Before installing the SharpX camera units on the roof, you must perform some pre-installation steps to prepare the vehicle.
Before you begin
What you should know
- The SharpX mounting base is comprised of four parts, the threaded base block, two rubber gaskets, and the upper mounting block. The upper and lower mounting blocks are placed above and below the roof with the rubber gasket in between to prevent water leaks and reduce vibration.
- If you are using a magnetic mount, you do not need to perform these steps because you can remove the camera and reposition it as needed.
- Disconnect the negative (typically black) cable from the vehicle's battery. This is important for your safety and to prevent accidental deployment of the airbags.
Lower the vehicle's headliner to gain access to the underside of the mounting
location. The headliner does not have to be completely removed, but you must gain
access to the underside of the mounting location and to the area and locations where
you will route the camera cables. Depending on the vehicle, you may also need to
remove trim panels, sun visors, handles, and door gaskets to access the mounting
Using a panel removal tool can help in releasing the clips for the plastic body panels. You may also need a Philips screwdrivers, Torx bits and a flat blade screwdriver.
Identify any supports, braces, airbags, or wiring that may interfere with the
mounting plate installation and mark their locations on the top of the vehicle
As it is difficult to know what is directly under the mounting location, we suggest using the "tapping method" to identify obstructions. With one hand on the roof, and your other hand on the under-side of the roof, tap the roof and feel for a solid tap on the under-side. Using this method, you will be able to locate any obstructions and mark their location on the roof using a grease pencil.
- Place the upper mounting block on the vehicle’s roof where you intend to install the camera.
- Measure approximately 15 cm (6 in.) back from the corner of the upper mounting block and make a mark for the camera cable hole. Use the tapping method to verify that there are no roof supports that will interfere with the location.
Using a center punch, mark the upper mounting block (A) mounting holes (B).
IMPORTANT: Do not drill for the holes (C) that secure the camera to the mount.
Drill the mounting holes using a 3.175 cm (1/8") drill bit.
NOTE: Although the final hole size is 6.35 cm (1/4”), its recommended that you drill with a smaller drill bit – for example a 1/8” bit first. Drilling with a smaller bit allows you to make sure that the placement of the lower block is not impacted by the roof bracing and is easily sealed if the location is incorrect.
- Using the drill bit a guide, place the threaded base block in place and verify the location is not impacted by the roof bracing.
- If the mounting block location is good with no obstructions, switch to the 6.35 cm (1/4”) drill bit and re-drill all the holes for the mounting block.
- Deburr the holes to remove any metal shards or remnants.
