Home | Home & Family | Home Security Millions of people are using nanny cams to check on their babysitters, surveillance cameras to keep an eye on their homes and businesses and hidden cameras to catch theft, abuse and infidelity. No other method can give you the proof or evidence that a surveillance camera can. Board Cameras are basically a fixed lens mounted on a circuit board. These cameras are often used in mini cameras, dome cameras and for making hidden cameras but are also sold unpackaged, for mounting by the buyer. Lenses in these cameras are either of a full opened lens or pinhole in which the opening of the lens is very small. Pinhole lens cameras are often called "spy" cameras and are most often used in making hidden cameras. All of our hidden cameras are examples of hidden board cameras. Lenses in board cameras are pre-mounted and have a fixed iris. In most cases they have a short focal length (the distance between the surface of the lens and it's focal point) which results in a wide angle of view. Our board cameras have a lens between 3.6 and 6mm. Because board cameras have some many fixed features they are limited to what they can be used for. However, they offer a low cost solution to security needs especially hidden camera situations. A small board camera is built into an everyday item. The camera can be wired which means it is connected to the DVR or VCR using a cable. The camera can also be wireless, in this case the camera transmits a signal to a receiver that is connected to the DVR or VCR. Article Source: http://www.articlewheel.com
