Grandstream GDS3725 Smart Door Station, 4MP, IK10

The Grandstream GDS3725 video door station pairs a 4-megapixel Ultra HD sensor with AI-assisted motion detection and a dual-frequency 13.56MHz/125kHz card reader, built into a metal enclosure rated IK10 for sites where physical durability matters as much as image quality. The wide FOV127°(H) x 70°(V) x 152°(D) lens and wide dynamic range up to 120dB cover a doorway end to end even against strong backlighting, while a 15-key numeric keypad adds PIN-based entry alongside card access. Power comes from PoE (802.3af Class 3) or a wide-range DC 9-36V input, and Bluetooth 5.0 supports app-based door release without adding Wi-Fi to the door’s network exposure, alongside a PIR motion sensor with a 3 to 5 meter detection range that wakes the camera before a visitor reaches the door. Within the GDS37 family, the GDS3725 is the metal-cased, wired-first sibling to the GDS3727, trading Wi-Fi for a tougher IK10 shell and a broader set of access-control outputs.

Grandstream GDS3725 video door station in practice

Video streams over H.264 at up to 1920×1080 at 30fps, with two microphones and a 3-watt speaker carrying G.711, G.722, G.726-32, and G.729 voice codecs, keeping a call intelligible even at a noisy site entrance. The card reader accepts MIFARE Classic 1K/4K, Ultralight, PLUS, and DESFire formats for up to 5,000 IDs, enough headroom to manage a large staff roster or residential population without running out of reader capacity. The unit provides two solid-state relay access-control outputs, three alarm inputs and two alarm outputs, and RS485 plus Wiegand 26/34 expansion for wiring into an existing access-control panel, alongside an SD card slot supporting up to 256GB of local storage. Security runs on Ed25519/X25519 with 256-bit AES encryption and TLS, SRTP, and HTTPS, with remote firmware updates over TFTP, HTTP, HTTPS, or TR-069, and ONVIF Profile S support for pulling the video stream into a third-party video management system.

Where it fits on a Saudi site

A metal door station rated IK10 suits entrances at higher risk of tampering, such as factory or warehouse gates, public parking entries, and large residential compound entrances, where a security team needs to verify a visitor both visually and by card. The -30°C to 60°C operating range and -30°C to 70°C storage range, with 10-90% non-condensing humidity tolerance, suit an uncovered outdoor mount through a Saudi summer. The absence of Wi-Fi on this model means relying on wired power through PoE or DC input, a deliberate choice for a site that prefers not to add a wireless access point to the door’s network footprint.

Positioning against the GDS3727 and the rest of the family

The GDS3725 and GDS3727 share the same 4-megapixel sensor, lens, dual-frequency card reader, and AI features, but the practical differences run deep: the GDS3725 carries a metal casing, IK10 rating, two relay outputs, and Wiegand expansion, while the GDS3727 uses a plastic casing with a lower impact rating and a single relay output with no Wiegand, in exchange for built-in dual-band Wi-Fi the GDS3725 does not have. Against the GDS3710 and GDS3712, which carry a lower-resolution sensor and a single-frequency 125kHz reader, the GDS3725 offers higher image resolution and far greater identity-management capacity. The GDS3702, the only camera-free model in the family, sits at the opposite end of the range from the GDS3725’s full visual and card-based feature set.

Deployment notes

The unit measures 204 x 87 x 35.5 mm and weighs 1.56 kg, with a package weight of 1.743 kg, heavier than the rest of the family because of its metal body. It ships with a quick installation guide, a wall mounting bracket, an IC card, and a rain cover in the box, enough for a standard installation without buying extra accessories. The unit carries FCC, CE, RCM, and IC compliance markings alongside independent IP66 and IK10 ratings, which makes it straightforward to specify on projects that require formal compliance documentation for imported equipment.
