Secure Access from a Distance

Do you have a location where you would like to have keyless or secure entry that is too far away from your access system controller to cost justify the expense of installation. If so, a recent introduction by Sure-Fi might just be the answer:

The wireless wiegand bridge by Sure-Fi is a wireless adapter that works for any wiegand protocol. The Sure-Fi wireless bridge has a range of up to 1 mile through obstructions and up to 50 miles line-of-sight. With one wiegand input, two relay outputs, one Request-to-Exit input and one auxiliary input this bridge is a fit for almost every application.

The Sure-Fi Wiegand Bridge System consists of two units: The Controller Interface, and the Remote Interface. The system provides a wireless connection (bridge) from a remote location, such as at a door, to the controller location at the access control panel. The Controller Interface connects with the access control panel and communicates wirelessly to the Remote Interface, which is placed near any peripheral Wiegand device (card reader / keypad / receiver /etc). Each Bridge System consists of one Wiegand input, two relay outputs and inputs for door monitor sensors/request to exit inputs. The Sure-Fi App provides troubleshooting, diagnostics information, and field upgrades.
