The A3 has the same cameras, screen and recording as the A5: a 2K (2560 × 1440) front camera at 25 fps with a 140° view, a 720p rear camera at 25 fps with a 130° view, and a 3-inch IPS screen (640 × 360). The two models differ in their housing. Video is stored in H.264 on a microSD card of up to 512 GB.

What the A3 does

Shows both views on the unit. An installer can check the front and rear angles on the screen, and a driver can review a clip in the vehicle straight after an incident.
Tracks with route playback. GPS and BeiDou positions are linked to the footage in the Traqcare app and web platform, so a route can be replayed with its video.
Carries voice. A built-in microphone and speaker give two-way voice with dispatch over 4G.
Watches while parked. With the ignition off, 24-hour parking monitoring records when it detects an impact or another abnormal event, and the 3-axis G-sensor locks the clip.
Keeps about 110 hours. With both cameras recording at the standard bitrates, a 512 GB card holds about 110 hours before the oldest file is overwritten.
Updates remotely. Firmware is updated from the card or over the air.

Installation

Power is 5 V through the Type-C port. The supplied cable takes 12–24 V from the vehicle, and an ACC line follows the ignition.
Mount behind the rear-view mirror so the screen is visible without blocking the driver's view, and run the rear camera cable along the headlining.
Connect the external GPS antenna, fit a 4G data SIM and a microSD card of Class 10 or faster, and pair the device in the app.
4G bands: FDD B1/3/5/8 and TDD B38/39/40/41. Check that your carrier uses them.
Seven keys and a reset button operate the menus.

The A3 has no ADAS and no driver monitoring; for those, see the D9.

A3 questions

What is the difference between the A3 and the A5?

The housing. Both have the same 2K front and 720p rear cameras, 3-inch IPS screen, 4G, GPS and 512 GB microSD support. Ask us for the dimensions of each if mounting space is tight.

How many hours of video does the A3 keep?

About 110 hours on a 512 GB card with both cameras recording, at the standard 7 Mbps for 2K plus 3 Mbps for 720p. Loop recording then overwrites the oldest file.

Does the A3 have ADAS or driver monitoring?

No. The A3 has no AI safety functions. For ADAS and DMS, choose the [D9](/product/d9-dual-lens-dashcam/).

Does the A3 record while the vehicle is parked?

Yes. With the ignition off, 24-hour parking monitoring records when it detects an impact or another abnormal event, and the G-sensor locks the clip. The camera draws on the vehicle battery to do this, so hardwire it with a low-voltage cutoff.
