In television production, PTZ controls are used with professional video cameras in television studios, sporting events, and other spaces. They are commonly referred to as robos, an abbreviation of robotic camera.
How high should a PTZ camera be?
The most appropriate height at which you should install your surveillance cameras is 7-8 feet. It is just above the easy reach of a vandal or potential robber and close enough to the ground to capture faces and valuable information.
How often should you replace security cameras?
Generally speaking, cameras will last anywhere from 5 years on up, keeping in mind the technology is only 20 years old. According to Security-Net, a new, current IP camera should last 2 NVR cycles. An NVR cycle is typically between 3-5 years.
