Guide to Security Cameras

Traditional fixed security camera

The less expensive option. These security cameras are "fixed" on one area and can be fitted with different lenses for a wide angle of view, an up-close-and-personal shot, or anything in between. Newer surveillance camera models record in full color and in higher resolution. Many security cam models are available, including day/night outdoor security cameras that can automatically adjust to the amount of light available. Some security cameras are known as bullet cameras, owing to their shape and low profile.

I recommend: Sony makes a nice line of fixed security cameras, including day/night functionality, which is great if you need outdoor security cameras.

Dome security camera

A favorite, because the domes 1) can protect the security camera equipment from vandalism and 2) don't let your perpetrators know exactly which way the security camera is pointed. The basic dome surveillance camera is fixed and hidden inside a smoke-colored dome. Look up to the ceiling in any Wal-Mart, and you'll understand how popular this security cam can be.

I recommend: Bosch Security's FlexiDome security cameras can come in B&W or color versions and the dome is designed to be unobtrusive to your business environment.

Pan-tilt-zoom (PTZ) security cameras

Typically housed inside domes, the surveillance camera can rotate about inside. Most PTZ security cameras are used as secondary security cameras and are controlled by your security staff, enabling them to move the security cam and zoom in on incidents of interest, but they can be set on a "patrol" to automatically follow a set path. Expect more cost for PTZ security cameras, plus the additional cost of the control systems and personnel to operate the security cam.

I recommend: Panasonic is one of many manufacturers that make a nice PTZ dome security camera.

Infrared security cameras

These security cameras are for specialty applications, such as watching an area in complete darkness. They use infrared-emitting LEDs to illuminate the scene (the light is invisible to the naked eye), and are often rated for viewing to a particular environment. They're not typical at most businesses, but your needs may not be typical.

I recommend: Canadian company Extreme CCTV makes a nice line of infrared-integrated security cameras.

Network security cameras

Network security cameras function like computers on your business IP network, moving video around just like email. These security cameras reflect a very fast growing market now that many companies are fully wired for Internet access across their premises, and are steadily replacing the traditional security cameras that are connected using coaxial cable or specialty wiring.

I recommend: Axis Communications s considered a market leader in IP video security camera equipment, making a wide variety of styles. Check the network surveillance camera listings on Business.com for more choices.
