What Are The Benefits Of Nitrogen-Filled PTZ Cameras?

Is a nitrogen-filled camera more reliable over the long term than a standard PTZ or bullet camera?

A: Yes, definitely, and particularly with PTZs with motors, gears and belts. One of the advantages of pressurised nitrogen is that it excludes air from the housing and that means it excludes moisture, dust and airborne solvents and chemicals, too.

No air means no condensation. Nitrogen is inert thanks to its simple molecular structure – it only has 2 atoms – this simplicity means it doesn’t break down as part of chemical chain reactions. What this means is that there’s no rust and no corrosion possible in an atmosphere of nitrogen – it’s also environmentally friendly – Earth’s atmosphere is about 80 per cent nitrogen.

While nitrogen-filled cameras are robust, you need to ensure that seals are maintained – a stainless V-band with latching helps with pressure sealing. A nitrogen-filled camera should incorporate a pressure sensor that reports low nitrogen levels and mechanically, there needs to be a pressure relief valve and a purging valve incorporated into the camera housing.
