PTZ Calving Camera

PTZ (Pan, Tilt & Zoom) are very useful when you want to view large shed areas with a single Camera. You can control the viewing angle of the Camera. If set up to have a two way communication between the Camera and PC the viewing angle can be changed remotly from the PC.

Here is a small animation of me panning the Camera around the Cattle Shed. In reality the picture quality is better and is less jumpy. The resolution was reduced to save on bandwidth, but you should get the idea.

Panning camera viewing angle around shed

The most common, and popular, type of Camera with PTZ functionality is an IP Camera. All IP Cameras have two way communication between the Camera and the Host. What I mean by two way communication is that the IP Camera sends data (video stream) to the Host PC and the PC can also send data to the IP Camera (configuration settings or viweing angle changes).


  • Can view large areas with a single Camera
  • Less Cameras required
  • Can change the Camera viewing angle easily
  • Zoom in on a targe to get a better picture


  • Need to have a two way communication between Camera and Computer
  • More expensive than static Camera
