Page 3: Introduction
The mounting structure should be sold enough to resist significant movement in windy conditions. Movement of the VID-W20L030 caused by vibrations or other movements will result in changing fields of view covered by the VID- W20L030 and could cause erratic signals. These unwanted signals may lead to an increase in the alarm threshold level which reduces the detection probability or in certain cases can lead to unwanted alarms. -
Page 4: Vertical Alignment Of Vid-W20L030 For A Required Detection Up To Nominal Range
7.1 Vertical alignment of VID-W20L030 for a required detection up to nominal range The VID-W20L030 should be aligned vertically so that at a minimum the lower half of a person standing upright at the maximum required range will be within the field of view (see Fig. 1 below). -
Page 5: Adaptive Threshold Discrimination (Atd)
Switch 3 (ATD) Factory Setting Operation of the VID-W20L030 in this mode is possible but not recommended in outdoor applications as the nuisance alarm rate could increase significantly as a result of turbulences. When the unit is walk tested the threshold level will increase as a result of the signal generated by the target, it will subsequently decrease exponentially in time after the event. -

15 Internal Temperature Compensation The VID-W20L030 is detecting the radiation differences of a target against its background. In the course of a day and a year the contrast of a person will vary considerably and affect the signal strength. To compensate for this contrast variation, the VID-W20L030 has an internal temperature compensation with maximum sensitivity setting of approximately 30°C (where the contrast of a human target is weakest) and gradual reduction at higher and lower... -

It is therefore strongly recommended to combine the VID-W20L030 with alarm verification such as CCTV or a second system using other physical means of detection (e.g. VMD). • Any liability for direct or indirect damage resulting from the use of the VID-W20L030 as a detection device is explicitly disclaimed. •... -
