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.
