Recommendations for camera and monitor models
Posted by Sara Jablonski at 2015-05-20 15:54:01

Hi,

Some of the SeaPerch lessons require using an underwater camera with monitor. I would like to hear from others if they have purchased cameras that work well. If so, please share information about where I can purchase this camera.

Thank you.

We had some success with reversing cameras from Ebay, they are cheap and (mostly) water proof.

You can run the composite signal over another cable - it degrades the quality a bit but works OK.

Another approach (still being worked on) is to put a battery and camera underwater by using PVC storm water pipe and cutting a hole out of the end cap and gluing a circle of acryic over it. The other end is a screw fitting with a hole drilled in it and a 15mm pipe adapter screwed and glued in. The camera connects to the battery for power and runs the video signal over a balun (also obtainable on ebay for a few dollars) to the surface. The video cable passes through the end cap and is sealed with the wax used for the motors.

Having a sealed module underwater means you can use other cameras (although you want to make real sure it is sealed).

The primary issue so far is the sealing of the screw thread - it is quite fiddly to get right :(

I've attached some photos of the concept being used for something else.

Hello,

This is our first year in SeaPerch, and we had this question as well.  Thank you for posting it.  I was wondering, if we are participating in the stock division, does the addition of a camera count toward the $20 allotment over the kit of parts?

Thank you very much for your time and information!

Bryan
