How is the Frame Rate related to Picture Quality?

• Quality can refer to both how detailed the image is and how fast the frame rate is. Frame rate is simply a measure of how many individual pictures make up the video. "Full motion", what you see on television and on VHS tapes, is 30 frames per second, or fps. Most often, security systems record at slower rates, which result in more jerky-looking images but saves tape or hard drive space, allowing longer periods of time to be recorded

Camera's Format:

• Camera formats are measured in inches: most surveillance cameras fall between 1/4" and 1". This refers to the usable image size created inside the camera. For most security systems, a small size is fine - 1/4" or 1/3" surveillance cameras dominate CCTV sales. Larger formats do not necessarily result in better images, but can be advantageous in dimly lit situations since they are able to gather more light

Focal Lens important:

• If you're looking for a security camera for the office or warehouse and you want to see as much as you can, you should look for a 2.8 or 4mm lens (provides a wide, somewhat distant view). If you need to observe a limited area, such as an entrance, you should choose an 8mm lense (provides a narrow view and objects are closer). In other words, the smaller the focal length number, the wider the field of view. To get the most flexibility in choosing the best field of view, consider a varifocal lens.

Varifocal Lens:

• The varifocal lens is ideal in situations where the security camera surveys a distant point. One can adjust the zoom and focus of these lenses, either manually or automatically. This is sometimes referred to as "manual zoom" lens

CCD:

• It is analog technology. The CCD camera has a little bit higher resolution than CMOS. The camera also functions better in low light. A CCD
