Looking for some help with a problem I'm having. My church runs Bingo once a week and has a very old system in place to display the drawn balls on monitors. The camera is a Panasonic CCTV Camera Model WV-1410. It has a BNC connection which runs a coax cable through the walls to four RCA monitors (Model TC 1115). I'm not sure what type of connection is on the RCA monitors... it's not BNC or regular coax... it's some sort of old school coax/banana plug hybrid from the eighties. The monitors are starting to fail and they need to be replaced. How can I go about this without breaking the bank? That is, I'd like to replace the monitors while keeping the same video camera and coax cables running through the walls. I thought that I could just use old flat screen TVs with a coax input... but it's not picking up a signal. I'm guessing the camera is sending some SECAM signal??? My next attempt was to use a RioRand CCTV BNC to VGA converter ($19 on Amazon) and connect it to a spare flat screen computer monitor. If that works, I was going to buy 3 more converters and use with 3 other spare VGA flat screen monitors laying around. However, I noticed the older monitors had an internal loop back where the coax went in and then came back out to feed the other monitors. Can I get around that with simple coax splitters? If that didn't work I was considering buying 4 new 19" Security Monitors off Amazon for $150 each. They have looping BNC inputs so I'm expecting that to work without too much hassle. Any advice on this or recommendations would be much appreciated? Any issues with my plan? Will the converter work? Should I just scrap the video camera as well and buy something else?
