2. This section shall only be applicable at intersections in the city of the first class agreed upon by the system administrator and the Secretary of Transportation who shall consider using the automated red light enforcement system at the following intersections:

(b) Owner liability.--For each violation pursuant to this section, the owner of the vehicle shall be liable for the penalty imposed unless the owner is convicted of the same violation under another section of this title or has a defense under subsection (f).

(c) Certificate as evidence.--A certificate, or a facsimile of a certificate, based upon inspection of photographs produced by an automated red light enforcement system and sworn to or affirmed by a police officer employed by the city of the first class shall be prima facie evidence of the facts contained in it. The city must include written documentation that the automated red light enforcement system was operating correctly at the time of the alleged violation. A photograph evidencing a violation of section 3112(a)(3) shall be admissible in any judicial or administrative proceeding to adjudicate the liability for the violation.

(d) Penalty.--

1. The penalty for a violation under subsection (a) shall be a fine of $100 unless a lesser amount is set by ordinance.
2. A fine is not authorized for a violation of this section if any of the following apply:
1. The intersection is being manually controlled.
2. The signal is in the mode described in section 3114 (relating to flashing signals).
3. A fine is not authorized during the first 120 days of operation of the automated system. During the time period under this paragraph, a warning may be sent to the violator.
4. A penalty imposed under this section shall not be deemed a criminal conviction and shall not be made part of the operating record under section 1535 (relating to schedule of convictions and points) of the individual upon whom the penalty is imposed, nor may the imposition of the penalty be subject to merit rating for insurance purposes.
5. No surcharge points may be imposed in the provision of motor vehicle insurance coverage. Fines collected under this section shall not be subject to 42 Pa.C.S. § 3571 (relating to Commonwealth portion of fines, etc.) or 3573 (relating to municipal corporation portion of fines, etc.).

(e) Limitations.--

1. No automated red light enforcement system shall be utilized in such a manner as to take a frontal view photograph of the vehicle as evidence of having committed a violation.
2. Notwithstanding any other provision of law, camera equipment deployed as part of an automated red light enforcement system as provided in this section must be incapable of automated or user-controlled remote intersection surveillance by means of recorded video images. Photographs collected as part of the automated red light enforcement system must be 35-millimeter film only, must only record traffic violations and may not be used for any other surveillance purposes. The restrictions set forth in this paragraph shall not be deemed to preclude a court of competent jurisdiction from issuing an order directing that the information be provided to law enforcement officials if the information is reasonably described and is requested solely in connection with a criminal law enforcement action.
3. Notwithstanding any other provision of law, information prepared under this section and information relating to violations under this section which is kept by the city of the first class, its authorized agents or its employees, including photographs, written records, reports or facsimiles, names, addresses and the number of violations under this section, shall be for the exclusive use of the city, its authorized agents, its employees and law enforcement officials for the purpose of discharging their duties under this section and under any ordinances and resolutions of the city. The information shall not be deemed a public record under the act of June 21, 1957 (P.L.390, No. 212), referred to as the Right-to-Know Law. The information shall not be discoverable by court order or otherwise, nor shall it be offered in evidence in any action or proceeding which is not directly related to a violation of this section or any ordinance or resolution of the city. The restrictions set forth in this paragraph shall not be deemed to preclude a court of competent jurisdiction from issuing an order directing that the information be provided to law enforcement officials if the information is reasonably described and is requested solely in connection with a criminal law enforcement action.
4. Photographic evidence obtained through the use of automated red light enforcement systems deployed as a means of promoting traffic safety in a city of the first class shall be destroyed within one year of final disposition of any recorded event. The city shall file notice with the Department of State that the records have been destroyed in accordance with this section.
5. Notwithstanding any other provision of law, registered vehicle owner information obtained as a result of the operation of an automated red light enforcement system under this section shall not be the property of the manufacturer or vendor of the automated red light enforcement system and may not be used for any purpose other than prescribed in this section.

(f) Defenses.--

1. It shall be a defense to a violation under this section that the person named in the notice of the violation was not operating the vehicle at the time of the violation. The owner may be required to submit evidence that the owner was not the driver at the time of the alleged violation. The city of the first class may not require the owner of the vehicle to disclose the identity of the operator of the vehicle at the time of the violation.
2. If an owner receives a notice of violation pursuant to this section of a time period during which the vehicle was reported to a police department of any state or municipality as having been stolen, it shall be a defense to a violation pursuant to this section that the vehicle has been reported to a police department as stolen prior to the time the violation occurred and had not been recovered prior to that time.
