Considerations
Side/extra wall
coverage
Extra coverage can be gained in open entrances that have hard obstacles on the
sides of the entrances, such as mall entrances, as people approach the entrance
walls. Since most people's center of mass rarely comes within 0.5m (18in.) of a
wall beside them, extra coverage is gained at the walls. This only holds true at the
walls — not at coverage boundaries between two sensors. So, if you install two
sensors, the extra coverage gained at the walls is still only the 0.5m (18in.)
beside the walls.
Side wall coverage gains
These coverage gains are most likely in the following situations:
n Doorways with swinging or sliding doors
n Doorways with security panels
n Areas of low traffic (under 50 tracks per hour)
Side wall coverage gains are only possible in situations where the track crosses
the sensor’s field of vision for the amount of the minimum track distance
threshold, which by default is 90cm (3ft).
NO side wall coverage gains
NO coverage gains between two sensors
