By Mario Bailey · Data updated June 2026
An idling complaint lives or dies on one clip. Here's the spec checklist derived from the program's evidence requirements, buy against this list, not against marketing copy.

The evidence-grade checklist
- Continuous, unbroken clips of 4+ minutes. Cameras that segment video into 1-minute files are fine only if segments are gapless; verify before relying on it. The complaint needs more than 3 continuous minutes (1 near schools).
- Audio recording, enabled. Engine sound is your proof of idling.
- Resolution that reads plates at distance, in practice 1440p or good 1080p optics; test on a parked car before your first filing.
- Timestamp overlay (GPS optional but valuable).
- Parking/standby mode or easy handheld use, idling happens when you're parked too.
- Simple file export. You'll upload original files to DEP; cameras with painful proprietary apps cost you filings.

Frequently asked questions
Can I just use my phone instead of a dashcam?
Yes, phone video is accepted and many filers start that way. The trade-off is standing in place for 3+ continuous minutes per complaint. A mounted camera captures the same evidence passively.
Does the camera need audio for idling reports?
Strongly recommended. The complaint must show the engine is running; audible engine noise is the most direct proof, alongside visible exhaust. Check that audio recording is enabled, several dashcams ship with it off.
Do I need GPS on the camera?
Not required, but a GPS/timestamp overlay strengthens the where-and-when of your complaint and is hard to dispute later.
