Rant: I figured cellular backup was a scam until a job in Council Bluffs proved me wrong
I have been putting in panels for a long time and I always pushed the plain phone line or internet path because the cellular module felt like an upsell I could not stand behind. Last month a customer out in Council Bluffs had their cable line chewed through by a squirrel about two days after I finished the install, and the panel went to cellular without a hitch and still called in the alarm when a door sensor tripped. Their provider wanted $180 to run a new line and I was out there with a $12 splice kit fixing the damage anyway. What got me was how fast the switch took, maybe 30 seconds, and the customer got the call on their phone before I even pulled into the driveway. I have been quoting the module on every panel since then and nobody has pushed back yet. Now I am second guessing my whole stance on the cheap off brand modules versus the ones the big makers ship, has anyone run both and seen a real difference in how they hold a signal in a bad spot?
