BI has different alerts already built in. Go to camera properties > "Send push notification to mobile app", then change the Notification Sound. I find the push notifications are more real time than the SMS text message. I know exactly which cam is alerting just by the different notification sounds. I also use the SMS option and set the quality down to about 10 - 20% so when in poor cell coverage areas, there is not much data to send. There is still enough resolution for you to see what is happening with the sent image.
