For installations with cameras that are hardmounted or attached to the patrol vehicle lightbar, you must drill a cable hole in the roof of the vehicle for each camera.

Before you begin

What you should know

This procedure includes the use of cable glands. Alternatively, you can use butyl tape to seal the cable penetrations. If you use butyl tape, a 0.6 cm (¼ in.) hole can accommodate one camera cable, and a 1.3 cm (½ in.) hole can accommodate two camera cables. If you use this method, install a rubber grommet to protect the cable and account for the grommet when calculating the hole size.

To complete these steps, you need the following:

Electric or battery powered drill and drill bits
Required when running cables through the vehicle roof or body panels.
Hole saw or stepping drill bit
For cable penetrations, you can use a stepping drill bit or you can use a fine-toothed hole saw designed for vehicle body panels which is depth-regulated and includes a pilot drill bit.
Grease pencil
Used to mark support locations on the roof of the vehicle.
Center punch
Used to mark drilling locations.
Cable glands
Required when sealing wire holes drilled in the vehicle’s roof.
NOTE: Cable glands are required for all cable penetrations. Ensure that you have the appropriate glands in installing a cellular antenna or satellite navigation antenna.
Butyl tape and isopropyl alcohol
Required for sealing any cable penetrations that do not use a cable gland.

Procedure

  1. Choose an appropriate cable gland for the 0.6 cm (¼ in.) camera cable.
    WARNING: Do not run more than one cable through a cable gland.
  2. Place the cable gland on the section of the vehicle roof where you intend to pass the cable. Use a pencil to trace the outline of the cable gland.
    IMPORTANT: The hole should be slightly smaller than the outline of the cable gland so that the cable gland collar can grip the vehicle’s roof.
  3. Check that both sides of the roof are clear of anything that could be damaged, and then drill the hole.
  4. Deburr the holes to remove any metal shards or remnants.
  5. Install the cable gland in the camera cable hole.
  6. Pass the camera cable through the cable gland.
    Leave approximately 20 cm (8 in.) of cable to allow the connection to the camera. A simple distance check is to lay the cable across the hardmount plate. To ensure that you have a proper loop for connecting to the camera, the tip of the connector should reach to the far side of the plate.
