How to select the type of camera
Should you get a fixed position camera or a Pan, Tilt, Zoom (PTZ) camera? Go to each of the locations where you would like to install a camera and take a look at the area you would like to view.
Now let’s see what the camera will see. This is where your digital camera can be helpful. Hopefully you have one, but if not, this is a good excuse to get one. Decide on where you would like to place the camera, for example on a building or on a light pole, etc. Try and approximate the location of the video camera and then use your digital camera to view the area you want to view.
If you have to move the camera right and left to see everything, then you probably need a Pan, Tilt, Zoom (PTZ). If you have to move the camera only a short distance then maybe you can use a high resolution camera with a wide angle lens. If you can see everything with the camera in one position then a fixed camera will work.
