Purchasing covert surveillance cameras is a lot like buying a computer. You're faced with a dizzying amount of abbreviations, acronyms, bandwidths, frequencies, and the like. Resolution, lux, megahertz, amateur bands, what's it all about?

Choices Abound among Covert Surveillance Cameras

First of all, resolution is important because it refers to a camera's ability to reproduce clear images. Lux meanwhile speaks to the amount of light spy cameras need to be able to record a scene. The optimal specifications for a great camera are high resolution, and low lux.

Covert surveillance cameras are either attached to a TV or a VCR, or they are wireless. For wireless surveillance systems, the distance of a camera to its receiver depends on the range of its signal. A 2.4 GHz transmitter is often recommended because of its superior video quality.

A camera with a 2.4 GHz signal can have a very large range, varying from 200 feet to 700 feet, depending on conditions. Covert surveillance cameras also exist with a 434 or 900 MHz range. A 434 MHz wireless frequency can carry from 300 to 400 feet, on up to 1,000 feet, while a 900 MHz amateur band varies from around 200 to 700 feet.
