The IPC6624SR-X25-VH2 is a 4MP intelligent network PTZ camera with a 25× optical / 8× digital zoom lens (4.8-120 mm, F1.65-F3.8) on a 1/2.8" CMOS sensor, delivering 2688×1520 video up to 60fps. UNV Large-Model auto tracking, smart intrusion prevention with cross-line / enter-area / leave-area detection and person / vehicle / non-motor classification, people counting with crowd density monitoring, and Wise-ISP low-light processing (ColorHunter) with EIS gyroscopic stabilization handle day-and-night surveillance on a single pole. A 120 dB true WDR sensor, 200 m smart IR illumination, adaptive highlight compensation, heat-haze reduction and digital defog keep the image usable in glare, heat shimmer and fog, while an IP67 / IK10 housing rated -40 °C to 70 °C and PoE (IEEE 802.3at) / DC 24 V / AC 24 V power options suit demanding outdoor mounts.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Perimeter fences & yardsSmart intrusion prevention covers cross-line, enter-area, leave-area and intrusion detection with false-alarm filtering and classification of people, vehicles and non-motor traffic — so alerts are about real targets, not blowing leaves.
Wide-open areas with auto-trackingUNV Large-Model auto tracking accurately identifies and continuously tracks motor vehicles, non-motor vehicles and pedestrians — even through occlusion, multi-target crossing or high-speed motion — with real-time adaptive bounding boxes.
Road entrances & intersectionsAdaptive highlight compensation automatically adjusts image brightness at night when moving vehicles are detected on the road, while 25× optical zoom (4.8-120 mm) reads plates and faces at distance.
Parks, campuses & public spacesBuilt-in people-flow counting and crowd-density monitoring apply to various scenarios, giving operators an early read on crowding before it becomes a safety issue.
Night operation, long rangeColorHunter with Wise-ISP keeps low-light images usable; when it gets fully dark, 200 m smart IR takes over automatically, and the DORI Detect range reaches up to 2407.5 m at full 25× zoom.
Harsh outdoor mountsIP67 sealing, IK10 vandal resistance except the front window, -40 °C to 70 °C operation and 6 kV surge protection are built for the pole nobody wants to climb twice — with PoE (802.3at), DC 24 V or AC 24 V power options.
Not the right pick if you need…
- No panoramic/wide fixed channel — this is a single-lens PTZ. At full 25× zoom the field of view narrows to about 3° horizontal; if you need simultaneous full-scene coverage plus zoom detail, choose a panoramic-linkage model instead.
- No warm/white light — illumination is IR only (200 m). For full-color night evidence of faces and plates, plan a separate white-light source.
- 5.18 kg on a Ø227×390 mm housing — needs a proper ceiling/pole/wall bracket from the accessory list, not a light camera arm.
- PTZ motors add load on top of the base draw — max. power consumption is 20.7 W, so if powering over PoE (802.3at), check the switch port's power budget before deploying multiple units.

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.

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-X25-VH2 from its own datasheet: 4 MP at up to 60 fps, 25x optical zoom (4.8–120 mm), gyroscope EIS stabilization, 200 m smart IR, UNV Large Model auto-tracking, PoE+ or 24 V AC/DC (max. 20.7 W).
Who it is for
- Roads, junctions and fast vehicle traffic — Main and sub streams run up to 60 fps, so moving vehicles show less blur between frames, and adaptive highlight compensation (HLC) lowers headlight glare at night.
- Tall poles, bridges, ports and windy sites — EIS with a gyroscope measures the camera's own movement and steadies the image, which matters most at the 120 mm tele end where a small sway moves the whole picture.
- Perimeters and open yards — Cross line, intrusion and enter/leave area rules with human / non-motor vehicle / vehicle classification start the alarm, and UNV Large Model auto-tracking follows the target with the 25x zoom.
- Parks, campuses and public spaces — People flow counting and crowd density detection show when an area gets crowded, and object left behind / object removed detection flags unattended items.
Where and how to install
- Height and position — Mount it high, typically 5–10 m on a pole or building corner, with a clear line of sight along the road or yard. Use a rigid, well-anchored pole: EIS reduces shake, but a stiff pole is still the best stabilizer at full zoom.
- Brackets for a 5.18 kg dome — Wall: TR-WE45-IN, or the long TR-WE45-A-IN to clear eaves; gooseneck: TR-WE45-B-IN; pole: TR-UP08-A-IN or aluminium TR-UP08-B-IN; corner: TR-UC08-A-IN or TR-UC08-B-IN; ceiling: TR-SE45-IN / TR-SE45-A-IN. Use the TR-JB12-IN junction box to house the cable joints.
- 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 20.7 W. Keep copper runs within 100 m, and on long 24 V runs check that at least 18 V (24 V −25%) reaches the camera. The power leads are wires with cold-pressed terminals: protect the joint in the junction box.
- Lightning and earthing — Built-in surge protection is 6 kV; on a metal pole add external surge protectors on the network and power lines and earth the pole and bracket. The housing is IP67 / IK10, with the front window excluded from IK10.
- Avoid IR reflection — Keep the dome clear of walls, eaves and branches that come into view at some pan or tilt position; reflected IR turns the night picture white. Check every preset after dark, and clean the window when spider webs or dust build up.
Wide or zoomed in: what you actually see
At 4.8 mm the IPC6624SR-X25-VH2 covers about 50.8 m of width at 50 m. At 120 mm the view narrows to 3.00°, about 2.6 m wide at 50 m and 5.2 m at 100 m, so one lane or one person fills the frame. DORI distances beyond 200 m apply in daylight or lit areas; at night the IR reaches 200 m.
| Wide · 4.8 mm | Tele · 120 mm | |
|---|---|---|
| Horizontal view angle | 53.90° | 3.00° |
| Width covered at 10 m | 10.2 m | 0.5 m |
| Width covered at 50 m | 50.8 m | 2.6 m |
| Width covered at 100 m | 101.7 m | 5.2 m |
| Identify a stranger's face up to | 12.0 m | 240.8 m |
| Recognize someone you know up to | 24.0 m | 481.5 m |
| See what a person is doing up to | 48.0 m | 963.0 m |
| Detect that something is there up to | 119.9 m | 2407.5 m |
| IR night distance | 200 m | 200 m |
- Use the wide end (4.8 mm) as the home position over a junction or yard: at 50 m it covers about 50.8 m of width.
- Save zoomed presets on gates and lanes: at full zoom a face is identifiable up to 240.8 m in good light.
- Keep night presets within the 200 m IR range; there is no white or warm light on this model, so color at night needs site lighting.
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 25x PoE PTZ FAQ — IPC6624SR-X25-VH2
How do I power and connect the IPC6624SR-X25-VH2?
The camera supports PoE, so a single network cable from a PoE switch delivers power and carries video back — one pull to the pole top instead of separate mains and data runs. Plan one PoE port per camera and check the switch's total power budget for PTZ loads.
What resolution and frame rate does the main stream deliver?
Up to 4 MP (2688 × 1520) at 60 fps, with 25 fps as the default, across five simultaneous streams — recommended combinations include 2688 × 1520@60 + 1080p@60 + D1 sub-streams. Bit rate spans 128 Kbps to 16 Mbps with Ultra 265, H.265, H.264 and MJPEG compression.
Does it track moving people and vehicles by itself?
Yes, UNV auto tracking lets the PTZ lock onto a moving target and follow it without operator input. With 200 m IR it keeps tracking after dark, and preset patrols — 16 patrols of up to 64 presets with 15 to 1800 second stays — cover the site whenever nothing is being tracked.
Which NVRs and platforms can pull its video?
It exposes ONVIF Profile S, G, T and M plus RTSP and RTMP, so third-party NVRs and VMS platforms integrate directly, and SDK/API cover custom projects. Uniview EZStation, UNV-Link and UNV-Link Pro handle live view and playback, with up to 32 users on three permission levels.
How far does the night vision reach?
IR illumination reaches 200 m. Together with the 4.8–120 mm 25x lens, DORI distances run to 2407.5 m for detection and 240.8 m for identification at full telephoto, so the camera still resolves useful detail far beyond the lit area around the pole at night.
Is it built for harsh outdoor conditions?
The housing is rated IP67 against dust and water and IK10 against impact — suited to exposed poles on streets, borders and industrial yards. Edge storage on microSD up to 512 GB plus NAS (NFS) keeps recording through network trouble, and 120 dB WDR handles harsh backlight.
Should I record the IPC6624SR-X25-VH2 at 60 fps, and how much storage does it need?
Use 60 fps only where it helps, such as fast road traffic; the default is 4 MP (2560×1440) at 25 fps, which suits most sites. The bit rate tops out at 16 Mbps either way, about 172.8 GB per day or 5.2 TB per camera for 30 days of continuous recording; at 4 Mbps it is about 43.2 GB per day. At the same bit rate, 60 fps spreads the data over more frames, so set a higher bit rate when you raise the frame rate.
What is the difference between the IPC6624SR-X25-VH2 and the IPC6624SR-X25-VD2?
Lens, 200 m IR, auto-tracking, power and housing are the same. By the two datasheets, the VH2 runs up to 60 fps on all streams, uses EIS with a gyroscope and adds front-end blocklist/allowlist comparison, while the VD2 is limited to 30 fps, uses DIS (digital) stabilization and also lists AAC-LC audio. Pick the VH2 for fast traffic or tall, windy poles; the VD2 covers standard 25/30 fps recording.
Can one IPC6624SR-X25-VH2 cover several gates with presets and patrols?
Yes, one after another: it stores 1024 presets and 16 patrols of up to 64 presets each, with a stay time of 15 s to 1800 s per preset, and a home position it returns to. Preset image freeze keeps the recording from showing the blur while it moves between presets. It still sees only one place at a time, so while it looks at gate A, gate B is not recorded; keep a fixed camera on any gate that must be covered every second.
Can the IPC6624SR-X25-VH2 read license plates or match faces against a blocklist?
Not as a dedicated LPR or face-recognition camera. The datasheet lists best-snapshot selection, face detection masked areas and front-end blocklist/allowlist comparison, but no database size or plate recognition; at 120 mm a zoomed preset is about 2.6 m wide at 50 m, enough to see a plate on a slow lane in daylight. If matching is a requirement, tell us the scene and we will confirm with the manufacturer before you order.
Can I connect a speaker or siren to the IPC6624SR-X25-VH2?
Yes, externally; no built-in speaker is listed. The 1 audio output (600 Ω line level) feeds an amplified speaker for two-way talk, the 1 audio input takes a microphone, and the 1 alarm output can switch a siren or strobe when a cross line or intrusion rule fires; there are also 2 alarm inputs for sensors. If you prefer a built-in speaker with visible-light deterrence, the dual-light IPC6624SFW-X33-C-VH2 has one.
