Police cams activate intelligently without officer intervention. The Axon Fleet 3 syncs with:

• Vehicle systems: Starts recording when lights/sirens activate or during sudden braking.
• Body cameras: Links to an officer’s Axon Body 3 to create synchronized multi-angle evidence.
• Dispatch software: Tags footage with CAD (Computer-Aided Dispatch) event numbers for easy retrieval.

This automation eliminates human error—critical when officers are focused on emergencies.

3. Secure Evidence Management

Chain-of-custody protocols are non-negotiable. Police dash cams use:

• Encrypted storage: AES-256 encryption prevents tampering (e.g., WatchGuard’s “Locked File” feature).
• Audit trails: Tracks every access attempt, ensuring admissibility in court.
• Cloud backup: Axon Evidence.com automatically uploads footage, preventing loss if the cruiser is damaged.

A 2022 study by the National Institute of Justice found departments using these systems reduced evidence disputes by 43%.

4. Advanced Night Vision and Low-Light Clarity

Over 60% of police shootings occur in low light (FBI UCR data). Models like the Vista X3 use:

• Starlight sensors: Capture color video in near-total darkness (0.001 lux sensitivity).
• IR illuminators: Built-in infrared LEDs illuminate faces/plates without blinding drivers.

In a real-world test by the LAPD, these features improved suspect identification accuracy by 58% compared to standard cams.

These features explain why departments rarely repurpose consumer dash cams—compromising on any of these could risk cases being thrown out or officers’ safety.

How Police Departments Select and Implement Dash Cams

Choosing the right dash cam system involves more than comparing specs—it requires aligning technology with departmental policies, budgets, and legal requirements. Here’s a detailed look at the selection criteria and deployment process used by law enforcement agencies nationwide.
