ROV Cameras

Extending Your Camera We want your ROV to be able to see the sea! (And the pool)

Extending Your Camera Extending your camera cords: UnderwaterTopside Camera Female-male end of cable RCA and Power cable Female end and adapter Female-female end of cable Cable from camera box (Red RCA Video Plug) Control box Monitor Monitor attachment Camera filter

Extending Your Camera In 3 Steps: 1.Reattaching the Camera to the Power/RCA Cable 2.Constructing and attaching the Camera Filter to the Monitor 3.Attaching the red RCA Video Plug to the camera system

1. Camera to RCA/Power Cut all four plugs with wire cutter Male end Female end Adapter

1. Camera to RCA/Power Use wire stripper to strip all four wires (outer and inner layers) DON’T FORGET TO SLIDE IN THE HEAT SHRINK BEFORE YOU START SOLDERING!!

1. Camera to RCA/Power Connect and twist wires (yellow with yellow, red with red, and black with black) NOTE: Heat shrink for individual wires not shown here!

1. Camera to RCA/Power -Solder wires together (using solder and soldering iron) -(NOT SHOWN: add hot glue over solder and slide heat shrink over all wires)

1. Camera to RCA/Power Use heat gun on heat shrink until the hot glue melts and oozes out the sides of the heat shrink – that’s when you know it’s been waterproofed Be careful not to burn yourself!

2. Camera Filter -Electrical noise from the ROV motors can cause voltage spikes that will damage or destroy delicate camera electronic components -Voltage spikes will also cause video signal disruption every time a motor is running -A simple camera filter will remove any issues and provide “clean” power to your camera

2. Camera Filter Camera filter in relation to everything else

2. Camera Filter Camera filter parts One meter of black/red power cable Capacitor Ferrite core Diode

2. Camera Filter Electrical schematic for the camera filter

2. Camera Filter -Loop the power cable around the ferrite core ten times or as many times as you can (at least nine times) -Split the red and black wires apart Monitor side Control box side

2. Camera Filter Cut the red wire and strip it to show the copper wires inside (using the wire cutter/stripper) Make sure the GRAY stripe on the diode is facing the ferrite core!

2. Camera Filter Cut the leads (metal wires) on the diode to 1 cm on each side Leads now 1 cm on both sides

2. Camera Filter -Twist copper wires around the leads -Solder the wires and leads together NOTE: Waterproofing not necessary since this will be topside

2. Camera Filter -Wrap diode with electrical tape -On the other side of the ferrite core, split the red and black wires -Strip the red and black wires to add in the capacitor

2. Camera Filter Polarity is important! The negative (shorter) lead of the capacitor should be wrapped around the black wire and the positive (longer) lead should be wrapped around the red wire POSITIVE=LONG LEAD NEGATIVE=SHORT LEAD

2. Camera Filter -Solder the capacitor onto the wires -Wrap leads with electrical tape or use heat shrink NOTE: The two capacitor leads MUST NOT BE TOUCHING!

2. Camera Filter Now on the capacitor side, we will connect the camera filter to the monitor Monitor side Control box side

2. Camera Filter -Strip, twist, and solder the red wires together and the black wires together -Wrap with electrical tape Monitor side Control box side

3. Attaching Red RCA Plug -Locate the red RCA plug and arrange the red RCA plug that came with the camera -Arrange it so that the plug will attach to the black plug and the loose end can be soldered to the camera filter Monitor side Camera filter side Finished camera filter

3. Attaching Red RCA Plug -(Between the capacitor and the place where you connected the camera filter and the monitor cord) strip and solder the red RCA cable wires to the camera filter -Red to red and black to black

3. Attaching Red RCA Plug Result of soldering red plug RCA cable and monitor cable to camera filter Monitor side Control box side

3. Attaching Red RCA Plug Now plug in red RCA plug BEFORE AFTER

3. Attaching Red RCA Plug Result of attaching red RCA plug to the camera system

Waterproofing Camera Use the provided silicone caulk to seal the camera’s crevices

Waterproofing Camera Seal the front seam of the camera without blocking the lens

Waterproofing Camera Seal the seam around the sides of the camera

Waterproofing Camera -Seal the back of the camera (where the cable goes in) and the screws -You may need to remove the bottom stand to seal this

Waterproofing Camera Your finished, waterproofed camera is ready for testing!

REMEMBER! -After each step of wiring, it is advised to test the connections and make sure your circuit is working! -Don’t forget to waterproof everything (all individual wires and components) that will be underwater. -Never leave any wires exposed – SAFETY IS MOST IMPORTANT! -GOOD LUCK!
