The difference in dead zones of the two technologies is an important factor to consider when the
PIR/camera combination is used. The PIR may have a very steep downwards angle, whereas a
camera may have a much larger dead zone, as illustrated below. This is a very important
consideration as a moving target in the camera's dead zone may activate the PIR. The target will
not be visible to the camera mounted with the PIR, however the target will be visible to the
camera covering the first camera's dead zone. If the PIR/camera dead zones require matching,
carefully check the comparative dead zones to ensure that this can be achieved.
Also consider mounting the PIR and camera on separate poles.

The installation and use of any detection technology should consider:
• The angle of elevation and the horizontal alignment with the camera is critical in providing a
high degree of performance.
• It is recommended to keep foliage trimmed and grass cut for a clear PIR and camera FOV.
• Termination barriers are important so that targets past the protected area are not detected.
• Minimise reflective material in the FOV to ensure reflections from sunlight do not affect the
PIR.
• Minimise facing PIRs in the direction of sunrise or sunset.
• PIRs also require a maintenance program to clean the lenses and to regularly check
performance and alignment.
PIR Alignment
For good PIR performance ensure PIR and camera alignment match. The following figure shows
the optimal PIR placement angle, where the top of the curtain is approximately 1m (3ft) high at
the maximum detection range.
Figure 12: Optimal PIR Angle
When using a long range PIR next to a fenceline, it is important that the PIR curtain is aligned
approx 0.5m (2 ft) inside the fenceline, as shown in the next figure.
