I have a DCS 832 with a pc5010 control board and two lcd5500 keypads. All works as for as i know and is currently monitored by a local company. I also pay for warranty and they have replaced both keypads and some door sensors throughout the years since it was installed in 99. Issue now is I put it on a Ooma Voip which has worked or seemed to work for the past 10 years or so. In May started getting communication failure trouble lights. Had the company come out and look at it and the system is calling out but looks to be the VoIP that is causing the issue. I think something in Ooma system has changed. Cell service is terrible on this block and we have our cell phones hook to WiFi calling. They suggested putting in a cellular caller but I'm afraid it wont work as even outdoors its spotty. They said they could put in a internet connection but monitoring would run 40 a month. I''m thinking of canceling with them and putting a Eyez-On EVL-4 but want it professionally monitored besides being able to watch it myself. If the DCS works, is it worth it to just add on the new board and whats a recommended monitoring company for a self install or should i update to a newer updated system. I want to stay wired as much as i can. I don't have any issue with upgrading the system myself and actually would feel better knowing how, why and what makes it tick. I think the 40 a month is a bit steep for monitoring a internet connection, i might as well get a new landline for that, which just isnt going to happen.
