I just bought a go pro I don't think that can be hooked up as such. What is it that you have addy that your talking about I know your pond Is a good distance from the house is it blue tooth ?
I have two different security systems, all they do is watch the critters. One does watch the drive way.
I have one that is a older one, analog not HD it runs the underwater cam I have. A lightening storm wiped out the power supply just found the other power supply I had. Need to get it set up again. It is wired via a 100 foot cable to the house dvr. The power supply is run off the power down by the pond.
I just bought another "waterproof" cam, that will work with my other system so they say. I have not had the time to test it out yet. Need to make it a priority................
I have used the go pro to film the fish, but the security cam gives me a constant feed of the fish swimming around in the house on a small TV.
