Advice for Correct Auto Tracking Use
General warnings
The tracking function should mainly be used in indoor environments. Outdoor use is highly
problematic: the variety of objects (leafs, flags, litter, etc.) moved by the wind makes use unreliable.
Provide the best lighting possible in the detection zone: in poor lighting conditions, the inevitable
presence of noise on the image makes grayscale variations extremely critical. In poor lighting
conditions, the camera may easily loose the tracked object.
If IR illuminators are use, remember that:
The camera must be programmed to operate in B/W only (SETTINGS 1/CAMERA/OTHERS menu)
because the Slow Shutter will make tracking unreliable in color mode
The lighting entirely covers the frame where motion is tracked, possibly by restricting the range of
action of the camera in tracking mode (using the TRACKING BOUNDARY option).
Avoid background objects in the frame which could trick the motion detector, such as for example
Venetian blinds, gates, doors with grid and objects with very marked, contrasting contours. A
chequerboard background is certainly the worst condition for satisfactory operation.
Do not use the privacy zone function in frames where auto tracking is used: the privacy zone can trick
the auto tracking function.
Do not use the auto tracking function if the object to be tracked and/or monitored moves too fast.
Recommended control parameters
SIZE SENS: select SMALL particularly in poor lighting conditions to improve performance.
GRAY SENS: most false alarms are caused by the tracking of unexpected objects. For this reason, it is
preferable to select low sensitivity.
ZOOM SETTING: it is advisable to use the lowest possible zoom values. Excessive detail makes tracking
difficult (the movement must be fastener and consequently or the risk of loosing the object is much higher).
WAIT TIME: particularly, in the case of poor lighting conditions or frames with interference, it is preferable to
set the lowest possible time to prevent the camera from constantly tracking unexpected objects (e.g. “video
noise” in the frame).
TRACKING SPEED: the AUTO setting should always be preferred, unless the object to be tracked does not
always move at low, constant speed.
TRACKING BOUNDARY: it is strong advised to delimit the tracking zone, avoiding including unnecessary
parts in the frame.
