Security Camera

Bullet security cameras The smallest of “normal” security cameras, the bullet security cam is easy to install and popular with users who want surveillance to be somewhat covert, or simply don’t want to disrupt architectural factors. A number of bullet cameras also come with “night vision” infrared LEDs to allow the camera to see in the dark – the light is visible to the camera, but not the human eye.

I recommend:  Speco Technologies has a really complete line of bullet security cam models, including black-and-white and color product lines.

Traditional fixed security cameras Fixed indoor security cam systems are mounted in one location and are set to look at a particular area, such as a cash register, an entry door or a stockroom. Larger than bullet cameras, they tend to offer better image quality because they can allow more room for image processing chips inside. Options include standard resolution, high resolution, black-and-white (a.k.a. monochrome) and color. If used indoors, they often don’t need protective housings, but can be mounted in such units if the situation calls for it.

I recommend:  Pelco carries a full line of fixed security cam products. Sony is a big manufacturer here, and also makes the chip (the CCD) that is used in many competitors’ cameras.

Dome security cameras These cameras are covered by a protective dome that helps limit dust and grime. They can be set up as “fixed” – meaning they point in one location — or they can be integrated with motors to pan, tilt and zoom (see action step below).

I recommend:  Bosch Security Systems has a full-line of fixed dome cameras as well as PTZ domes (see links below). Samsung can also show you an impressive line-up in this area.

PTZ (pan, tilt and zoom) security cameras Mounted in central locations, security operators can use a joystick or keyboard to control where a PTZ indoor security camera looks. When shopping for a PTZ security cam, compare how much they can pan, how much they can tilt, and how fast they can move around the scene. Some are slow; some are lightening fast.

I recommend:  Bosch’s BasicDome and AutoDome are two models to check out. Honeywell’s ACUIX PTZ line comes in both indoor and outdoor security camera systems, and the company makes a number of other indoor PTZ domes (including “fixed” domes).

Covert security cameras Covert “spy” security cameras are so small that they can be hidden in a number of common devices, such as clocks. Covert cameras are typically only added to a camera system when investigation of a particular crime is being pursued.

I recommend:  Consumer-grade products like the X10 are small and cheap, but not very covert. Check out sites like Supercircuits and Northern Video for a selection of easily-hidden surveillance cameras.

Network security cameras Network security cameras come in a variety of forms, including those mentioned above, and are solely distinguished by the fact that they communicate their data across a TCP/IP network connection. These systems integrate easily with remote monitoring from your Internet-connected PC.

I recommend:  Axis Communications, Sony, Canon and Panasonic are some of the leaders in this space, which is quickly brimming with more and more manufacturers. Business.com also has a directory page of network security cameras.

Go wireless Wireless indoor security cameras use common frequencies to transmit video over short distances to a receiver. Most need a designated receiver. These typically are of the DIY variety, and aren’t used as permanent solutions. Beware of interference, but these cameras can be applied in a pinch when running cable isn’t practical. Wireless outdoor security cameras are advancing rapidly, as well.

I recommend:  Some of the businesses in this DIY wireless surveillance camera market include Q-See and D-Link.
