Yup call yer alarm company. Also Im not too concerned about a wifi module or cellular module for your lynx. Since all your
devices are wireless you can always upgrade to a Lyric panel it has w/l , cellular and z-wave built in and you will not need to change yer w/l
devices. All these ip/cellular modules run on the secure channel. I,ve been playing around with the lyric and I'm quite impressed, nice screen and really easy to set up. You could always try an Uplink 4550 module (again secure but must be set up through your alarm co as with all secure monitoring). Stay away from trying to monitor on a cheap VOIP line they are not managed and will almost always fail. Total connect on the honeywell system works great it will also allow you to arm/disarm do home automation and cctv(works best with honeywell cameras) but will also work great with a Skybell for front doorbell replacement( skybell has no monthly fee and if you have a regular door bell the existing vac transformer will power it unlike ring, no
batteries to charge/replace if you dont get a ring or run a 16vac transformer and use a 10ohm 10w resistor or you WILL BLOW IT UP) all on your smart phone but for a small monthly fee(that is for the total connect portion, skybell can be used @ no charge without total connect if you choose). With more and more people dropping POTS phones I'm doing a ton of alternate monitoring, the cheap option is internet then cellular I charge an extra few dollars for alternate monitoring but your company may charge more or less. Sorry for my ramblings just telling like it is,
People want to cheap out, I get it, but I know what works and what doesn't, nothing but sadness when I get the "FAIL TO COMMUNICATE" service call. I've been in this game for 24yrs.
