A.2 Mount/Mounting Surfaces
– Mount the camera in the most stable position. Avoid locations affected by vibrations,
such as those caused by a roof-top air conditioner. These vibrations may cause
complications when the camera zooms-in on a target.
– Use the pendant arm mount, if possible. This mount option provides the most stability for
the camera.
– Use guy wires to protect against strong winds if using the parapet mount.
A.3 Field of View
– Select a location and viewing angle that allows the flow of people to move across the
camera’s field of view.
– Avoid motion that moves directly towards the camera.
– Avoid locations that attract large numbers of people, such as retail stores or
intersections.
A.4 Unwanted Motion
– Use the Virtual Masking feature (see chapter 7 in the VG4 200,300,500i Series User
Manual) to mask unwanted motion from trees or cars.
– Bosch recommends that you draw the virtual mask 10% larger than the object to be
masked.
– Avoid neon lights, flashing lights, night time lights, and reflected light (from a window or
mirror, for example). The flickering of these lights can affect the AutoTrack operation.
Use a Virtual Mask to hide these type of lights if they cannot be avoided.
– Check the virtual mask periodically to ensure that it still covers the entire object to be
masked. Adjust the mask if necessary.
