I install Home Automation with security and camera's. I set up my clients smart phones to access and control their homes from remote. From time to time the IP address changes or if the modem is powered down we usually get a new IP. Telus will only offer Static Ip's to business, not their residential clients. My 1st option is to find a service that will track a IP if it changes for free or pay but their is a lag in tracking sometimes, 2nd option is to advise my clients to join a provider that can offer static IP. This security home automation is becoming a big market and Telus is missing Out!
