Office Upgrade: Total replacement of security cameras (8 units) added to the upgrade of the security system to cellular call system to bypass the VOIP phone system. issues with the burglary in my area for the last few months. Now I can check on my phone and receive notices of login and out and remote set too.

Well after 25 years of using Security One I made a decision to terminate my service with them after the panel going off after midnight chirping and waking me up. Come to find out the cellular equipment is 3G and that is being phased out. Here is the kicker to install a 4G it will cost $300 and Security One is so gracious to flip the cost. Well in my book they want me as a customer that's a cost of doing business and someone in the company didn't make a wise business decision a few years ago when I went to cell service on my alarm.

This must have been seen coming. Told SO that I refused to pay the $150 and after reading my contract that it was time to go. They did this a few years ago when I went to the cellular service. Sign a new contract for 3 years. Lord I have been a loyal customer for 25 years. Well I installed the Ring Alarm yesterday and the monthly fee is $10. That includes back up cell service if the internet goes down. That beats a 10% increase as allowed in my contract to $37 a month. So far I like it has a camera with cloud storage included.

Security One has taken care of my home security system services for over six years now. I am extremely pleased with the service. All of my encounters with the company have been great. I highly recommend their services.
