Installing the Camera Unit
The Camera Unit is normally mounted inside the trawl opening, or above the cod end.
Prerequisites
Image
•  You will need an ample supply of mounting materials (wires and ropes, hooks and shackles).
•  If you have a long camera cable, we recommend that you use a separate winch and cable drum to collect up this cable while the trawl is not in the water.
•  Floats.
Context
You may prefer to mount the Camera Unit at the top of the cod end to monitor the catch. You may, however, mount the camera wherever you wish provided that the length of the fourth-wire cable is sufficient. No matter how the Camera Unit is mounted on the gear, the most important task will always be to keep it from falling off during use.
Note
There are many different ways to do this installation, and many vessels have established their own procedures and “best practices” for these tasks. This procedure explains one method suggested by Simrad.
Simrad will not take any responsibility for any loss of or damage to equipment, even if our general installation and/or mounting procedures have been followed.

Procedure
1 Mount floats onto the Camera Unit to ensure that it is neutrally buoyant.
2 Place the Camera Unit on its chosen location on the fishing net.
3 Mount the unit to the meshes using a minimum of four wires or ropes from the metal frame to the net.
4 Adjust the angle of the camera and the LED lamp to fit the installation and the desired viewing angle.
5 Connect the two Y-split cable connectors to the sockets on the camera and the lamp, and make sure they are properly fastened.
6 Connect the single end of the Y-split cable to the connector at the end of the fourth-wire cable.
7 Place the fourth-wire cable around the eight-inch strain relief to take the up tension.
8 Tie the non-stretchable rope to the eight-inch strain relief.
9 Secure the eight-inch strain relief to the Camera Unit frame using wire and hooks.
Important
Allow for an ample length of fourth-wire cable between the strain relief and the Camera Unit.
