I have installed ( other than drilling the hole in the hull) an anchor cam.

Running wires from the flybridge to the upper helm would have been a challenge.

I was looking for video transmitters. The reviews were mixed , but I did find a few for about £200 that seemed waterproof.

Then I found this for £20!!!!!!

Transmitter and receiver in waterproof boxes. The boxes themselves are worth the £20,

I did not really have high hopes but it transmits as good as a wire with a high quality stable image.

The transmitter unit is in the anchor locker and the receiver on the flybridge helm - so I guess 25 feet - 30 feet or so.

If you are looking for transmitters as opposed to running wires this is a great solution.

They are 12v so I used a 24v - 12v dropper for £5 ish off eBay which fits in the box.

Hope it is useful

No idea why they are so cheap. End of line?

Quite the opposite. First to market. The 5.8Ghz band was only licensed by OFCOM late August 2017. It is primarily for home networks so is power limited.


Edit
Just looked up the power limitations. Severely power limited, 200mW per channel as opposed to a max of 16W. I think the premise is to stop overlapping interference in densely populated urban areas. I imagine 5.8Ghz will have serious attenuation but as you are only hopping a short distance....perfect. :encouragement:

Thanks J. I've just ordered one.

I wasn't going to bother with an anchor cam because of the wire run hassle but this will be worth a try.

So I can completely piggy back your idea , what camera have you chosen ?
 
Thanks for sharing this solution. Presumably you've wired the camera and transmitter to the local power supply for the windlass. Do you have a battery local to your windlass, or cables running to the bow from your main battery pack? Only asking because I'm wondering about voltage drop and noise spikes when the windlass motor is grunting, and whether this affects the picture?
 
This was a big problem. The voltage drop was huge. So in my case i could not use that supply.

I have had ( still is!) the boat in bits. There is a 24v supply in the forward cabin and if you remove a few fittings you can see the trunking that runs the windlass control wires from the helm. I used that access to run 24v to the locker and supply the chain counter and the video transmitter.

Each boat is different but there will be trunking forward to control the windlass so the principal will be the same.

Try the windlass supply - it worked for Hurricane but not for me! Each boat will be different .
