PTZ Cameras are mainly used in environments where there is someone to operate them. They normally contain these aspects
- PTZ cameras are known as Pan / Tilt / Zoom Cameras.
- A PTZ camera can be adjusted at any time by the user to move and look over a 360’ area. Potentially you could follow a suspect as he moves through the area the camera covers. This would require an operator to do this manually unless PIR sensors are connected to the camera. Cameras can also zoom into specific areas providing a much more enhanced view.
- In simple terms PTZ cameras look like dome cameras but on a larger scale. (images are shown below)
- The PTZ camera can be wall mounted, pole mounted or ceiling mounted. In essence they can be mounted to anything.
- The PTZ cameras are generally varifocal allowing complete control of the viewing angle. But they can be fixed if they are in a smaller form factor and covering a smaller area.
- PTZ cameras are normally vandal resistant. They are normally placed in ahrd to reach locations to reduce risk.
- A bullet camera normally provides a colour image. There are also thermal bullet cameras available.
- Most PTZ cameras these days come with infra red light built in which provide night vision. These only come on when the camera detect low light levels such as night time. Many PTZ cameras may also not have infa red. Its location and exact environment will determine whats best to use.
- Enhanced housings are available for PTZ cameras which can provide increased strength from vandals. Water/Rain resistance. Or for use in specialist environments such as highly toxic environments.
- PTZ can come in many different colours. But normally they are white. They can also be spray painted if done correctly. (this may void the warranty in some situations)
- PTZ cameras are supported in IP, AHD, Analogue & HD.
- Bullet cameras can run on coaxial or Cat5 (networking) cables depending on the camera purchased.
- Bullet cameras will generally require an additional power source as a lot of power is required to move the camera inside the dome up and down and left and right.
