Security cameras are common fixtures at retail outlets and financial institutions. Video surveillance offers an opportunity to catch a crime and the criminal on tape. Recorded video is often used in locating and prosecuting criminals. If video is constantly monitored, video surveillance can stop a crime while it is in progress. There is, however, a lot more to a security camera system than just the cameras we see.

Security System Components

Monitors are a basic element to a security camera system. A monitor, or in some cases monitors, is what is used to view video footage. For small systems, one monitor may be all that is required. If the security system employs the use of multiple cameras, then you will want either a large monitor or several monitors. Analog (VHS) or digital (DVR) recording devices are an important feature of a security camera system. Recording devices can be set to record continuously or only when triggered by an alarm.

Switchers are used to sequence between multiple cameras for viewing on a single screen. When using a switcher, playback of recorded video will have the camera sequencing. A digital quad is what is used to present up to four different camera views on a single screen. Multiplexers will rapidly sequence through multiple cameras while allowing recording of each individual camera for later play back. There are different types of switchers, multiplexers, and quads to choose from. An experienced security company will be able to help you find the right one for your system.

Security camera systems can be viewed and transmitted via computer networks. In order to properly utilize a computer network, the necessary amount of bandwidth must be available. More bandwidth will ensure video feed will be monitored without delay or disruption. Once security footage is processed through a network, it can be viewed from any computer with access to the network. A good option for many businesses is to subscribe to a remote monitoring service, and let them worry about the details.
