How high will the cameras be hung?

It is important to know how high the camera will hang.
If the camera position is high above 3 meters then we recommend installing an Eyeball. 

This is because the dome camera cover will need to be cleaned from time to time.
This is not necessary with an Eyeball.

We recommend the Dome in low places because they are very vandal resistant and you cannot easily see where the Lens is looking.
