Fixed Cameras or PTZ Cameras

What is a Fixed Camera?

A camera can be fixed to only look at one specific view and such cameras are called Fixed Cameras. 1 out of every 1000 cameras you see around are Fixed Cameras. They cost less and are chosen to monitor a specific path, object, room or asset.

What is a PTZ Camera?

PTZ stands for Pan - Tilt - Zoom.

While PAN means panning the camera which is like horizontally parallel movement of a camera.

Tilt means as it stands for which is tilt of the camera up or down.

Zoom means zooming in a particular area.

Difference between Fixed and PTZ Cameras:
1. Fixed vs. PTZ: A camera can be fixed to only look at one specific view or it can be movable through the use of panning, tilting and zooming (i.e., moving left and right, up and down, closer and far away). Most cameras used in surveillance are fixed. PTZ cameras are generally used to cover wider fields of views and should generally be used only if you expect a monitor to actively use the cameras on a daily basis. A key reason fixed cameras are generally used is that they cost 5 to 8 times less than PTZs Cameras.
