Surveillance Video Cameras Security Systems

Introduction 

It seems, include all set up for all cases of life for all environments, for very different light, for covert and overt surveillance, to work with a minimum distance or at a respectable distance. For any project of guarding the complex can, in principle, to pick up the camera, responsive to the needs to the fullest extent. But manufacturers are even more foresighted, offering versatile camera let you change lenses. The difference between these cameras and more familiar with non-replaceable optical block - some as between SLR and soap holders "- the former are more versatile and functional, the latter - a simple and cheap. For whom do you design a video surveillance cameras with interchangeable lens system? Surprisingly, such cells need a lot. For example, they allow you to choose the optimal viewing angle or the optimum increase, if you are limited in choosing a place to install the camera. Also, they allow no change or even a significant move the camera quickly to restructure the system of observation when changing the configuration space, for example, in the warehouse complex. Finally, they allow the use of such a lens, which is the best way suitable for the existing lighting conditions. In the end, not necessarily buy the right set of optics, but you can choose the optimum lens. On two of these cells from ORIENT us today and talk, at the same time see how the picture changes when changing optics. 
Cameras 

We consider the two chambers, it is ORIENT BP-200 and ORIENT CP-315. Both of them have a classic rectangular design, both use a standard lens C / CS-mount, both are characterized by high reliability and durability, as collected in aluminum housings. 

The first of the cameras - ORIENT BP-200, is pictured on the right - contains monochrome matrix production LG, its diagonal is 1 / 3 ", resolution - 480 TV lines. The camera allows you to control aperture, which has a special connector. It produces good image quality, the lower threshold of illumination is 0.1 lux, a lens aperture of 1.2 or more "light". On the back side, but the video output and BNC connectors for operation of the diaphragm, automatic control switches are electronic shutter (AES) and automatic brightness control (BLC). 

Second camera - ORIENT CP-315 - is different in that provides a color image. It set a matrix size of 1 / 4 "output Sharp, provides 420 lines of horizontal resolution, in light of the need for this camera is somewhat higher, but no significant difference. The back side of the silver metal body contains the socket for the operation of the diaphragm IRIS, a video output BNC, automatic exposure control switches (AES), automatic brightness control (BLC) and, in contrast to the monochrome ORIENT BP-200, the switch automatically white balance (WB). 

Both cameras have a standard thread tripod mount, and on the body ORIENT BP-200 is a hole and the bottom and top (for mounting on the ceiling), and the model ORIENT CP-315 assembly is installed below ground, but it can be transferred to the upper side, holes for fasteners are available. 

In any of the cells photosensitive matrix is shallow, so when the lens is not installed, a protective cover mount is better not to neglect. In terms of resolution and sensitivity of the matrix of both cameras are good opportunities, but the quality of the final image will also depend on the correct choice of
