Explosion proof PTZ camera with 33X optical zoom.
A turning head in a certified body, for the rack, the tank farm or the process line where the camera cannot be reached and the view has to change.
Why zoom matters more here
A PTZ in a process area cannot be walked up to. The only way to read a gauge, a flange or a person on a rack forty metres away is optical zoom, and 33X inside an explosion-proof body covers a distance a fixed camera cannot.
The alternative is a fixed camera close to the object, which means a second certified body, a second gland and a second cable run in an area where every one of those is expensive.
The mechanical trade
Zoom costs weight. A bigger body loads the bracket more, and a turning head needs clearance to travel plus a service position that can be reached without scaffolding or a shutdown.
Settle the mount and the service position before the model. A PTZ that can only be serviced from a crane is a maintenance problem for the life of the plant.
Presets and who drives it
Set presets for the points that matter and let a tour cover the rest. The operator needs to know what the tour skips, because a camera that is looking somewhere else when an alarm fires is the usual complaint.
Ask who signs the acceptance and what document they need. On a plant it is the operator or the EPC, and each asks for a different file from the certificate pack.
