dash cam

This is what I bought, total cost for camera and micro SD card was under $50 https://smile.amazon.com/Recorder-Wireless-Dashboard-Recording-G-sensor/dp/B06Y3ZFY2P/ref=sr_1_6?ie=UTF8&qid=1498183630 works as a wifi accesspoint and displays via an ap on any smartphone. Only downside is it can default to the off position if connected to a switched power connection, or if vehicle batteries are disconnected for engine maintenance, storage, etc.
