This is a nice, compact wide-angle dash-camera. It records continually in a loop and you can freeze a recording on your SDcard by pressing a button for evidence when necessary. It also has a sensor that will start recording when it detects a bump to the car. It starts recording automatically when you turn on the ignition (assuming you have a lighter that is controlled by your ignition key). It records in 720p resolution. The lens will record 120 degrees. It requires a Micro-SDcard (TF card), not included, and supports up to 32GB.
I purchased it for my bother's vehicle. I made photos while testing the unit. This will work very well for him.
