Surveillance Camera Dahua SD22404DB-GNY-W 4MP 4x Starlight

The Dahua SD22404DB-GNY-W is a 4MP Starlight PTZ network surveillance camera designed for indoor and outdoor monitoring. It features a 1/2.8" CMOS sensor, maximum resolution of 2560×1440, 4× optical zoom with a 2.8–12 mm varifocal lens and Starlight technology for improved low-light performance. The unit supports three video streams, multiple compression formats (including H.265 and Smart H.265+), Wi‑Fi connectivity, and ONVIF interoperability for integration with third-party recorders and management systems.

Advantages

This camera provides high-resolution 4MP imagery and versatile PTZ control (pan 0°–355°, tilt 0°–90°) with fast preset speeds and up to 300 presets. Starlight sensor sensitivity and electronic image stabilization enable clearer night and low-light footage. Built-in intelligent functions include perimeter IVS, face detection and classification (people/vehicle), SMD, and multiple alarm linkage options. Durable IP66 and IK10 ratings make the housing suitable for outdoor deployment.

Suitable for

• Perimeter and area surveillance for commercial properties
• Parking lots and vehicle monitoring
• Public spaces and campuses requiring pan-tilt-zoom coverage
• Indoor large-area monitoring such as warehouses and halls

How to use

Mount the camera on a stable surface or bracket suitable for outdoor use, provide a 12 VDC power supply and connect to the network via RJ‑45 or configure the 2.4 GHz Wi‑Fi. Use the Dahua management software (DSS/DMSS) or an ONVIF‑compatible NVR to perform initial setup: adjust focus and zoom, set presets and tours, configure video streams and recording storage (Micro SD/FTP/NAS), and enable intelligent detection rules such as tripwire and intrusion. For face detection and capture settings, select the desired capture strategy (real‑time or quality first) in the camera's interface.

Usage recommendations

Position the camera to cover the widest required area while keeping key detection zones within optimal DORI distances (Detect 240 m, Observe 94.8 m, Recognize 48 m, Identify 24 m). For reliable night performance, keep the lens clean and avoid strong backlighting; enable electronic stabilization and DWDR to improve image clarity under varying lighting conditions.
