I agree. If you need a rearview camera then get another identical dashcam, i.e. an A119 V3. You will immediately know how to use and set up the second unit. Also if the front camera were to fail then you have a backup that you can easily swap to the front!You can of course have a separate rear camera.
Totally agree, however, it's sometimes useful to have evidence of a driver's actions behind. I.e. were they aggressive to other drivers behind you.I can understand you for wanting a #2 camera, but trust me i have been running more cameras in my car for many years now, and those really problematic things / events, in 99% of cases they always manifest on the front camera.
I was stationary in a queue of traffic and the guy behind hit up hard. The police and ambulance were called and the driver admitted to the police that he hit us at 70mph (I'm sure it was more). Fortunately, my wife and I walked away from the collision due to luck but mainly because I have a largish 4x4 (Land Rover Discovery) with a beefed-up towbar, although my wife was on the phone at the time of the collision and sustained permanent nerve damage in her arm and shoulder whilst I sustained a lower back injury. Yes, we were injured but we walked away from the collision and were able to drive the 4x4 home, the other car (a Toyota Yaris) was a writeoff and had no engine bay. In fact, I don't know how the driver and passenger didn't have their legs crushed!And if you get rear ended you dont need to prove that with video it was his fault, your front camera will have you driving along in your lane, so what ever happen back there it surely cant be your fault.
Yes, in the event of an incident it's always good to show a couple of minutes footage before to prove that your driving was beyond blame. However, I wish I'd had a rear dashcam to capture the driver's realisation and reaction just before the impact.But of course it would be nice to have on video to share, but it is not a must, the guy will probably say you swerved or changed lane just in front of him, your front camera footage will prove that was not the case.
