Hello, I'm new to CCTV. Last summer, I installed a basic CCTV system on my house. It's an 8 Ch Lorex system. Edge2 DVR, with various dome cameras and one PTZ camera around my house. I just installed a new garage door opener (Sommer Direct Drive). The transmitters operate on 310 mhz (rolling code). I'm having issues with the transmitters. They work terribly from outside my garage (from the driveway/street). I literally have to drive right up to the garage door to get them to work at all. I'm not done tracking down where the source of the RF interference is coming from (i.e. From one specific camera, from the DVR, all of the above? etc). But, it does appear that it has something to do with my CCTV system. I unplugged my surge protectors that all my CCTV stuff is plugged into the other day, and I was able to open my garage door from the street as I was driving toward my house. So, I'm wondering if anyone has run into this before. What kind of options would work for me? Can I try installing those magnetic ferrite cores (beads) on all of my equipment? (on the camera power cables, DVR cable, etc). Can they be installed on the video cables, as well? http://www.amazon.com/gp/product/B009U14CVI/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=AAQ3GHQN09UUL Also, should I try replacing my surge protectors with power conditioners that have RFI/EMI decibal suppressors? http://www.amazon.com/gp/product/B003BQ91Y6/ref=ox_sc_act_title_6?ie=UTF8&psc=1&smid=ATVPDKIKX0DER http://www.amazon.com/gp/product/B0083CZK9I/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A28V0P70G1J0LX Thanks!

Okay.. I tried disconnecting my garage opener's wall button from the opener. I read on a tech forum that the RFI most commonly gets in through that paticular wire. Acting as an antenna for interference. Wire goes up the wall, accross the ceiling, and into the garage opener. So far, so good. Got it to work from the street again after disconnecting it. I think those are my 2 main culprits. The CCTV system is throwing off some interference, and that wire is picking it up and feeding it to my opener. I also read on the tech forum that those ferrite cores placed on the wall button wire should indeed eliminate/reduce that particular problem, so that's what I'm going to try next. Well, its payday, so off to Amazon! LOL. Thanks again for the input

Thanks for the responses, guys. Yeah, I'm not sure why, either. My CCTV system never interfered with my older Craftsman opener (but, that was probably 315 or 390 mhz). I'm going to try unplugging my surge protector with the cameras on it again tomorrow, to see if the range increases again (to make sure it wasn't just a fluke). With the exception of my PTZ camera, most of my cameras have the cheaper siamese (black) BNC cable that you can get on Amazon. They're probably unshielded (or, low grade shielding) Yeah, you wouldn't think that it would affect something in the 310 mhz range, but after I did the online research on "Garage Door openers and RF interference", trusty me, you would be amazed at how many things can cause problems for the transmitters. Basically, anything that requires an electrical outlet can cause a problem LOL Routers, street lamps, refrigerators, furnaces, plasma TV's, A/V equipment, fluorescent lights, LED lights, baby monitors, alarm clock radios, etc, etc. Yes, I've tried fiddling with the opener antenna.. straight down, up, sideways, etc. I even bought some doorbell wire and extended the antenna outside of the garage. None of them seemed to help. I don't want to crawl around in my attic rewiring my CCTV (what a nightmare), so I'll just have to try some new things. I'll try some new surge protectors with RFI/EMI suppressors, some ferrite cores on my cables, and maybe plugging my surge protectors into a different outlet, etc, etc.
