1, the camera generally talked about the camera, it is natural to think of home cameras. In fact, surveillance cameras and home cameras are many different, first of all fundamentally design standards are different, one for industrial applications and design, one for home use and design, so they work in a long time, the use of the environment The volume is small, the monitoring machine with small size, and the home machine because all the control parts and tape all installed in the same chassis, so the volume to be much larger, and must be on-site manual control, can not achieve remote remote control ; In the key resolution, the home machine is generally about 300 lines in the horizontal, and monitoring machine for the blackboard on the blackboard, the horizontal resolution should be more than 400 lines.
