Good question. First lets address the issue of the Cat5e. This is a data wire. I am not 100% sure as to whether cat5e will in fact be able to distribute the video signal and power to the camera. You will have to check with any equipment manufacture that sells cameras. The ones I use work with an RG59 for video and 18/2 for power. Now, about the distribution to your TV's. THis is easily done. You just place an FM modulator in line on your cable feed before in splits to the televisions. The FM modulator allows you to set a certain channel such as channel 100 so you can access the camera video on any TV. For example you would need a single FM modulator to run only to the kitchen TV. You would need a multichannel FM modulator to run to every TV including the kitchen TV. It is a decision you would have to make based on price difference. Some FM modulators get pricey. A word to the wise.....Cheap FM modulators will go bad very often. It is worth the money to buy quality.
