• 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
• Do you prefer wired or wireless cameras? Hardwired Camera Systems are more reliable than wireless will require that you drill holes into walls to mount cameras and to feed wires through the walls. Wireless Security Camera Systems use radio frequency through the air from the cameras transmitter to a receiver. The receiver picks up the signal and transfers it to a TV or Monitor or Digital Video Recorder. So no wiring is required. Wireless cameras are much easier to install and can be mounted almost anywhere and can be moved around with more ease.
• 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.
