Need the PDF datasheet? Get it on WhatsApp →The IPC6424SR-X25-VF-B is a 4 MP network PTZ dome camera built around a 1/2.8" CMOS sensor and a 25× optical zoom lens (4.8-120 mm, F1.5-F3.8, 16× digital zoom) for long-range detail on a single moving lens. LightHunter low-light processing holds color down to 0.003 Lux (F1.5, AGC on), backed by 120 dB WDR and a Smart IR illuminator reaching 100 m for full day/night coverage. Onboard analytics cover auto tracking with human/vehicle/non-motor classification, smart intrusion prevention (cross line, intrusion, enter/leave area with false-alarm filtering) and people-flow/crowd-density counting, all inside an IP67, IK10 vandal-resistant housing rated -40 °C to 70 °C.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
- No built-in microphone or speaker — Built-in Mic and Built-in Speaker are both listed N/A. Two-way audio is supported, but only via an external mic/speaker wired to the 1-in/1-out audio I/O.
- No Wi-Fi — the datasheet lists WIFI as N/A. Network connection is wired only, via a single 10 M/100 M RJ45 port.
- Network interface is 10 M/100 M Fast Ethernet, not Gigabit — confirm bandwidth budget before running multiple high-bitrate streams over a shared switch uplink.
- This is a classic single-sensor PTZ, not a panoramic-linkage unit — if you need simultaneous 360° overview plus zoom detail from one pole, choose a panoramic-linkage PTZ instead.

Two Strengths in One Dome: Long-Range Zoom + Smart Analytics
What actually makes this a perimeter camera, not just a zoom camera.
25× optical zoom (4.8-120 mm, F1.5-F3.8) plus 16× digital zoom pulls in distant detail without losing the wide view when zoomed back out.
Auto tracking, smart intrusion prevention and people counting run on the camera itself, turning raw video into perimeter alerts instead of footage someone has to watch live.
How far can it see? (DORI)
DORI (EN 62676-4) is the industry standard for what a camera can do at distance. Values shown are at full 25× telephoto (4.8-120 mm lens, 120 mm end); the wide end of the zoom gives shorter distances with a wider field of view.
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 | 52.2° wide | 2.7° tele |
|---|---|---|
| 5 m16 ft | 4.9 m16.1 ft | 0.2 m0.8 ft |
| 10 m33 ft | 9.8 m32.1 ft | 0.5 m1.6 ft |
| 15 m49 ft | 14.7 m48.2 ft | 0.7 m2.4 ft |
| 20 m66 ft | 19.6 m64.3 ft | 1.0 m3.1 ft |
| 30 m98 ft | 29.4 m96.4 ft | 1.4 m4.7 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 IPC6424SR-X25-VF-B from its own datasheet: 4 MP (2688×1520), 25x optical zoom (4.8–120 mm), auto-tracking of people and vehicles, 100 m Smart IR, IP67 and IK10, PoE+ (max. 21 W).
Who it is for
- Factories, yards and perimeters — Smart intrusion prevention raises the alarm and auto-tracking then follows the person or vehicle; at 120 mm a person is identifiable up to 247.5 m in good light.
- Stations, plazas and plant gates — People counting with crowd-density monitoring, plus audio I/O 1/1 to an external speaker and alarm I/O 2/1 to trigger barriers or strobes.
- Roads, intersections and expressways — 4 MP detail at long zoom, target classification for mixed traffic, and heatwave reduction that limits the shimmer of hot asphalt in long-range shots.
- Exposed or vandal-prone poles — IP67 and IK10 housing, -40 °C to 70 °C working range and 6 kV surge protection, for sites that are hard to reach for service.
Where and how to install
- Height and view — Mount high, typically 4–6 m on a pole or building corner, with nothing close in front of the dome, so it looks over vehicles, fences and people. The -VF-B datasheet does not list the pan and tilt ranges; ask us if the site needs the camera to look above the horizon.
- A rigid mount for 25x zoom — The camera weighs 3.05 kg and at 120 mm the view is only 2.74° wide, so the slightest sway shows as shaking. Use a short, stiff wall bracket (TR-WE45-IN) or a pole bracket (TR-UP08-A-IN or the aluminium TR-UP08-B-IN) on a thick, guyed pole; the long arm TR-WE45-A-IN shakes more at full zoom.
- Other mounts and the junction box — Corner: TR-UC08-A-IN or aluminium TR-UC08-B-IN. Ceiling: TR-CE45-IN, TR-UF45-A-IN, or pendant poles TR-SE45-IN (200) and TR-SE45-A-IN (500). Gooseneck: TR-WE45-B-IN. Put the cable joints in the TR-JB12-IN dome junction box.
- Power and cable — Use a PoE+ (IEEE 802.3at) port or a 12 V DC 3 A supply; maximum draw is 21 W, more than an 802.3af port (15.4 W) can give. Keep copper runs within 100 m; for longer distances use fibre to a switch near the pole.
- Lightning and earthing — Built-in surge protection is 6 kV. On a metal pole or a rooftop, add a surge protector on the network cable at both ends and bond the pole to earth; tall PTZ poles are the most common lightning victims on a site.
- Keep the IR path clear — The 850 nm IR reflects off eaves, walls, branches or dirt on the dome and washes out the night image. Keep the dome clear of the wall, trim trees in the IR path and check every preset at night.
Wide or zoomed in: what you actually see
At 4.8 mm the IPC6424SR-X25-VF-B gives an overview about 9.8 m wide at 10 m. At 120 mm the view is about 2.4 m wide at 50 m and 4.8 m at 100 m, which puts roughly 1124 pixels on each metre of the scene at 50 m (2688 ÷ 2.4): one person or one vehicle fills the frame. DORI distances beyond 100 m need daylight or a lit scene, because the IR reaches 100 m.
| Wide · 4.8 mm | Tele · 120 mm | |
|---|---|---|
| Horizontal view angle | 52.20° | 2.74° |
| Width covered at 10 m | 9.8 m | 0.5 m |
| Width covered at 50 m | 49.0 m | 2.4 m |
| Width covered at 100 m | 98.0 m | 4.8 m |
| Identify a stranger's face up to | 11.9 m | 247.5 m |
| Recognize someone you know up to | 23.9 m | 495.0 m |
| See what a person is doing up to | 47.7 m | 990.0 m |
| Detect that something is there up to | 119.3 m | 2475.0 m |
| IR night distance | 100 m | 100 m |
- Set the home position near the wide end for situational awareness: at 50 m the 4.8 mm view still covers 49.0 m.
- Save zoomed presets on gates, fence corners and roads: at 120 mm a person is identifiable up to 247.5 m in daylight.
- At night, keep presets that matter within the 100 m IR range or light those areas.
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.
