What is a Board Camera?
- A board camera is the most basic component of any camera you see on this website or others. Board cameras are the "guts" of any camera system whether it be a dome camera, a CCTV Box camera, micro camera, hidden camera, spy camera, plus many more. These cameras are perfect for the person wanting a custom security camera
- Board cameras have a variety of uses, depending on your wants and needs. In most cases, though, they are mounted in order to work as spy or hidden cameras. As long as you know exactly what to do with a board camera, you'll be able to choose one (or a few) that has the features that will work best for you
- The most basic thing you should consider regarding a board camera or any camera for that matter is the lens. The lens is pre-mounted on a board camera and the iris is usually fixed. That means you cannot zoom in or out without an additional device or accessory. Lenses can also be pinhole type or full
- Pinholes, like their name suggests, are small lenses and are perfect for use as spy cameras. You can mount these on a table clock, a lamp, a baseball cap or even a teddy bear. Full lenses are bigger and will work well on dome or mini cameras to complete your surveillance system
- If you plan to use a pinhole cameras board camera for surveillance, you have an option as to whether you prefer to view activities in black and white or color. There are also lenses that afford you low-light viewing, usually indicated as a low Lux count. A good Lux count would be at least 0.05, although there are others that can go as low as 0.0003. The low number means that the board camera lens will still work in near total darkness. Resolution is also a key feature to look into when considering board camera usage. Videos of activities are much easier to view if the images are crisp and sharp

- How is the Frame Rate related to Picture Quality?
Quality can refer to both how detailed the image is and how fast the frame rate is. Frame rate is simply a measure of how many individual pictures make up the video. "Full motion", what you see on television and on VHS tapes, is 30 frames per second, or fps. Most often, security systems record at slower rates, which result in more jerky-looking images but saves tape or hard drive space, allowing longer periods of time to be recorded.
- What is a camera's format?
Camera formats are measured in inches: most surveillance cameras fall between 1/4" and 1". This refers to the usable image size created inside the camera. For most security systems, a small size is fine - 1/4" or 1/3" surveillance cameras dominate CCTV sales. Larger formats do not necessarily result in better images, but can be advantageous in dimly lit situations since they are able to gather more light.
- Why is Resolution important to consider?
Resolution refers to how detailed a picture the camera can see. The measurement to look for is horizontal TV lines (TVL). A normal CCTV picture is around 350 to 400 TVL, with high resolution getting up to 480 or 500. You need to make sure your entire system is capable of supporting that resolution. If your VCR records 350 lines and your monitor displays 400, the money you spent to upgrade to a camera with 500 lines is completely wasted.
