• Do you need color or black and white cameras? If there are certain situations where it is important to record details such as color of hair, vehicles or clothing, youll need color cameras. Black and white cameras are best if you need higher resolution and generally are less expensive than color. They also are best if you will be using infrared in no light or low light conditions.
• 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.
• Will you be placing the cameras inside or outside? If youll be placing cameras anywhere outside youll need cameras that are built tougher than typical indoor security cameras. Outdoor cameras will be exposed to vandalism and the elements, such as wind and extreme heat or cold. There are many outdoor cameras available that are built to withstand all these outdoor conditions.
The price of security cameras are becoming more affordable so more and more people are enjoying peace of mind with the knowledge that their families and properties are protected 24 hours a day, seven days a week. What You Can Find in a Good Outdoor Camera Security -1

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.
