Hikvision DS-2DF7A436IXG-EL 4MP 36× IR Network Speed Dome (Ultra Series)

The Hikvision DS-2DF7A436IXG-EL is a professional-grade Ultra Series PTZ speed dome built for large-area, mission-critical surveillance. Its 1/1.8″ progressive scan CMOS sensor delivers 4 MP resolution (2688 × 1520) with exceptional clarity, even in near darkness.

With a 36× optical zoom lens (6.0 mm – 216 mm) and 16× digital zoom, the camera can capture close-up details at long range while maintaining image sharpness. Featuring DarkFighter 2.0 technology, it performs exceptionally in low-light environments with a color sensitivity of just 0.0003 lux.

The 150 dB Adaptive Wide Dynamic Range (AWDR) ensures clear images in scenes with strong backlighting, while built-in image stabilization and gyro-assisted correction keep footage smooth during zoom or vibration. The DS-2DF7A436IXG-EL is built for durability, with IP67 and IK10 ratings, an operational temperature range of –40 °C to +70 °C, and optional NEMA 4X corrosion protection for harsh coastal or industrial conditions.

This camera is the ideal choice for airports, seaports, rail terminals, and infrastructure sites that demand high zoom power, intelligent analytics, and all-weather reliability.

Installer Notes

• Mounting: Use a rated Ultra Series wall or pole bracket designed for this PTZ model. Mount securely to a structure that can handle the camera’s weight and pan/tilt torque.

• Power Requirements: This camera requires Hi-PoE or 36 V DC with up to 45 W draw when heater is active. Confirm power supply and cable length for stable operation.

• Networking: Use outdoor-rated Cat6 or higher cabling. Add surge protection and grounding for elevated or long cable runs.

• Environmental Setup: Verify all cable glands and junction boxes maintain IP67 integrity. For coastal or corrosive environments, enable NEMA 4X protection.

• Configuration: After installation, perform lens calibration, preset programming, and patrol path setup for automated surveillance.

• Focus & Tracking: Utilize auto-focus and smart-tracking for large area coverage. Fine-tune zoom speeds to minimize image blur at full telephoto range.

• Firmware & Security: Update to the latest firmware before deployment. Enable HTTPS, disable unused protocols, and change all default credentials.

• Maintenance: Inspect lens and housing regularly. Clean using soft, non-abrasive materials only. Test PTZ motion, focus, and IR functionality at least every six months.
