Hikvision DS-TMG421

The Hikvision DS-TMG421 42 Series Folding-Pole Barrier Gate is designed for controlled vehicle entrances where ceiling height or overhead clearance makes a conventional straight boom difficult to use, such as basement parking areas, residential towers, hotels, offices and commercial car parks. It uses an SGCC steel housing, an integrated machine core with hardened carbon-steel gearing and a low-noise DC brushless motor with variable-frequency control for smooth acceleration and deceleration. The DS-TMG421 supports folding boom configurations including approximately 1.5 + 1.5 m, 2 + 2 m and 2.5 + 2.5 m, with the 42-Series documentation specifying opening/closing times from roughly 2.1 seconds to 5 seconds depending on boom length. Its safety and management functions include obstacle rebound, opening priority, event logging, fault-code diagnostics, delayed automatic closing, manual hand-wheel opening during power loss, and multiple anti-fall methods using infrared sensors, vehicle detectors or radar. Optional supercapacitor components can automatically raise the boom during a power outage. The platform is designed for intensive operation with a DC brushless motor, 100% duty cycle and approximately 5 million cycles, making it suitable for demanding parking applications throughout the Middle East. The related DS-TMG421/B is the enhanced folding-boom version with an integrated red/green body-status indicator. Hikvision’s current datasheet specifies a 2 + 2 m folding pole, approximately 3-second rising and falling time, 220 VAC supply, IP54-class barrier architecture, RS-485 communication, open/close/stop inputs, limit outputs, traffic-light control and an input for IR sensors, vehicle detectors or radar. It retains the 5-million-cycle brushless-motor architecture, obstacle rebound, opening priority, fault-code display and optional automatic boom raising during power failure. For projects where overhead folding is unnecessary but enhanced visibility is required, the related DS-TMG420/A/B uses a straight illuminated boom available in 3 m and 4 m versions. Its AL6061 aluminium boom incorporates an LED strip that displays green when the barrier is open and red in other operating states, while the cabinet also provides green-arrow/red-prohibition indication. The broader DS-TMG420 platform supports brushless operation, approximately 1.8-second movement with a 3 m boom and 2.5 seconds with a 4 m boom, 5-million-cycle durability, anti-fall integration and optional power-off opening. In practical terms, DS-TMG421 suits height-restricted entrances, DS-TMG421/B adds clear cabinet-level status indication, and DS-TMG420/A/B is ideal for standard-height entrances requiring a highly visible illuminated straight boom. As a Hikvision partner and system integrator serving the Middle East, VEGA Digital IT Solutions LLC can provide complete DS-TMG421-family implementation, including site survey, basement-clearance measurement, lane-width and folding-boom selection, concrete foundation preparation, barrier anchoring, mains power and low-voltage control cabling, boom assembly, balancing and final parameter configuration. VEGA Digital can integrate the barrier with Hikvision ANPR/LPR cameras, UHF long-range vehicle readers, loop detectors, anti-fall radar, infrared safety sensors, intercom systems, access controllers, visitor-management platforms and parking-management software, configuring opening priority, delayed closing, obstacle rebound, vehicle-presence logic and body/boom LED indications where supported. Final commissioning can include folding-boom geometry and ceiling-clearance checks, radar or loop calibration, opening/closing timing, emergency/manual operation, RS-485 and control-interface testing, ANPR/RFID authorization and end-user training, providing a complete Hikvision vehicle-access and parking-management solution for basement parking, residential towers, hotels, offices, commercial developments and industrial facilities across Dubai, the UAE and the wider Middle East.
