Hikvision DS-2DF7A436IXG-EL(Y) — 4MP 36× DarkFighter 2.0 PTZ Network Speed Dome with 300 m IR (NEMA 4X Anti-Corrosion)
The Hikvision DS-2DF7A436IXG-EL(Y) is the IR-equipped flagship of Hikvision's 7A Ultra-Series PTZ line — a 4MP outdoor pan/tilt/zoom speed dome that pairs a 1/1.8" progressive-scan CMOS sensor and a 36× motorised optical zoom (6.0–216 mm · F1.2) with a built-in IR illuminator out to 300 m. DarkFighter 2.0 sensor technology, 150 dB AWDR, Smart Pan-Tilt Correction and a built-in gyroscope EIS round out the imaging chain. The -Y suffix on this Australian-stocked SKU denotes Hikvision's moderate anti-corrosion housing — NEMA 4X-rated for coastal Australian sites within roughly 2 km of the shoreline and for areas exposed to acid rain. The base DS-2DF7A436IXG-EL (no -Y) ships with no specific corrosion protection; we stock the -Y variant by default.
This is the camera Hikvision builds for completely dark long-range surveillance — rural property boundaries with no street lighting, dark mining haul roads, unlit perimeter walls, river and forest monitoring at scenic spots, unlit rail-yard aprons, scenic-spot and large-venue overwatch. The IR LED array adds 300 m of reliable illumination at full telephoto zoom, while the DarkFighter 2.0 sensor takes over at any time the scene has even modest ambient light. PTZ kinematics are tuned for incident response: 360° continuous pan at up to 550°/s (700°/s max), tilt −20° to +90° auto-flip, 300 presets, 8 patrol routes and 3D click-to-frame positioning. Powered by PoE 802.3bt Type 4 Class 8 (90 W class) or 36 VDC, with built-in heater and demist. Cyber-hardened with TPM 2.0 (FIPS 140-2 Level 2). Australian stock, 3-year Australian warranty.

Why Choose the 7A IR PTZ over the 6A
Both the 6A and 7A Ultra-Series PTZs share the same 1/1.8" DarkFighter 2.0 sensor, the same 36× optical zoom, the same 150 dB AWDR and the same on-camera deep-learning AI stack. The deciding question is how dark the scene actually gets at the far end of the zoom range. The 7A's built-in 300 m IR illuminator is the difference-maker: it lights an entire perimeter wall, dark haul road or rural property boundary at full telephoto, in zero ambient light. If the scene has streetlights, dock lighting or moonlight, the 6A's DarkFighter 2.0 alone is enough. If the scene is genuinely dark, the 7A is what gets the shot.
300 m IR — Zero-Light Identification
Smart IR illumination out to 300 m at 850 nm wavelength. The IR LED array is matched to the 36× zoom optics — at telephoto, the beam tightens with the zoom to keep target illumination consistent across the working range.
36× Optical Zoom · F1.2 · 6–216 mm
The same long-zoom lens as the 6A — but here paired with the IR ring for completely dark scenes. Identify at 297.9 m tele (EN 62676-4), recognise at 595.9 m, detect to 2,979 m.
DarkFighter 2.0 + 150 dB AWDR
Same sensor and same wide-dynamic-range as the 6A — 0.0003 lux colour, 0.0001 lux monochrome, 150 dB AWDR. At dawn / dusk / mixed lighting the camera produces colour and switches to IR-aided monochrome only when needed.
550°/s Pan · 300°/s Tilt
Pan preset speed up to 550°/s (max 700°/s), tilt to 300°/s. Faster than the 6A's 300°/s — important for incident response on big sites where the camera has to swing from one preset to a diagonally-opposite one in well under a second.
Smart Pan-Tilt Correction + Gyroscope EIS
Smart Pan-Tilt Correction automatically compensates for mechanical drift over time, keeping presets accurate to the original setpoint. Combined with the built-in gyroscope EIS, the image stays steady on tall pole mounts in coastal wind.
Lighter, Smaller, IR-Equipped
At 5 kg and ⌀ 215 × 297 mm, the 7A is actually smaller and lighter than the 6A (6 kg / ⌀ 231 × 356 mm) despite adding the IR LED ring — Hikvision re-engineered the optical assembly to gain the IR without growing the camera body.
Important Install Note — PoE 802.3bt Class 8 (90 W) or 36 VDC
The 7A IR PTZ does not run on standard PoE+ (802.3at, 25.5 W) or even Hi-PoE 60 W. Total camera power draw with the IR LED ring and heater active is up to 90 W on either 36 VDC or PoE 802.3bt Type 4 Class 8 — the camera reserves 6.4 W for IR, 8 W for the heater and 52 W for the camera body. Standardise on one of the following:
-
PoE 802.3bt Type 4 Class 8 injector or switch on the camera's network run — provides the full 90 W via single Cat 6 cable, the simplest install.
-
36 VDC dedicated supply at the camera — used where you're running fibre to the camera or where you prefer to feed power separately from the data drop.
Standard PoE+ switches (15 W or 25.5 W class) will not reliably power this camera, especially when the IR ring and heater are both active in cold weather. Contact our Australian team for the right 90 W PoE++ injector or 36 VDC supply for your install.
On-Camera Deep-Learning AI
The 7A PTZ runs Hikvision's deep-learning engine on the camera itself, classifying objects and triggering only on the targets that matter. The full AI stack is identical to the 6A sibling — the 7A's value-add is purely the IR illuminator for dark scenes.
Perimeter Protection
Line crossing, region entrance, intrusion and region exiting detection — each filtered by target type (human / vehicle) to suppress nuisance alarms from rain, foliage, animals and headlight glare.
Multi-Target-Type Detection
Simultaneous detection across three target classes with rich feature extraction: face (7 features), human (14 features) and vehicle (8 features). Feeds searchable metadata into your NVR for fast post-incident review.
Face Capture — 30 Simultaneous
Detects up to 30 faces in frame, grades face quality, and uploads the best frame plus context. Useful at port gates, mining-camp entry points and large-venue access control.
Face Comparison — 150,000 Total
10 face libraries × 30,000 faces = 150,000 total with encrypted on-camera storage — enterprise-scale watchlist comparison without a separate face server.
Smart Tracking 3.0 — Auto-Follow
Locks onto detected human or vehicle targets and pans / tilts / zooms automatically to keep them framed. Person arming mode flags specific faces or human IDs that trigger alarms plus tracking when detected.
Audio & Behaviour Events
Audio exception detection, video tampering, vandal-proof alarm, scene change, unattended baggage and object removal detection — useful for unmanned dock aprons, rail-yard sidings and large-venue overwatch.
Pan / Tilt / Zoom — Faster Kinematics for Incident Response
360° Continuous Pan · 550°/s Preset
360° continuous pan with preset speed up to 550°/s (max 700°/s) — the camera moves from a preset on one side of the site to the opposite-side preset in well under a second.
Tilt −20° to +90° · Auto-Flip
Tilt range from −20° (below horizon, useful for tall-pole overviews of the ground below) to +90° with auto-flip support for tracking a target straight under the dome.
300 Presets · 8 Patrols
300 presets per camera, 8 patrol routes with up to 32 presets each. Schedule the camera to walk a perimeter route automatically every shift change.
3D Positioning · Power-Off Memory
Click any target on the live image to centre-frame and zoom in one motion. Power-off memory returns the camera to its previous orientation after a brown-out.
Smart Pan-Tilt Correction
The PTZ self-corrects mechanical drift over time, keeping presets accurate to their original setpoint without manual re-calibration.
Built-in Gyroscope EIS
The gyroscope drives electronic image stabilisation — critical for tall pole installs in coastal wind, where mount vibration would otherwise blur the image and confuse the AI engine.

DS-2DF7A436IXG-EL(Y) vs DS-2DF6A436XG1-EL(Y) — Built-in IR or Ambient-Light Only?
The 6A and 7A Ultra-Series PTZs are essentially the same camera with one decisive difference: the 7A has a built-in 300 m IR illuminator; the 6A does not. Everything else — sensor, zoom, WDR, low-light spec, deep-learning AI, face capture, face comparison, auto-tracking, IP/IK protection, cyber-security baseline — is essentially identical. The 7A is also faster (550°/s pan vs 300°/s on the 6A) and surprisingly lighter (5 kg vs 6 kg). The cost of the IR ring is more power — the 7A needs PoE 802.3bt Class 8 (90 W) vs the 6A's Hi-PoE (60 W class).

PoE 802.3bt Class 8 (90 W) Injector / Switch
Required if you're not powering the camera from a separate 36 VDC supply. Make sure the injector or switch is genuinely Type 4 Class 8 (90 W) — standard PoE+ (25.5 W) and Hi-PoE (60 W) will not reliably power this camera with IR active. Contact our Australian team for the right injector.
Frequently Asked Questions
What does the "-Y" suffix mean and which variant do you stock?
The -Y suffix indicates Hikvision's moderate anti-corrosion housing — NEMA 4X-rated, designed for coastal Australian sites within ~2 km of the shoreline and areas affected by acid rain. We stock the DS-2DF7A436IXG-ELY (with -Y) as our Australian default. The base DS-2DF7A436IXG-EL (no -Y) has "no specific anti-corrosion protection" per the datasheet — we don't stock it.
How does the 300 m IR work — does it light the full 300 m at wide-angle?
The IR illumination range scales with the zoom. At full telephoto, the IR beam tightens and reaches up to 300 m with the smart-IR supplement adjusting intensity to avoid over-exposing close-range targets. At wide-angle, the beam spreads to cover the wider field of view at a shorter effective distance. The combination keeps target illumination consistent across the zoom range.
Why doesn't it run on standard PoE+ or Hi-PoE?
Total camera power draw with the IR LED ring and heater active is up to 90 W. Standard PoE+ (IEEE 802.3at) tops out at 25.5 W, and Hi-PoE (60 W class) doesn't have the headroom for the IR ring at full output. The camera requires PoE 802.3bt Type 4 Class 8 (90 W) or a dedicated 36 VDC supply.
Should I buy the 7A or the 6A sibling?
If the scene has any reasonable ambient lighting at night (streetlights, dock lights, security floodlights, mast lighting, moonlight) the 6A's DarkFighter 2.0 sensor alone is enough — and you'll save on the 90 W power chain. Choose the 7A specifically for genuinely dark long-range sites: rural property boundaries, dark mining haul roads, unlit power-station yards, scenic-spot and river overwatch. Compare side-by-side: DS-2DF6A436XG1-EL(Y) →
Does it support number-plate recognition (ANPR)?
This is not marketed as an ANPR camera. The 7A PTZ is built for long-range surveillance, perimeter protection and auto-tracking. For on-camera number-plate recognition, choose a dedicated DeepinView ANPR bullet — for example the iDS-2CD7A46G2/P-IZHSY with its purpose-built LPR engine and 10,000-record plate database.
How far away can the camera identify a target?
Per EN 62676-4 criteria at full telephoto: Detect 2,979 m · Observe 1,182 m · Recognise 596 m · Identify 297.9 m. "Identify" means the image is detailed enough to recognise a specific individual — that's a usable working distance for almost any large-site security application. Detection extends nearly 3 km.
How does Smart Pan-Tilt Correction work?
Over thousands of pan/tilt cycles, mechanical drift can shift preset positions by a few degrees from their original setpoints. Smart Pan-Tilt Correction measures and compensates for that drift automatically, keeping all presets accurate to the original setpoint without manual re-calibration — important for unmanned sites where a technician can't easily re-set presets in person.
Is this NDAA Section 889 compliant?
No. Hikvision is subject to NDAA Section 889 restrictions in the United States. For NDAA-compliant long-range PTZ projects (typically US federally-funded), we stock alternative brands — please contact our team for a recommendation. For Australian commercial, council, port-authority, private and most state-government projects without an NDAA contractual requirement, this camera is freely usable.
Will the camera record locally if the NVR drops?
Yes. microSD up to 1 TB — when the network link to the NVR drops, the camera continues writing locally and the footage is available for retrieval once the link returns.
What's the warranty and where is it serviced?
This camera ships with a 3-year Australian Hikvision warranty, serviced back-to-base through Hikvision Australia. CCTV Guru manages the entire RA process from our Sydney office and provides Australian-based pre-sales and technical support for the life of the product.
Do you ship Australia-wide and is stock genuine?
Yes — Australian stock from authorised Hikvision Australia channels (not parallel imports). We ship Australia-wide every business day with same-day dispatch on orders placed before 2 pm AEST to Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra, Darwin and regional addresses.
