Security cameras come in many different styles including dome, bullet, infrared, IP, and hidden. 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 outdoors, during the day, nighttime, or both. Security cameras come in black and white or color and come with all of the required mounting hardware. The security cameras casings are weather resistant and do not require added external protection. Most security cameras have a fixed 4 mm lens that allows you to see facial features out to about 35 feet and provides a 70" angle of view. Resolution levels for black and white security cameras are about 400 lines, any higher and the benefits are minimal. For color cameras, the higher the resolution the better. Infrared security cameras allow an image to be seen in little or no lighting conditions. Most infrared security cameras are bullet style and can be used inside or outdoors. The cameras have infrared lighting installed around the outer edge of the lens which allows the security camera to see in no light 25 ft or more depending on the camera model - even further with a little bit of light (like street lighting or an outside light.) Dome security cameras provide a different look. If you have any concerns about tampering, check out our vandal proof cameras. Hidden cameras allow you to capture video without anyone knowledge. Most hidden cameras are designed for indoors use.
