Stage 3 –
Beam Alignment
- The GJD is supplied with two Fresnel lenses to provide a beam
pattern best suited to the cameras field of view. The 50 metre X 10 metre lens is
fitted to the unit when manufactured. If required this can be changed to the 50
metre X 5 metre lens which is supplied with the unit.
- Movement across the beams produces the best response and range, whilst
movement towards the detector will be less responsive. The unit detects the
changes in heat and movement in the beam pattern, therefore items such as trees,
shrubs, ponds, boiler flues and animals should be considered when positioning
the detector.
