  • Page 17: Section 3. Mounting - Camera Base

    MOUNTING - CAMERA BASE Caution: The selected mounting location should not place the camera in a situation where its environmental specifications could be exceeded. See page 27. Ensure the selected location is protected from falling objects, accidental contact with moving objects, and unintentional interference from personnel.
  • Page 18 The mounting holes are configured for a single-gang electrical box or a round ceiling electrical box. The camera base can also be mounted to any flat surface. See the template on page 26. It would be advantageous if the power and video wires from the remote source could be routed into the electrical box at this time.

  • Page 22: Section 4. Camera/Led Adjustments

    CAMERA / LED ARRAY, ADJUSTMENTS For optimum picture quality the camera lens must be as close as possible to the dome’s inside face, without touching. However, the foam ring around the lens should be adjusted to seal against the dome, minimizing any side light interference, but without obstructing the field of view.
  • Page 23 Note: Gasket Back Cover - Some products have a paper backing on the gasket. Please remove it before installation. Mounting - It is recommended that the camera be mounted to a flat non-porous surface for best results. The mounting holes and the area around the mounting screws should be sealed with silicone to prevent water or moisture from entering into the unit.
  • Page 24 Note: If light reflects from side walls or other adjacent surface, some bright spots or halo may appear on the image. Move lens away from the reflection surfaces in order to avoid back reflection. FIGURE 4 – 1 Camera Lens Directional Alignment...
