• 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
The first security camera was a c-mount security camera, and they were first introduced in the 1970. Perhaps it was the fact that fashion was not at its high that these boxy, bulky security cameras look the way that they do, but it had more to do with the technological limitations of the time. As camera technology was in its infancy, chips sets and circuit boards were much larger than today, which rather restricted security cameras to the c-mount camera style. For many years, c-mount camera design defined the security camera industry, but now the most common shape that most people think of when mentioning a security camera is the bullet camera.
• 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.
