Understanding Security Camera Requirements

Understanding security camera requirements depends on the user's reasons for deploying the devices. Home or business  owners have different reason for installing cameras and must choose between a wired or wireless installation. Advances in the security industry have made security cameras more affordable and easier to install. Now, homeowners, business owners and other users can find a set-up ranging from a single security camera to a more complicated multi-camera system


Purpose
Some homeowners used a simple one-camera system. Multiple-camera systems are also possible with the proper accessories. Hard-wired security camera systems involve more labor because of the need to run cable. Wireless technology has made it possible to more quickly set up security cameras and related accessories on the interior and the exterior of homes or businesses. The homeowner or businessperson must first determine what areas need coverage. In a home, the coverage space may consist of a door, windows or driveway. Businesses may require coverage of a door, cash register, and storage room or product aisles.

Wired or Wireless
Although wireless security cameras have become affordable for the average person, they tend to cost more than wired security cameras. Some factors to consider when deciding between wired or wireless security cameras includes the size of the home or business and the interior and exterior surveillance spaces. In addition, the user must decide on the placement of the cameras and any accessories required for accomplishing the objective. Keep in mind that hard-wired and wireless system both require a power source. When installing a wireless camera, factor in the distance because these cameras have ranges from 100 to 1,000 feet.

Other Considerations
Generally, the standard resolution available on most cameras, or the clarity of the footage, is adequate for most people. However, users should decide on features such as resolution and night vision on a case-by-case basis. Exterior security cameras must have weather-resistant housing. Another decision involves whether the images provided by the camera will be monitored live or recorded for viewing later. Recording system options include videocassette recorders (VCRs), digital video recorders (DVR) and DVR cards. DVR cards enable recording and storage on a computer. Some users install security cameras with motion detectors. These devices record only when activated by movement.

Camera Types
"Nanny cameras" are security cameras inside a lightweight, compact housing that allows concealment in everyday furnishings and objects. Many homeowners choose this type. IP cameras plug directly into the computer and allow live viewing or the recording of footage over the Internet. One of the most popular security cameras for businesses is the Dome PTZ (pan/ tilt/zoom) camera. The 360-degree flexibility and capacity to zoom in on objects or faces make this camera very popular for keeping tabs on parking lots, building parameters, large warehouses and other spaces. Bullet security cameras, so named because of their bullet-shaped housing, are popular for surveillance of exterior surroundings.
