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.
Industrial park & factory perimeterSmart intrusion prevention covers cross-line, intrusion, enter-area and leave-area detection with false-alarm filtering and human / non-motor vehicle / vehicle classification — built to watch a fence line instead of flooding the guard room with false alerts.
Factory gate & yard entranceAuto tracking locks onto a person, non-motor vehicle or vehicle crossing the gate and follows it automatically, while the 25× optical zoom (4.8-120 mm) pulls in close enough to read faces or plates from the guard post without repositioning the camera.
Low-light yards & storage areasLightHunter processing holds a usable color image down to 0.003 Lux (F1.5, AGC on); once it is fully dark, Smart IR reaches 100 m so a wide unlit yard is not left blind between dusk and sunrise.
Harsh outdoor pole mountsIP67 sealing, IK10 vandal resistance and a -40 °C to 70 °C operating range let this dome sit on an exposed perimeter pole through heat, dust storms and freezing winters without a protective enclosure.
People-flow at plant gatesPeople counting supports flow statistics and crowd-density monitoring across multiple zones, useful for shift-change headcounts at a factory gate or occupancy checks in a logistics yard.
Simplified perimeter cablingPoE+ (IEEE 802.3at) or DC 12 V power plus a 2/1 alarm I/O let a pole run on a single cable and still trigger gate barriers or strobe lights when an intrusion event fires — no separate power drop needed at every post.
Not the right pick if you need…
- 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.
LONG-RANGE ZOOM
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.
undefined
SMART ANALYTICS
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.

4MP 25x PTZ Camera FAQ — IPC6424SR-X25-VF-B
How far can the IPC6424SR-X25-VF-B identify a person?
With the 4.8–120 mm lens (25x optical, 16x digital, F1.5–F3.8), DORI figures run: detect up to 2475 m, observe up to 990 m, recognize up to 495 m and identify up to 247.5 m at full zoom. One unit can watch a very long fence line or approach road.
What is its night vision like?
Per the listing it carries 100 m Smart IR for full darkness, and LightHunter color imaging holds to 0.003 lux (F1.5, AGC on) before IR is needed. Smart IR exposure control avoids overexposing close subjects; 120 dB WDR, digital defog and heatwave reduction keep the image usable.
Does it track people and vehicles automatically?
Yes. Auto tracking filters for humans, non-motor vehicles and vehicles, following the target as it moves through the scene. Smart intrusion prevention provides cross-line, intrusion, enter-area and leave-area detection with false-alarm filtering, and people flow counting plus crowd density monitoring are supported.
What streams does it output to the NVR?
Triple streams: 4 MP (2688×1520) at up to 30 fps on the main stream, 1080p on the sub stream and D1 on the third. Bit rate is adjustable from 128 Kbps to 16 Mbps across Ultra 265, H.265, H.264 and MJPEG, so you can balance image quality against disk and bandwidth.
Is the housing tough enough for exposed sites?
Per the listing the housing is rated IP67 against dust and water immersion and IK10 against impact — the common spec asked for on roadside poles, depots and coastal sites. It also has alarm input/output contacts, tampering alarm and two-way audio for on-site response.
