Network PTZ Camera

A PTZ camera or pan tilt zoom camera is capable of remote directional and zoom control. As the name suggests, the camera has the ability for pan, tilt and zoom. There are other kinds of camera like ePTZ or virtual pan tit zoom camera which is equipped with high resolution allows to digitally zoom and pans into portion of the image without moving camera physically. VPTZ is used with ultralow band width surveillance technology to stream user defined areas in high quality without increasing overall bandwidth usage.

Camera surveillance through these cameras is done by connecting them to digital video recorder which records the full field of view in high resolution. Now there is a built in firmware programme that monitors the change of pixels generated by the video clip in the camera. When changes in pixels occur due to the movement of subject within the camera’s field of view, the camera starts following the movement. It also analyze the size of the size of the subject and also its distance from the camera. With the help of these calculations camera itself adjusts the focal length in and out in an attempt to stabilize the size of pixel fluctuation as a percentage of total viewing area.

When the movement exists the camera’s field of view, it automatically returns to its actual position till it detects the next movement.

Pan tilt zoom camera is an integral part of these days video camera surveillance. With the help of feature auto tracking as explained above it can direct its attention to suspicious movements also follows and observes them.

Benefit of having PTZ camera:

It provides large field view can cover 360 degrees area.

It has built in motion tracking system to detect suspicious events.

It is water and weatherproof

It has powerful zooming in capability for analyzing subject closely.

Multiple alarms for glass breaking, motion sensing, door contacts etc.

It is tampering resistant as made up of high quality metal and glass

It is simple to install.
