Here’s what the remote control does. It’s a great add-on that you can place somewhere nearby instead of reaching up to the A129 to press on the emergency record button.


Test setup

Initially, I set up both cams at the front windscreen but later changed it to front and rear windscreen as I wanted to record the rear using the IR cam. I’m using the 128GB Transcend High Endurance microSD for the recordings.


Below is recorded in 1920×1080 30fps with an overall bit rate of 17.1 Mb/s with WDR on and without the CPL filter.

Final thoughts
The A129 Duo IR is a great option for those driving a taxi, Uber, etc.

Using the IR cam as a rear cam, the Auto mode will have the infrared LED lights reflecting on the windscreen with a purple hue in the center. Better to use the IR Color mode if want to use the IR cam as a rear cam.

Found a bug while changing the IR mode from Mono/IR Color mode to Auto mode, it will remain in Mono/IR Color mode until the A129 has restarted then will be in Auto mode.
