Video surveillance systems: Design features of cameras
Are present at a line of each producer both cheap and standard on matrix parameters, and matrixes of the increased permission and/or hypersensibility. The directory of video surveillance systems and projects is available on TAdviser.
On design features of the camera it is possible to separate into the following types:
- Modular video cameras are the packageless devices which are usually intended for installation in the different body (casings, hemispheres, etc.).
- Minivideo cameras are video cameras in the square or cylindrical body which is usually used as a finished product to installation in premises.

- The gyrostabilized video cameras are the video cameras used on moving objects for the purpose of obtaining the stabilized image.
- As a signal output of the video camera subdivide on analog and digital (working on network) IP cameras.
- On a method of data transmission of the video camera are divided into wire and wireless. The last incorporate the sending device and the antenna. Signal transmission is performed at frequencies of 2÷2.5 GHz. To wireless Wi-Fi-video cameras also belong.
