Access to the enclosure is requested when the user swipes the access card using the card reader. The system communicates to the back office, where the back-end software verifies whether the user is authorised to access the enclosure at the requested time. If yes, the device emits a short beep and the front panel door unlocks, allowing access. If access is denied, then a long beep is emitted, and access is denied. The rear door is unlocked via a push button from the front, which releases the rear lock if and only if, the user has authorisation for rear access.

 

All events are logged onto the back-end software and on the memory of the device. The memory operates on First-In First-Out (FIFO) queue and old data is replaced by the latest access information. If any of the doors remain open, the door switches will report the event as the switches are wired in series.

 

A further ground-breaking technology development by our engineering team, both local and abroad.

 

Vixnet has given their customers the benefit now via a downloadable app to measure the precise signal strength by identifying the number of high sites receiving the transmitted signal, and at what dB.

 

This is a powerful tool to be used for management reporting as well as assisting the technician on site to position the radio to its optimum efficiency and ensuring redundancy by multiple base station reception.
