| The Hikvision DS‑TMG421‑L/R 2+2 m model features a dual-curved aluminum boom design (each arm 2 m), providing extra coverage while maintaining compact operation. Ideal for dual-lane or wide-lane entries, this model opens/closes in about 3 seconds, making it suitable for commercial buildings, residential complexes, or mixed-use spaces.
It is powered by a high-efficiency brushless DC motor, rated for over 5 million operation cycles. Enhanced safety mechanisms include anti-fall sensors (IR and radar), obstacle detection with automatic rebound, and a nixie tube fault display system. Its side-mountable design optimizes installation flexibility, especially in constrained spaces. Manual control is available through a built-in handwheel for power outages. Rated IP54 and operable from -30°C to +60°C, it supports remote operation, LED indicator boom integration, and compatibility with fire alarm triggers. Its combination of folding-arm versatility and rugged reliability makes the DS‑TMG421 perfect for dynamic security applications. |
