Hikvision DS-TMG012-4

The Hikvision DS-TMG012-4 (often categorized within the TMG4BX-A series) is a professional Wireless Barrier Gate Remote Controller Key-Fob.

Designed as a mobile access management accessory for Hikvision's automated parking lot boom barriers and vehicle entrance systems, it provides security personnel, facility managers, or residents with a secure way to operate entry and exit gates from a distance.

Key Technical Specifications
