal.Rptr.3d 640]
CANTIL-SAKAUYE, C. J.
Defendant was cited for failing to stop at a red traffic light at an intersection located in the City of Inglewood in violation of Vehicle Code section 21453. She was found guilty of the traffic infraction based on evidence of several photographs and a 12-second video. The evidence was generated by an automated traffic enforcement system (ATES), in common parlance referred to as a red light traffic camera. Her conviction was upheld on appeal by both the appellate division of the superior court and the Court of Appeal. We granted review to consider defendant's claim that the trial court improperly admitted the ATES evidence over her objections of inadequate foundation and hearsay. We conclude that the trial court did not abuse its discretion in finding the officer's testimony in this case provided sufficient authentication to admit the ATES evidence and that the ATES evidence was not hearsay. We affirm the judgment of the Court of Appeal.
Statutory authorization of ATES
Local governmental agencies are statutorily authorized to equip a traffic intersection with an ATES, if the system meets certain requirements. (Veh. Code, § 21455.5.) Specifically, the system must be identified by signs visible to approaching traffic that clearly indicate the system's presence and the
traffic signal light governing the intersection must have a minimum yellow light change interval as set by the state Department of Transportation for the designated approach speed. (Veh. Code, § 21455.7.)
A city council or county board of supervisors proposing to install an ATES within its jurisdiction must conduct a public hearing on the proposal prior to entering into a contract for the use of an ATES. (Veh. Code, § 21455.6, subd. (a).) If the proposal is adopted, the local jurisdiction must at each affected intersection " commence a program to issue only warning notices for 30 days" and must " also make a public announcement of the automated traffic enforcement system at least 30 days prior to the commencement of the enforcement program." (Veh. Code, § 21455.5, subd. (b); see People v. Gray (2014) 58 Cal.4th 901, 904 [168 Cal.Rptr.3d 710, 319 P.3d 988].)
" Only a governmental agency, in cooperation with a law enforcement agency, may operate" an ATES. (Veh. Code, § 21455.5, subd. (c).) To operate an ATES, the governmental agency, in cooperation with law [172 Cal.Rptr.3d 641] enforcement, must develop uniform guidelines for screening and issuing violation citations, as well as for processing and storing confidential information. (Veh. Code, § 21455.5, subd. (c)(1).) It must establish procedures to ensure compliance with such guidelines. ( Ibid .) The governmental agency, in cooperation with a law enforcement agency, must also (a) establish guidelines for selection of a location, (b) ensure that the equipment is regularly inspected, (c) certify that the equipment is properly installed and calibrated and is operating properly, (d) regularly inspect and maintain the warning signs, (e) oversee the establishment or change of signal phases and signal timing, and (f) maintain controls necessary to ensure that only those citations that have been reviewed and approved by law enforcement are delivered to violators. ( Id., subd. (c)(2)(A)-(F).)
The statutory scheme allows the governmental agency to contract out these described operational activities or duties " if it maintains overall control and supervision of the system." (Veh. Code, § 21455.5, subd. (d).) But this is subject to an important qualification. The governmental agency may not contract out to " the manufacturer or supplier of the automated traffic enforcement [326 P.3d 243] system" certain of the described duties. ( Ibid. [providing that the activities specified in Veh. Code, § 21455.5, subd. (c)(1) & (2)(A), (D)-(F) may not be contracted out to the ATES manufacturer or supplier].) The only duties that may be contracted out to the ATES manufacturer or supplier are the activities of " [e]nsuring that the equipment is regularly inspected" and " [c]ertifying that the equipment is properly installed and calibrated, and is operating properly." (Veh. Code, § 21455.5, subds. (c)(2)(B), (C), (d).)
A contract between a governmental agency and an ATES manufacturer or supplier entered into, renewed, extended or amended on or after January 1,
2004, is statutorily prohibited from including a " provision for the payment or compensation to the manufacturer or supplier based on the number of citations generated, or as a percentage of the revenue generated, as a result of the use of the equipment." (Veh. Code, § 21455.5, subd. (h)(1); see id., former subd. (g), as amended by Stats. 2003, ch. 511, § 1, p. 3923 [applicable at the time of defendant's citation].)
The evidence submitted in this case
A notice to appear was issued to defendant pursuant to the City of Inglewood's implementation of the automated traffic enforcement statutes we have described. (Veh. Code, § § 21455.5-21455.7.) The citation alleged that on March 13, 2009, defendant failed to stop at a red traffic light located at the intersection of Centinela Avenue and Beach Avenue in the City of Inglewood (Inglewood). Defendant entered a plea of not guilty.
At the court trial held before a traffic commissioner, only one witness testified. Dean Young, an investigator with the Inglewood Police Department, testified that he was assigned to the traffic division in red light camera enforcement, and had more than six years of experience in that assignment. Young testified that defendant's citation was the result of the red light camera program first implemented by Inglewood in 2003.
Young testified that Inglewood's ATES was operated by the police department, but was maintained by Redflex Traffic Systems, Inc. (Redflex). Based on his experience and the knowledge that he acquired from city engineers regarding how the traffic signals and system work and from Redflex regarding how the ATES works, Young testified that the computer-based [172 Cal.Rptr.3d 642] digital camera system operates " independently" and records events occurring within an intersection after the traffic signal has turned red. Young stated that the ATES information is stored as it is " reported" on the hard disc of a computer at the scene. According to Young, Redflex technicians retrieve that computerized information periodically throughout the day through an Internet connection. A police officer then reviews all photographs before a citation is printed or mailed.
Young explained the photos and video images that are recorded and produced by the ATES as follows. There are three photographs taken, plus a 12-second video. The first photograph taken by the ATES camera, referred to as a " previolation" photograph, shows the vehicle at or before the crosswalk or limit line for the intersection with the traffic signal shown in the background during its red phase. The second photograph, referred to as a " postviolation" photograph, shows the vehicle within the intersection either in the process of making a right turn or going straight through the intersection.
The third photograph shows the vehicle's license plate. A data bar is imprinted on all the photographs by the ATES to show the date, time, location, and how long the light had been red at the time of the photograph. The 12-second video shows the approach and progression of the vehicle through the intersection.
Young testified, based on the ATES evidence, that defendant's violation occurred at the intersection of Centinela Avenue and Beach Avenue on Friday, March 13, 2009. It involved a " straight through movement" by defendant. Defendant objected that the photographs did not establish that she was the driver of the vehicle depicted in the photographs because the right eye and part of the forehead of the person shown in the photograph was obscured. The trial court stated that it was satisfied that the photograph depicted defendant as the driver.
[326 P.3d 244] Defendant then objected to Young's testimony on the grounds of lack of foundation and hearsay. The trial court overruled the objections after defendant examined Young on voir dire. Young proceeded to testify that the data bar printed on the previolation photograph of defendant's vehicle showed the traffic light had been red for 0.27 seconds and that defendant's vehicle's approach speed was 53 miles per hour at the time the photograph was taken. According to Young, in the postviolation photograph taken 0.66 second later, defendant's vehicle was shown in the intersection while the signal light remained in the red light phase. Young testified that the 12-second video of defendant's vehicle crossing the intersection began with the signal light in its green phase and showed the transitioning of the light phases, including a four-second yellow light.
Defendant challenged Young's characterization of the yellow light interval as being four seconds. Asked by the court to lay a foundation for his opinion regarding the yellow light interval, Young testified that he visually inspected the traffic signal at this intersection and each of the other camera-enforced intersections on a monthly basis to ensure that the yellow phase timing complies with the minimum guidelines established by California's Department of Transportation. According to Young, on February 16, 2009, and March 16, 2009, he conducted timing checks of the signal at this intersection, which showed averages of 4.11 and 4.03 seconds, respectively. He testified that these test results were well above the 3.9 seconds established by the Department of Transportation for a 40-mile-an-hour zone.
[172 Cal.Rptr.3d 643] Based on this evidence, the trial court found beyond a reasonable doubt that defendant was guilty of failing to stop at a red signal light and imposed a fine of $ 436.
Photographs and video recordings with imprinted data are writings as defined by the Evidence Code. (Evid. Code, § 250.)  To be admissible in evidence, a writing must be relevant and authenticated. (§ § 350, 1401.) The proffered evidence must be an original writing or otherwise admissible secondary evidence of the writing's content. (§ § 1520, 1521.) And it must not be subject to any exclusionary rule. (See, e.g., § 1200.)
Defendant contends the trial court erred in admitting the ATES evidence in this case because the prosecution failed to provide the foundational testimony necessary to authenticate it and because the evidence included inadmissible hearsay. We review claims regarding a trial court's ruling on the admissibility of evidence for abuse of discretion. ( People v. Alvarez (1996) 14 Cal.4th 155, 203, 207 [58 Cal.Rptr.2d 385, 926 P.2d 365]; People v. Lucas (1995) 12 Cal.4th 415, 466 [48 Cal.Rptr.2d 525, 907 P.2d 373].) Specifically, we will not disturb the trial court's ruling " except on a showing the trial court exercised its discretion in an arbitrary, capricious, or patently absurd manner that resulted in a manifest miscarriage of justice." ( People v. Rodriguez (1999) 20 Cal.4th 1, 9-10 [82 Cal.Rptr.2d 413, 971 P.2d 618].) Applying this standard, we conclude that the trial court did not err in admitting the ATES evidence over defendant's objections.
The ATES evidence was adequately authenticated
Defendant argues that the trial court erred in overruling her objection to the ATES evidence on the basis of inadequate foundation. We disagree.
Authentication of a writing, including a photograph, is required before it may be admitted in evidence. (§ § 250, 1401.) Authentication is to be determined by the trial court as a preliminary fact (§ 403, subd. (a)(3)) and is statutorily defined as " the introduction of evidence sufficient to sustain a finding that it is the writing that the proponent of the evidence claims it is" or " the establishment of such facts by any other means provided by law" (§ 1400). The statutory definition ties authentication to relevance. As explained by the California Law Revision Commission's comment to section 1400, " [b]efore any tangible object may be admitted into evidence, the party seeking to [326 P.3d 245] introduce the object must make a preliminary showing that the object is in some way relevant to the issues to be decided in the action. When the object sought to be introduced is a writing, this preliminary showing of relevancy usually entails some proof that the writing is authentic-- i.e., that the writing was made or signed by its purported maker. Hence, this showing
is normally referred to as 'authentication' of the writing." (Cal. Law Revision Com. com., 29B pt. 4 West's Ann. Evid. Code (1995 ed.) foll. § 1400, p. 440.) Authentication is essentially a subset of relevance. (See Lorraine v. Markel American Ins. Co. (D.Md. 2007) 241 F.R.D. 534, 539 ( Lorraine ); 2 Broun, McCormick on Evidence (7th ed. 2013) § 212, p. 5 (McCormick).)
As with other writings, the proof that is necessary to authenticate a photograph or video recording varies with the nature of the evidence that the photograph or video recording is being offered to prove and with the degree of possibility of [172 Cal.Rptr.3d 644] error. (Annot., Authentication or verification of photograph as basis for introduction in evidence (1950) 9 A.L.R.2d 899, 900.) The first step is to determine the purpose for which the evidence is being offered. The purpose of the evidence will determine what must be shown for authentication, which may vary from case to case. (2 McCormick, supra, § 221, pp. 82-83.) The foundation requires that there be sufficient evidence for a trier of fact to find that the writing is what it purports to be, i.e., that it is genuine for the purpose offered. ( People v. Valdez (2011) 201 Cal.App.4th 1429, 1434-1435 [135 Cal.Rptr.3d 628] ( Valdez ).) Essentially, what is necessary is a prima facie case. " As long as the evidence would support a finding of authenticity, the writing is admissible. The fact conflicting inferences can be drawn regarding authenticity goes to the document's weight as evidence, not its admissibility." ( Jazayeri v. Mao (2009) 174 Cal.App.4th 301, 321 [94 Cal.Rptr.3d 198].)
Here the ATES evidence was offered to show what occurred at a particular intersection in Inglewood on a particular date and time when the traffic signal at the intersection was in its red phase. The ATES evidence was offered as substantive proof of defendant's violation, not as demonstrative evidence supporting the testimony of a percipient witness to her alleged violation. We have long approved the substantive use of photographs as essentially a " silent witness" to the content of the photographs. ( People v. Bowley (1963) 59 Cal.2d 855, 860 [31 Cal.Rptr. 471, 382 P.2d 591].) As we stated in Bowley, " [t]o hold otherwise would illogically limit the use of a device whose memory is without question more accurate and reliable than that of a human witness. It would exclude from evidence the chance picture of a crowd which on close examination shows the commission of a crime that was not seen by the photographer at the time. It would exclude from evidence pictures taken with a telescopic lens. It would exclude from evidence pictures taken by a camera set to go off when a building's door is opened at night." ( Id., at p. 861.)
A photograph or video recording is typically authenticated by showing it is a fair and accurate representation of the scene depicted. ( People v. Gonzalez (2006) 38 Cal.4th 932, 952 [44 Cal.Rptr.3d 237, 135 P.3d 649];
People v. Cheary (1957) 48 Cal.2d 301, 311-312 [309 P.2d 431].) This foundation may, but need not be, supplied by the person taking the photograph or by a person who witnessed the event being recorded. ( People v. Mehaffey (1948) 32 Cal.2d 535, 555 [197 P.2d 12]; People v. Doggett (1948) 83 Cal.App.2d 405, 409 [188 P.2d 792]; 2 Witkin, Cal. Evidence (5th ed. 2012) Documentary Evidence, § 7, pp. 154-156 (Witkin).) It may be supplied by other witness testimony, circumstantial evidence, content and location. ( Valdez, supra, 201 Cal.App.4th at p. 1435; People v. Gibson (2001) 90 Cal.App.4th 371, 383 [108 Cal.Rptr.2d 809]; see People v. Skiles (2011) 51 Cal.4th 1178, 1187 [126 Cal.Rptr.3d 456, 253 P.3d 546]; 2 Witkin, supra, at pp. 154-155.) Authentication also may be established " by any other means provided by law" (§ 1400), including a statutory presumption. (Cal. Law Revision Com. com., supra, foll. § 1400, p. 440 [" The requisite preliminary showing may also be supplied by a presumption." ].)
[326 P.3d 246] The People argue that sections 1552 and 1553 provide such a presumption of authenticity for ATES images and data. The People are correct that sections 1552 and 1553 are applicable here. These statutes' presumptions partly, but not completely, supply the foundation for admission of ATES evidence.
[172 Cal.Rptr.3d 645] Subdivision (a) of section 1553 provides, as pertinent here, that " [a] printed representation of images stored on a video or digital medium is presumed to be an accurate representation of the images it purports to represent. ... If a party to an action introduces evidence that a printed representation of images stored on a video or digital medium is inaccurate or unreliable, the party introducing the printed representation into evidence has the burden of proving, by a preponderance of evidence, that the printed representation is an accurate representation of the existence and content of the images that it purports to represent." Subdivision (a) of section 1552 provides a similar presumption for " [a] printed representation of computer information or a computer program." In 2012, the Legislature added a subdivision (b) to both sections to expressly clarify the applicability of the statutes to printed representations of video or photographic images stored by an ATES and printed representations of computer-generated information stored by an ATES. (§ § 1552, subd. (b) [" Subdivision (a) applies to the printed representation of computer-generated information stored by an automated traffic enforcement system." ], 1553, subd. (b) [" Subdivision (a) applies to the printed representation of video or photographic images stored by an automated traffic enforcement system." ]; Sen. Rules Com., Off. of Sen. Floor Analyses, 3d reading analysis of Sen. Bill No. 1303 (2011-2012 Reg. Sess.) as amended
May 29, 2012, p. 4, par. 8; Assem. Com. on Judiciary, Analysis of Sen. Bill No. 1303 (2011-2012 Reg. Sess.) as amended June 26, 2012, p. 14.) 
Sections 1552 and 1553 were added to the Evidence Code as part of the 1998 legislation that repealed the best evidence rule (former § 1500) and adopted the secondary evidence rule (§ § 1520-1523; Stats. 1998, ch. 100, § § 4, 5, pp. 634-635.)  Under the secondary evidence rule, the content of a writing may now be proved either " by an otherwise admissible original" (§ 1520) or by " otherwise admissible secondary evidence" (§ 1521, subd. (a); see People v. Skiles, supra, 51 Cal.4th at p. 1187). Sections 1552 and 1553 permit the writings that they describe to be introduced as secondary evidence. Thus, the presumptions in sections 1552 and 1553 eliminate the basis for any objection that a printed version of the described writings is not the " original" writing.
Because sections 1552 and 1553 provide a presumption for both " the existence and content" of computer information and digital images that the printed versions purport to represent (§ § 1552, subd. (a), 1553, subd. (a)), the presumptions operate to establish, at least preliminarily, that errors in content have not been introduced in the course of printing the images and accompanying [172 Cal.Rptr.3d 646] data. As the court in People v. Hawkins (2002) 98 Cal.App.4th 1428, 1450 [121 Cal.Rptr.2d 627] ( Hawkins ) explained, the presumptions essentially operate to establish that " a computer's print function has worked properly." As applicable here, the presumptions provided by sections 1552 and 1553 support a finding, in the absence of contrary evidence, that the printed versions of ATES images and data [326 P.3d 247] are accurate representations of the images and data stored in the ATES equipment.
We reject defendant's contention that application of these presumptions violates her right to constitutional due process as described in Western & A. R. Co. v. Henderson (1929) 279 U.S. 639, 642-644 [73 L.Ed. 884, 49 S.Ct. 445]. The court in Henderson held invalid a statutory rebuttable presumption in a civil case for lack of a rational connection between the
ultimate fact presumed and the fact actually placed in evidence. (See Lavine v. Milne (1976) 424 U.S. 577, 585 [47 L.Ed.2d 249, 96 S.Ct. 1010].) In the criminal context, however, a due process challenge to an evidentiary presumption requires us to distinguish between mandatory presumptions, which either can be conclusive or rebuttable, and permissive inferences. ( Francis v. Franklin (1985) 471 U.S. 307, 313-315 [85 L.Ed.2d 344, 105 S.Ct. 1965].) Mandatory presumptions will violate due process if they relieve the prosecution of the burden of persuasion on an element of the offense. ( Patterson v. New York (1977) 432 U.S. 197, 215 [53 L.Ed.2d 281, 97 S.Ct. 2319]; see Sandstrom v. Montana (1979) 442 U.S. 510, 520-524 [61 L.Ed.2d 39, 99 S.Ct. 2450].) Permissive inferences violate due process only if the permissive inference is irrational. ( Francis, supra, at pp. 314-315; Ulster County Court v. Allen (1979) 442 U.S. 140, 157-163, 60 L.Ed.2d 777, 99 S.Ct. 2213; People v. Moore (2011) 51 Cal.4th 1104, 1131-1132 [127 Cal.Rptr.3d 2, 253 P.3d 1153].) The rebuttable presumptions set forth in sections 1552 and 1553 affect the burden of producing evidence regarding a preliminary fact necessary for the admission of evidence. As their presumptions affect the admissibility of the described writings when offered by any party, but do not require any weight to be given to the evidence if admitted, sections 1552 and 1553 do not reduce the prosecution's burden of proof to show defendant's violation beyond a reasonable doubt. They establish only permissive inferences, which, being logically grounded on advances in technology, are not irrational. ( Francis, supra, at pp. 314-315; Moore, supra, at p. 1132.)  Contrary to defendant's argument, these presumptions do not deny defendant a fair opportunity to rebut the presumed accuracy or reliability of the offered evidence. ( Henderson, supra, 279 U.S. at p. 642.) 
[172 Cal.Rptr.3d 647] Although we reject defendant's constitutional challenge, it is important to recognize that the presumptions in sections 1552 and 1553 do not in themselves fully supply the necessary foundation for admission of ATES evidence. The secondary evidence rule does not " excuse compliance with Section 1401 (authentication)." (§ 1521, subd. (c).) " [T]o be 'otherwise admissible,' secondary evidence must be authenticated." ( People v. Skiles, supra, 51 Cal.4th at p. 1187; see § 1401, subd. (b) [326 P.3d 248] [" Authentication of a writing is required before secondary evidence of its content may be received in evidence." ].)
Here, Young's testimony was adequate to show that the ATES photographs at issue were from Inglewood's ATES equipment located at the corner of Centinela and Beach Avenues. From his explanation regarding the independent operation of the ATES camera system, it can be reasonably inferred that the ATES system automatically and contemporaneously recorded the images of the intersection and the data imprinted on the photographs when it was triggered. Young was not asked anything about the city's or the police department's records or supervision of Redflex's maintenance or certification of the equipment.  Defendant does not argue that Young's testimony was insufficient to demonstrate that the evidence was properly received in the normal course and manner of Inglewood's operation of its ATES program. Finally, we note that the content of the photographs themselves may be considered and here the content supplied further support for a finding that the images were genuine.  Indeed, at oral argument, defendant's [172 Cal.Rptr.3d 648] counsel conceded that the ATES photographs in this case actually depicted
his client in the intersection. Accordingly, we conclude that, in conjunction with the operation of the presumptions of sections 1552 and 1553, sufficient evidence was submitted to the court to sustain a finding (§ 403, subd. (a)(3)) that the ATES evidence " is the writing that the [prosecution] claim[ed] it is" (§ 1400) and the trial court properly exercised its discretion to admit the evidence.
Defendant claims, however, that in this case involving digital images it was necessary for the prosecution as part of its foundational showing to additionally present the testimony of a Redflex technician regarding the operation and maintenance of the system that generated the ATES evidence because digital images are more readily and inexpensively subject to manipulation, and yet at the same time, such manipulations are more difficult to detect, compared with an analog alteration. We disagree that the testimony of a Redflex technician or other witness with special expertise in the operation and maintenance of the ATES computers was required as a prerequisite for authentication of the ATES evidence.
Contrary to defendant's assertion, the record contains no evidence that the ATES evidence was materially altered, enhanced, edited or otherwise changed; rather it consisted of entirely automatically produced photos and video and contemporaneously recorded data. No elaborate showing of accuracy is required. (See 2 McCormick, supra, § 227, p. 111 [accuracy of an individual computer's basic operations will not be scrutinized unless specifically challenged, and even perceived errors go to the weight of the evidence, not its admissibility].) We decline to require a greater showing of authentication for the admissibility of digital images merely because in theory they can be manipulated. (See Owens v. State (2005) 363 Ark. 413 [214 [326 P.3d 249] S.W.3d 849, 854] [refusal to impose a higher burden of proof for admissibility of still photographs taken from a store surveillance camera's videotape merely because digital images are easier to manipulate].) We have not required testimony regarding the " 'acceptability, accuracy, maintenance, and reliability of ... computer hardware and software' " in similar situations. ( People v. Martinez (2000) 22 Cal.4th 106, 132 [91 Cal.Rptr.2d 687, 990 P.2d 563], quoting People v. Lugashi (1988) 205 Cal.App.3d 632, 642 [252 Cal.Rptr. 434]; accord, People v. Nazary (2010) 191 Cal.App.4th 727, 755 [120 Cal.Rptr.3d 143].) The standard foundational showing for authentication of a photograph, video, or other writing will suffice for ATES images and data information. 
[172 Cal.Rptr.3d 649] We conclude that the trial court did not abuse its discretion in overruling defendant's objection of lack of foundation.
ATES evidence does not constitute hearsay
Defendant contends that some of the data bar information imprinted on the ATES photographs constitutes hearsay that does not come within either the business records or public records exception to the hearsay rule. She asserts that the trial court erred in overruling her objection raising that ground for exclusion of the evidence. We disagree.
As we have explained, the evidence before the trial court reflects that the digital photographs were taken automatically by the ATES. Admittedly, the ATES must be programmed to activate when certain criteria are met, but it is undisputed that at the time any images are captured by the digital image sensors in the ATES cameras, there is no Inglewood city employee, law enforcement officer or Redflex technician present watching the intersection and deciding to take the photographs and video.  The ATES routinely monitors the intersection without human ...
