Have box type body with the ability to use various types and sizes of lenses. Exchangeable lenses enable this camera, to monitor objects from virtually any distance. Although to be used indoors, they can be used for outdoor when combined with weatherproof housing. They are considered the most flexible and widely used by professionals for commercial installations.
Bullet camera.
Bullet cameras are, as the name suggest contained inside the bullet-shaped housing. some bullet cameras will even have infrared LED future built-ins. Infrared technology is only LED light in the infrared spectrum (not visible to the human eye). This light will illuminate viewing area, making monitoring possible in complete darkness. This is a great future, but it only works up to a certain distance (usually between 10 and 50 ft, depending on model) Vary simple to install and estheticly designed, bullet cameras are great choice for residential installations and do-it-yourself where monitoring objects are within about 25ft from the camera location (with standard 3.6mm lens).
Board camera.
Board Cameras are basically fixed lens mounted on the circuit board. This camera can be packaged in a small case (Mini Cameras) or dome (Mini Dome) or simply sold unpackaged, for mounting by the buyer. Lenses in this is one of the normal industry aperture or a "pinhole" lens of very small openings. pinhole camera lens is often called "spy" cameras and can be installed in a hidden secret for surveillance purposes. The most popular examples of covert board cameras are smoke detector and motion detector.
Because the camera lens on the board of pre-mounted, have a fixed iris and usually of short focal length (ie wide angle), their flexibility of usefulness is limited. However, the type of camera can provide low cost solutions in the right situation, especially in the home environment. We have long been portrayed most popular types of cameras, lets now discs, how and where they mite be used.
Professional types with C / CS mount lens attachment generally offer best performance and future importance, such as lens control output, Back Light Compensation and many more ...
Distance from monitoring object to the camera is not a problem, which is why the ability to select different lenses, based on the location is very important. Installation a bit tricky and professional installation is highly recommended. We recommend the type of security cameras for commercial installations.
