Which type of Security Camera should I use?A security camera can come in many different styles including dome, bullet, infrared, c-mount, ptz, and megapixel. The security camera that will work best for your application will depend on several factors such as whether you will use the security cameras inside or out, during the day, nighttime, or both.

The security camera casings are weather resistant and don't require added external protection. Most security cameras have a fixed 4mm lens that allows you to see facial features out to about 35 feet and provides a 70 degree angle of view. This is the widest angle you can have without distorting the picture. Click here for more information about bullet security cameras. .

Unless the infrared security camera is installed flush up to the glass of the housing, the infrared lights can reflect off of the glass of the housing which degrades the image.
The advantage to c-mount security cameras is that the lens can be changed. You'll want a special camera lens if you need to see further than 35 ft. The color c-mount security camera allows you to change lenses on the camera giving you the ability to zoom into a particular area. Varifocal camera lenses allow you to adjust the focus from 5 to 60 mm. These lenses can be used inside only unless you put it in
