• DVR. This is a hard drive that allows you to record and playback the video feed from the security system. When the memory becomes full, the new video signal will then overwrite the oldest one. There are some systems that have memories large enough to record 150 days worth of footage.
Every c-mount security camera has a varying ability to see in the dark. To know how well the camera works in low lighting conditions, you will need to compare its lux rating. A lower lux rating means that the camera will be able to operate better in lower light. Because c-mount cameras can deliver color video in poor lighting conditions, c-mount cameras are especially valued in crime-fighting and government operations. Lower lux ratings usually correlate with more expensive machines.
• Motion Sensing. Some cameras are equipped with motion sensors. The security system turns on and begins recording when the motion sensors are activated. This will come in handy when you dont have a DVR. Types of Outdoor Surveillance Cameras
