Sighting requirements
Observe the following:
Ensure the mounting position is free from vibration or movement •
Prevent accidental knocking or forcing out of alignment •
Where snow or ice build-up is likely, the heater should be enabled •
To ensure the best possible video image the detector should be facing away from the sun •
Isolate as far as possible from local electrical interference sources •
Ensure su ffi cient detection to achieve adequate coverage for all likely hazards •
Minimise exposure to contamination of the detector face plate •
Ensure ease of maintenance access to detector (i.e. direct, ladder or sca ff old access) •
All these issues are of crucial importance to a successful installation, and they should be given great attention during
the detailed design, construction, and commissioning phases of the work.
