4 Channel 720P Car DVR AHD Video/Audio SD Card Recorder (Support up to 128GB) with VGA Port for Bus Truck Trailer Van Car Vehicle Surveillance

Overall a good buy... Thankfully the menu's are written in English. I bought a few other brands and they are pretty much useless if the menus are in Chinese....2 months old at this point and still working as it should!

If you can get it working, it's a pretty good device. The manual is minimally useful. The English on screen menu is confusing enough, but if you have the bad fortune of a spontaneous switch to Chinese... good luck. The power supply is wonky. Power, ground, acc, but the acc is useless because once you get the power and ground connected it's in an always on state. The acc wire does nothing. I put the power wire on a switch... so ok. If you have a bit of familiarity with auto electric and a lot of patience, it's pretty good when you get it going.

Video is stored but inaccessible unless you download their app. Being from China, I am reluctant to download and have the video or metadata pushed overseas. The SD card becomes inoperable thereafter.

Works good with my car stereo. Can review videos without out taking card out
