Thanks for the warning, but I am aware of recording other kids around. I will record my own son and any other that the parent is present and would like to see his/her stroke or technique. We will review it right there in a regular old TV. The idea is to show the swimmer what are they doing correctly and what do they need to correct. I am sure if my son improves, ALL OF THEM are going to ask me for some video review. Again, thank you very much for be aware of potential legal issues with my experiment, I appreciate your input in that regard. I know that there are some cameras to use under water but I am not planning to get in the pool and hold my breath and record it, so an "extension camera" would do the job. Remember that my recording camera (no the CCTV) is capable of recording from an input port, so the CCTV camera would work as an extension that can be submerged to analyze his technique. I am not going to be able to zoom in or out so I already set it to a clear view at about 6 feet from the object. Too close is not that good, I need to see his entire body for the analyses. Some swimming schools do that but the equipments are very expensive and our small team does not have that money available. I will do that few times to make some corrections with the help of the coaches and again some time later to see if he has made the corrections. Thank you, Carlitos

Soundy and Survtech: Thank you very much for your quick response. I think it will work well for what I am planning. The camera I am going to use to video my son swimming and the signal recorded into my video recording camera from Apitek that can record from external source. I just need it for short time to see how his technique under the water and his turns are. The power or batteries are going to be out of the water with me. A power/video cable will provide the power to the camera and the video signal back to my recording camera. I will be able to change the batteries as needed. I will use an aluminum bar to attach the CCTV camera an keeping it submerged. I will add a on/off switch to power it as needed. It is a project that I hope will stay under $100-$150 instead of $1,500 for some "professional" ones that the small club cannot pay for. Regarding the battery arrangement, you gave me new ideas that I will review and probably test based on the initial try results. I guess all the little boys and girls will be happy with the new toy and the posibility of improving their times. Again, thank you for your response and support. Carlitos.

I am trying to use a CCTV camera under water with proper protection. The camera spec is for 12V and it has IR for night vision or low light environments. 12 Volts is not a easy battery to find and they are expensive. I removed the IR part of the camera, used an 8 Volts power supply, and seem to be working well but I have tested it for just few minutes. My idea is to use a pair of 9 Volts batteries in parallel to get enough amps for the camera so it does not run out of power too quick (I do not know how long it will last so far) My question is, Can I use a 9 Volts battery safely or will it damage the camera? I know that more voltage could fry the camera but I am not sure if low voltage does the same or so. Since I already tried the camera with 8 Volts for few time (less than a minute) I suspect that the requirement of 12 Volts is divided between the IR needs and the camera needs. Having disconnected the Ir section, will it be safe using just 9 Volts? I hope I am not making an stupid question and I appreciate any help on that regard. Thank you, Carlitos.
