DONT BUY THIS EQUIP! Not compatible with other software. Can't fast forward playback, impossible to find something unless you know the EXACT time it occurred. Zoom in gets grainy. Clips don't save with time stamp unless you tick the box everytime. False motion detection, no motion detection when its relative, playback recordings freeze just at the time when something starts to happen, jumps time... it sucks, don't waste your money on ZMODO! Can' find another app that works with these cameras.
