The EnvisaLink™ EVL4 module is a powerful TCP-IP based, bus-level interface to DSC PowerSeries* panels and Honeywell Vista* panels. It allows you to view the status of and even control your alarm panel through a standard web-browser or smart-phone.
Because the EnvisaLink™ EVL4 is an Internet based security device, you no longer need a phone line for your security system to send alarms to the central station or alerts to you or your contact's smartphone.
