Hello all!! I am new here and hope you can help me!!

I work in a church that is a few decades behind in technology and I am slowly removing and upgrading the various dinosaurs that are still being used as they die off. The current project is the video system. We have a system that runs closed circuit to multiple buildings by coax cable and the camera died last month. Simultaneously I am streaming our services via a webcam. What I would like to do is buy a setup that would replace both cameras and serve both functions. I know their is some conversion issues and do not care about having to buy conversion boxes or what not. What I really want to avoid is running new lines for the CCTV. I also don't need high end video just want to buy a camcorder in the 250-500 range. Anyone have a recommendation for camera, converter, software, etc?

Thanks in advance
