Grandstream GSC cameras are automatically detected and configured. Plug them into the network, and the GVR assigns IP settings and begins recording — no manual setup required.
Set custom motion zones and sensitivity levels. Receive instant email alerts with snapshots, or push notifications to your phone when unexpected activity occurs.
Every channel records in Full HD with smooth 30fps. Crystal‑clear footage ensures you capture every detail — from license plates to facial features.
Connect microphones to cameras and record audio along with video. Two‑way audio support allows you to speak through the camera from the monitoring station or smartphone.
ONVIF Profile S compliance ensures compatibility with a wide range of third‑party IP cameras. You're not locked into a single brand — the GVR works with existing camera investments.
The local GUI, accessible via HDMI/VGA, and the web client are designed for simplicity. Drag‑and‑drop camera layouts, calendar‑based playback, and intuitive search make daily operation effortless.
Built‑in PoE on the GVR3520 reduces cabling and switch costs. Dual NICs on the larger models allow separate camera and management networks, or failover for redundancy.
Support for large HDDs and RAID configurations (GVR3552) means your footage is safe from disk failures. Smart playback and timeline views help locate incidents in seconds.
Grandstream GVR Series network video recorders deliver professional‑grade IP video recording with zero complexity. Purpose‑built for small‑to‑medium installations, they combine plug‑and‑play camera discovery, robust 1080p recording, and a user interface that anyone can master in minutes.
The Right Model for Your Scale: The GVR3520 supports up to 16 cameras and includes 8 PoE ports, making it a perfect all‑in‑one solution for a small shop, single‑floor office, or home. The GVR3550 scales to 64 cameras without PoE, ideal for multi‑floor buildings or campus deployments. The flagship GVR3552 adds RAID redundancy for mission‑critical environments like banks, hospitals, or large warehouses where data integrity is non‑negotiable.
Instant Setup, Instant Security: Grandstream GSC cameras are auto‑discovered the moment they connect. The GVR assigns IPs, configures recording parameters, and starts saving footage to the internal HDD. For third‑party cameras, the ONVIF‑compatible interface adds them with a few clicks. There's no need for a dedicated monitoring PC — simply connect a monitor via HDMI and control everything with a mouse.
Stay Informed Anywhere: The free GView mobile app for iOS and Android turns your smartphone into a portable monitoring center. Live view, playback, and motion alerts are always at hand. For larger operations, GSURF Pro VMS provides centralised multi‑site management.
