Q: Hello, because no electric video recorder did not manually set, but I would like to look back a few days before the monitor can be transferred out: 1, if the surveillance camera is only access to the monitor, no access to the hard disk video recorder, video images are not stored, you can only see the real-time picture, can not playback.

Q: What is the power of the camera used for monitoring?: If all of the moving point, then the power supply per set of AC24V / 2A, each 50W, 31 * 50 = 1550W, that RVV2 * 0.75 power cord is not enough.
