4MP 25× LightHunter PTZ Dome · Smart IR 100 m

IPC6424SR-X25-VF

Name: IPC6424SR-X25-VF
Brand: Uniview

A 4MP PTZ dome camera with 25× optical zoom (4.8–120 mm) that locks onto and tracks people and vehicles automatically — LightHunter low-light imaging and Smart IR to 100 m keep it working after dark, in an IP67/IK10 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.

City road checkpoints25× optical zoom (4.8–120 mm) reaches deep into an intersection while auto tracking classifies human, non-motor vehicle and vehicle targets — built for reading plate and lane detail from a checkpoint pole.

Transportation hubs & interchangesSmart intrusion prevention (cross line, intrusion, enter/leave area) with false-alarm filtering by classification covers ramps and platform edges, while people counting reports flow and crowd density across a busy hub.

Mixed traffic at intersectionsTarget-classification filtering separates cars, non-motor vehicles and pedestrians so alarms stay meaningful in dense mixed traffic; the 0.1–200°/s tilt and 0.1–288°/s pan give the operator fast manual pursuit when needed.

Night patrol on expressways & ring roadsLightHunter low-light processing plus Smart IR up to 100 m keep the scene visible after dark, and heatwave reduction stops summer road heat from smearing long-zoom footage on straight expressway stretches.

Crowd flow at transit stationsPeople counting reports flow statistics and crowd-density monitoring suited to different statistical scenarios — useful for gate queues and platform crowding without a dedicated people-counting camera.

Harsh outdoor pole mountsIP67 sealing, IK10 vandal resistance, -40 °C to 70 °C operation and 6 kV surge protection let it sit on an exposed road-side or overpass pole through heat, cold and storms.

Not the right pick if you need…

No built-in mic or speaker and no Wi-Fi (all N/A per datasheet) — audio and wireless connectivity need an external device or a different model.
No on-device face-recognition library — auto tracking classifies human / non-motor / vehicle targets but does not match faces against a watch list; a panoramic-linkage model is the pick for face-DB requirements.
Network port is 10 M/100 M Base-TX, not Gigabit — plan bandwidth accordingly if you run high-bitrate triple streams to a distant NVR.
Illuminator is Smart IR only (850 nm, up to 100 m) — there is no warm-light option on this model; for full-color night capture at range, a dual-light PTZ is the better fit.

Worried about counterfeits? Order under your own company name.

For corporate buyers: we support submitting the purchase order to Uniview under your company's real name — your company appears on the official order, so the origin of the goods can be verified directly with the manufacturer. Just provide your company name and pay by corporate bank transfer. Models carrying the anti-counterfeit label can also be self-verified on Uniview's official Anti-Counterfeiting Query page — enter the unit's SN plus the scratch-off code.
