$60 can get you a full 360 degree car cam with G-Sensor and driving alarm warning being too close to another vehicle, is possible?
Here’s how. Buy this similar car camera. Anytek X28 Car DVR Camera Video Recorder WiFi ADAS G-sensor Dash Cam FHD 1080P. Ebay selling it for $15 each, get four, total $60.
Install each one on each side of the vehicle. It has Wifi if you have four android phone you could potential link to each phone for each cam as driving cam so you could potential see all around your car 360 degree. The camera work individually to record and warning alarm.
There you go $60. Easy to install, however probably need to hard wire usb charger to each cam if you don’t want to charge it each time before use 🙂
