First of all see what a PTZ camera.
PTZ means in English Pan / Tilt / Zoom. It is the movement that the camera is capable of performing. It may therefore pivot on the horizontal axis (Tilt), vertical (Pan) and zoom! These basic movements allow the PTZ to climb on the course of the most powerful cameras and more suitable for monitoring large areas.
They also have the particularity to operate in total autonomy, as their movements and actions are configurable. It is also possible to determine the actions to perform in certain circumstances, for example when motion detection, start recording, and rotate the CCTV camera to monitor the individual.
Although they are autonomous, these CCTV cameras can be completely controlled manually via a joystick or a computer.
PTZ CCTV camera also has the advantage of hosting the two main transmission technologies, namely analog and digital. We speak in detail of these technologies in dedicated guides: digital cameras Guide and analog cameras Guide
While both technologies are available on PTZ cameras, the operation thereof is different. The major difference resulting from the choice of technology to the management of the camera movements.
The video signal is transmitted through the coaxial cable connected to the CCTV camera.
It is supplied with energy by a cable to share.
The movement orders are transmitted from the recorder to the PTZ by a twisted pair cable.
We must therefore take three different cables to operate an analog PTZ camera.
(Details in the analog cameras Guide )
Digital technology can transmit more types of information through the same cable. (Details in the digital cameras Guide )
The video signal and power CCTV camera pass through the UTP cable used (in the case of a camera POE)
The same cable can also be used to trnasmettre movement orders in case the checkpoint is not too far from the camera.
Note that the use of digital PTZ for easy installation.They also offer more functionality at the video analysis.
In order to have complete control of your camera and learn the full potential, there is some essential accessories to have.
It controls the movements of your PTZ intuitively and easily. The three-axis joystick allows easy management of the rotation, tilt and zoom the camera.
The keyboard allows commands directly on the recorder.
Most PTZ domes are standard equipped with a weatherproof case. This is essential if you want to install your cameras outside.
If the casing is valid to IP66 standard, it then guaranteed tightness rain, dust and protected against strong water jets.
Some said housing Anti-Vandals’ are strong enough to withstand degradation by voluntary by man.
Especially useful for indoor recordings, microphone fits the camera to record the sound along with the picture
