§ 01Overview
What the DS-2DF8C435MHS-DELW is
The Hikvision DS-2DF8C435MHS-DELW is a flagship 4 MP Ultra-series PTZ built around DarkFighterX, a dual-sensor design that combines two 1/1.8" sensors to deliver clearer, more colourful images in extremely low light than a single sensor can manage.
Paired with a 35x optical zoom (5.9 to 206.5 mm), it is made for the hardest long-range jobs: airports, ports, large industrial sites and major infrastructure where you need to see a long way in poor light.
It is a deep-learning camera with on-board analytics.
It detects and classifies people and vehicles, runs perimeter rules such as line crossing and intrusion, reads vehicle details, and supports auto-tracking that locks onto a target and follows it across the scene.
A built-in gyroscope assists electronic image stabilisation to steady the magnified image on a high mast.
Its supplement light is hybrid, combining infrared and white light up to 300 m; DarkFighterX holds colour in low light, but at long range in darkness the camera relies on infrared, so the far night image is black and white.
This is a metal speed dome rated IP67 and IK10 with TVS surge protection, optical defog and a wide operating temperature range, built for continuous outdoor duty.
It is powered by Hi-PoE or 36 VDC, well above standard PoE, so check your switch, injector or recorder can supply it.
Audio is via a line-in and line-out for external devices rather than a built-in microphone.
Record it to a Hikvision NVR that supports the AI metadata and the bandwidth of a high-end PTZ.

§ 06Setup
Installation & setup
What's in the box
One DS-2DF8C435MHS-DELW PTZ speed dome with mounting hardware and a quick guide. The Hi-PoE source or 36 VDC supply, network cable, microSD card and any pole or wall bracket are supplied separately.
Installation requirements
Mount it high on a pole or mast with a clear, unobstructed view for the long zoom, and power it with Hi-PoE or 36 VDC from a capable switch, injector or NVR. Set the presets, patrols, auto-tracking and AI rules in the software, and record it to a Hikvision NVR that supports the AI metadata and PTZ bandwidth.

§ 09Bundles
Recommended packages
Record and review it
Feed it to a Hikvision AcuSense recorder such as the 16-channel DS-7732NXI-I4/16P NVR for larger sites, or the 8-channel DS-7608NI-I2/8P for smaller ones. Add a surveillance-grade drive like the 8 TB for weeks of continuous footage.
Power a Hi-PoE PTZ
This PTZ needs Hi-PoE or 36 VDC, well above standard PoE. Use a Hi-PoE port on the recorder, a dedicated Hi-PoE injector, or the supplied power adaptor.
Step down the zoom range
If 35x is more reach than you need, the 36x DS-2DF7A436IXG-EL PTZ offers similar deep-learning tracking, while the smaller 25x mini PTZ suits closer sites.
