Raising and Lowering Security Cameras

[wizzaarrdd@xxxxxxxxxxx]

I was told that there was a device that will raise and lower a
security camera. I guess it would be some thing similar to a flag
pole. I have an issue where I need to have a PTZ camera mounted 20
feet up a pole. My contractor has aimed towards health and safety
rules where they will not climb a ladder above 10 feet high. If you
can find a 6' 6" technician then he may be able to reach as high as 17
feet. If any higher I need to pay for a lifting device such as a
scissor lift or a boom lift. I was told that there is a pole that you
can mount a camera on and raise and lower the camera. I have searched
for such a device and have had no results. Anyone ever heard of such a
thing?
