Board cameras are mini cameras that feature a lens mounted onto a circuit board. Their size – sometimes as small as one inch by one inch - makes them well suited for security camera system applications where discretion is important. They are often used for covert security camera system monitoring and many board cameras utilize pinhole lenses. The average hole size on a pinhole lens is 1/16” diameter. This is the only part of the camera that must be exposed in order for a picture to be obtained. There are two types of pinhole lenses – flat and conical. Conical lenses require a smaller hole and are often used in security camera system installations involving ceiling tiles and drywall, while flat lenses are better when the security camera system is to be used with thin material, such as clothing. All of our board cameras are plug and play, allowing them to connect directly to a TV or VCR. They operate using an AC adapter or batteries as a power supply. Transmitter and receiver combinations are available that allow for wireless board security camera system applications.
