• 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.
• 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
To make sure that the house is completely safe, the cameras have to be positioned at the right places. People who cannot afford a home camera often use dummy cameras. The dummy security cameras help in alerting the miscreant and prevent crimes like real cameras. However, real cameras provide important evidence at the court when a crime is committed.
There are many ways to keep your house safe from home invasion. You can install outdoor security cameras or dome cameras to see the coming and going of people around you. Before making the purchase, you need to learn more about these security systems and do so by reading up on them.
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.

The camera has a web address, using which you can access its control through the Internet. Other types of wireless cameras include cameras that use television sets or VCRs, to display the images.
