Is that everything you need or do you have to buy additional pieces to make it work?
This is just the receiver, you will need to buy the Rodann Driveway Alarm with Counter: https://www.guardlinesecurity.com/products/rodann-1000-ft-driveway-alarm-with-alert-counter
is there a product you can add to this device to send email or tex messages to you cell phone telling you someone has trip your alarm
Unfortunately, this system does not support such a feature. I would recommend the Guardline Driveway Alarm, as the dry contacts on the receiver can be used in conjunction with a WiFi contact sensor to do what you are asking.
