Grandstream GDS3725 Smart IP Video Door Station with 4MP Camera & Keypad

The Grandstream GDS3725 Smart IP Video Door Station combines an IP intercom, HD surveillance camera, and secure access controller into a single, weatherproof unit. Designed for commercial buildings, schools, warehouses, and gated facilities, it gives you clear video of every visitor while tightly controlling who can unlock the door.

A 4MP HDR image sensor and AI-powered image processing deliver crisp 1080p full HD video and a wide 127° horizontal field of view, so you can identify people and objects even in challenging lighting. Built-in white LEDs provide intelligent fill light for low-light scenes, while PIR detection monitors motion within roughly 10–16 feet (3–5 m).

The GDS3725’s metal housing is IP66 weather-rated and IK10 vandal resistant, making it suitable for exposed outdoor installations and high-traffic areas. A numeric keypad and multi-technology IC/ID card reader support flexible access methods, from PIN codes to key cards and NFC credentials. Solid State Relay (SSR) outputs help protect against tampering and external magnetic interference.

Thanks to built-in dual microphones, a 3W speaker, and AI-based noise reduction, visitors and staff can communicate clearly, even in noisy environments. The unit speaks standard SIP, so it integrates with IP PBXs, video phones, and paging systems, and it’s compatible with Grandstream’s GSC357x intercom stations, GXV video phones, Wave Mobile App, and GNS network storage for a complete end-to-end solution.

Management is handled through Grandstream’s SecureAccess mobile app and GDS Manager software, which let you configure users, PINs, card permissions, and remote door-opening options, plus review logs and event snapshots from anywhere.
