The IPC6624SR-X33-VD2 is a 4MP intelligent network PTZ camera with 33× optical / 8× digital zoom (4.5–148.5 mm, F1.5–F4.0) and Wise-ISP low-light processing, backed by 120 dB true WDR and >56 dB S/N for high-contrast outdoor scenes. UNV LM-Auto Tracking accurately identifies and continuously tracks motor vehicles, non-motor vehicles and pedestrians — even through occlusion, multi-target crossing or high-speed motion — while Smart Intrusion Prevention covers cross-line, enter-area, leave-area and intrusion detection with classification-based false-alarm filtering, plus people-flow counting and crowd-density detection. IR illumination reaches 200 m, heatwave reduction and adaptive defog keep long-zoom images clear outdoors, and the IP67 / IK10 housing runs from -40 °C to 70 °C on DC 24 V, AC 24 V or PoE (IEEE 802.3at).
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shopping malls & commercial complexes33× zoom covers a wide atrium or car-park entrance from one pole and still reads a distant storefront; UNV LM-Auto Tracking follows a loitering or fast-moving subject across the plaza, and people counting / crowd density feed footfall analytics for mall operations.
Parking structures & entrancesAuto tracking classifies and follows vehicles as they enter, while adaptive highlight compensation (HLC) tames headlight glare at night so plates and faces near the barrier stay readable.
Perimeter & rooftop protectionSmart Intrusion Prevention covers cross-line, enter-area, leave-area and intrusion detection with false-alarm filtering by classifying human, non-motor vehicle and vehicle targets.
Open plazas & event spaces360° endless pan plus people-flow counting and crowd-density detection help operators watch attendance and spot congestion during busy events.
Long approach roads, night200 m IR illumination plus 33× telephoto reach targets far down an approach road; heatwave reduction and adaptive defog keep the long-zoom image usable in haze or summer heat shimmer.
Harsh-climate installationsIP67 sealing, IK10 vandal resistance, -40 °C to 70 °C operation and 6 kV surge protection, with the flexibility to run on DC 24 V, AC 24 V or PoE (IEEE 802.3at) depending on what's already at the pole.
Not the right pick if you need…
- No fixed 360° panorama overview channel — this is a single classic PTZ head. If you need a fixed wide overview running alongside the zoom detail, choose a panoramic-linkage model instead.
- If using PoE, it must be IEEE 802.3at (PoE+) to cover the max 20.90 W draw — a basic 802.3af (15.4 W) injector or switch port is not enough; otherwise plan DC 24 V or AC 24 V power instead.
- No official dimensional drawing was published for this model — only the text figures (Ø227 mm × 390 mm, 5.21 kg) are available; request a drawing from us before finalizing bracket or enclosure cutouts.
- No accessories list is published on this datasheet — confirm mounting bracket compatibility with us before ordering.

How wide a view at each distance
Scene width covered at typical mounting distances — the number you need to work out how many cameras a wall, yard or aisle takes.
| Distance | 53.6° wide | 2.7° tele |
|---|---|---|
| 5 m16 ft | 5.1 m16.6 ft | 0.2 m0.8 ft |
| 10 m33 ft | 10.1 m33.2 ft | 0.5 m1.5 ft |

| 30 m98 ft | 30.3 m99.5 ft | 1.4 m4.6 ft |
Calculated from the horizontal field of view in the specifications below: width = 2 × distance × tan(FOV ÷ 2). Lens distortion and mounting angle are not included.
Who uses it, where it goes and how to install it
Written for the IPC6624SR-X33-VD2 from its own datasheet: 4 MP at up to 30 fps, 33x optical zoom (4.5–148.5 mm), 0.0005 lux color sensitivity, 200 m smart IR, UNV Large Model auto-tracking, PoE+ or 24 V AC/DC (max. 20.90 W).
Who it is for
- Long approach roads, ports and border fences — The 148.5 mm tele end identifies a face up to 317.3 m and recognizes a known person up to 634.5 m in good light, so one pole can watch a long stretch.
- Malls, car parks and commercial complexes — People flow counting and crowd density detection feed footfall data, and UNV Large Model auto-tracking follows a person or vehicle through occlusion and crossing targets.
- Perimeters and rooftops — Cross line, intrusion and enter/leave area detection classify human, non-motor vehicle and vehicle to filter false alarms; 2 alarm inputs and 1 output connect fence sensors or a siren.
- Dimly lit sites where visible light is unwanted — Color down to 0.0005 lux (F1.5, AGC on) keeps a color picture under weak street lighting, and in full darkness the 200 m IR takes over without lighting up neighbors or drivers.
Where and how to install
- Height and line of sight — Mount it high, typically 5–10 m on a pole or roof edge, with a clear view down the road or fence you want to zoom on; at full zoom a single tree or sign in the line of sight blocks the whole picture. Directly below the dome it looks almost straight down.
- Bracket for a 5.21 kg dome — The Ø227 × 390 mm dome weighs 5.21 kg and needs a proper PTZ dome wall, pole, corner or ceiling bracket. This datasheet has no accessory list or dimensional drawing, so confirm the bracket and any enclosure cutouts with us before ordering.
- Power and cable — Use one source: an 802.3at (PoE+) port, up to 30 W, or DC 24 V / AC 24 V; the camera draws up to 20.90 W, which an 802.3af port (15.4 W) cannot supply. Keep copper runs within 100 m, check that at least 18 V (24 V −25%) reaches the camera on long 24 V runs, and make the cold-pressed wire joints in a junction box.
- Lightning and earthing — Built-in surge protection is 6 kV; poles and rooftops still need external surge protectors on the network and power lines and a good earth. The housing is IP67 / IK10, with the front window excluded from IK10.
- Avoid IR reflection and heat shimmer — Keep the dome clear of walls, eaves and branches it can see at some position, or IR bounces back and whitens the night image. For long daytime zoom, avoid looking low across hot roofs or asphalt where the air shimmers; mounting higher and using heatwave reduction help.
Wide or zoomed in: what you actually see
At 4.5 mm the IPC6624SR-X33-VD2 covers about 50.5 m of width at 50 m. At 148.5 mm the view narrows to 2.68°, about 4.7 m wide at 100 m, so a single person far down a road fills much of the frame. DORI distances beyond 200 m apply in daylight or lit areas; at night the IR reaches 200 m.
| Wide · 4.5 mm | Tele · 148.5 mm | |
|---|---|---|
| Horizontal view angle | 53.61° | 2.68° |
| Width covered at 10 m | 10.1 m | 0.5 m |
| Width covered at 50 m | 50.5 m | 2.3 m |
| Width covered at 100 m | 101.0 m | 4.7 m |
| Identify a stranger's face up to | 10.6 m | 317.3 m |
| Recognize someone you know up to | 21.2 m | 634.5 m |
| See what a person is doing up to | 42.3 m | 1269.0 m |
| Detect that something is there up to | 105.8 m | 3172.5 m |
| IR night distance | 200 m | 200 m |
- Use the wide end (4.5 mm) as the home position over a car park or plaza: at 50 m it covers about 50.5 m of width.
- Save zoomed presets on distant gates and road sections: at full zoom a face is identifiable up to 317.3 m in good light.
- At night keep important presets within the 200 m IR range, or add lighting; beyond that the camera relies on existing light.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); identify/recognize/detect distances are the manufacturer's DORI figures (EN 62676-4) from the datasheet.

4MP 33x Lighthunter PTZ FAQ — IPC6624SR-X33-VD2
How well does the IPC6624SR-X33-VD2 see in very low light?
The 1/2.8-inch sensor with ColorHunter and Wise-ISP keeps color images down to 0.0005 lux (F1.5, AGC on) — starlight-level darkness — before switching to 0 lux with IR. That means license plates and clothing colors stay in color on unlit roads that other settings would render grey.
What does the auto tracking do on this model?
Auto tracking runs on the UNV Large Model: the PTZ locks a moving target and follows it hands-free. It works with smart intrusion prevention — cross-line, intrusion, enter and leave area detection with false-alarm filtering — plus people flow counting and crowd density detection for busy public sites.
What is the IR range and zoom reach at night?
Smart IR reaches 200 m with auto or manual control, and the 4.5–148.5 mm lens provides 33x optical zoom with 8x digital on top. Adaptive HLC and 120 dB WDR tame headlights and gate lighting, while digital defog and DIS stabilization keep the telephoto image steady.
Can it keep recordings locally on the camera?
Yes, edge storage supports microSD cards up to 512 GB, with NAS (NFS) available as network storage. Five simultaneous streams — main at 4 MP (2688 × 1520) 30 fps — feed the recorder, mobile clients and the local card, with bit rate control from 128 Kbps to 16 Mbps.
Will it survive extreme weather on an exposed pole?
Rated IP67 against dust and water and IK10 against impact, it operates from -40 to 70 °C — one model for tropical storms, desert heat and cold highlands. Two-way audio with G.711U, G.711A and AAC-LC lets operators broadcast warnings through a connected speaker.
Can it run automated patrol tours of my site?
Yes. Preset patrol supports 16 patrols with up to 64 presets each and stay times from 15 to 1800 seconds per position. Between tours, smart intrusion prevention and UNV Large Model tracking take over when something crosses a line or enters a protected zone.
Will the IPC6624SR-X33-VD2 work with a Hikvision, Dahua or other non-Uniview NVR or VMS?
Usually yes for live view, recording and PTZ control: it supports ONVIF Profile S, G, T and M, plus RTSP, SDK and API. Auto-tracking runs inside the camera, but intrusion rules, people counting and tracking settings are configured in its web interface or on Uniview NVRs and clients (EZStation, UNV-Link, UNV-Link Pro), and smart event alarms may be limited on other brands. Tell us your NVR or VMS model and we will confirm before you order.
How many IPC6624SR-X33-VD2 cameras can one PoE switch power?
Divide the switch's total PoE budget by about 21 W (the camera's maximum is 20.90 W) and use only 802.3at (PoE+) ports, which give up to 30 W each. For example, a switch with a 120 W budget runs 5 of these cameras at full load, with some margin left. The camera's port is 10/100 Mbps and its stream at most 16 Mbps, so Fast Ethernet PoE+ ports are enough; use a gigabit uplink to the NVR when many cameras share it.
IPC6624SR-X33-VD2 or IPC6624SR-X25-VD2: which zoom do I need?
It depends on the farthest point you must identify. By the two datasheets, the X33 (4.5–148.5 mm) identifies a face up to 317.3 m at full zoom, while the X25 (4.8–120 mm) reaches 240.8 m; both have 200 m IR, the same auto-tracking and the same 30 fps limit. If your key targets are within about 240 m, the X25 is enough; for longer roads, ports or fence lines choose the X33.
What is the difference between the IPC6624SR-X33-VD2 and the IPC6624SR-X33-VD2A?
Same 33x zoom range, 200 m IR and DORI figures, but by the two datasheets the VD2 has the more capable feature set: UNV Large Model auto-tracking, five video streams, color down to 0.0005 lux, IP67 and max. 20.90 W. The VD2A uses a 1/2.7" sensor with color down to 0.002 lux, three streams (main stream up to 60 fps, sub stream 30 fps), 16x digital zoom, standard auto-tracking with target filtering and no multi-target detection, IP66, and 23.9 W. Choose the VD2 for low light and smart tracking; the VD2A if 60 fps on the main stream matters more.
Can the IPC6624SR-X33-VD2 read license plates?
It can show a plate on a zoomed preset aimed at one lane where vehicles slow down, mainly in daylight; at 148.5 mm the view is about 2.3 m wide at 50 m. No license plate recognition (LPR) is listed, and at night reflective plates often flare under IR even with HLC. For reliable plate capture at a barrier, add a dedicated plate camera and keep this PTZ for overview and tracking.
Why does the IPC6624SR-X33-VD2 picture wobble at full zoom on hot afternoons?
That is heat shimmer: hot air rising from roads and roofs bends the light, and a 2.68° tele view magnifies it. Turn on heatwave reduction, mount the camera higher so it looks down through less hot air, and for the hottest hours save a preset slightly zoomed out. If the whole picture shakes rather than ripples, the pole is moving: this model uses DIS digital stabilization, so a stiffer pole or a wall mount helps most.
