Description

PTZ Dome IP Camera  with 3K 5MP resolution. It has a motorised 2.8-12mm varifocal lens, full PTZ movement and DarkVu night-vision technology (F1.5). It includes two-way audio, a full suite of Smart Event AI functions (face detection, intrusion, abandoned objects) and a MicroSD slot for cards up to 512GB. Extremely tough, with IP66 certification, IK10 anti-vandal rating and TVS 4000V lightning protection. PoE or 12V powered.

IP surveillance camera (2026 updated version) of the Dome type, combining a discreet shape with the power of motorised PTZ (Pan-Tilt-Zoom) systems. Its 3K Super HD resolution (3072×1728 pixels) gives extremely detailed, sharp images, clearly better than standard Full HD. It is the right choice for anyone who wants to watch over large commercial spaces, yards or awkward entrances without installing several fixed cameras.

Motorised Movement and True 4X Optical Zoom

Unlike fixed models, this one can turn horizontally (Pan) and tilt vertically (Tilt) remotely from a smartphone, a PC or an NVR, leaving no blind spot. Its real strength is the 4X Optical Zoom: not simple digital magnification (which would break the image up), but a mechanical movement of the lenses that brings distant details closer (faces, number plates) while keeping the resolution at its best.

Simpler Installation with PoE

No tangle of cables, no power supply next to the camera. This model also supports PoE (Power over Ethernet): a single LAN cable carries both the high-speed video data and the power for the camera. A clean, stable and safe solution that halves installation time and cost.

Armoured against Weather and Vandals

Built to stand up to the harshest environmental and security conditions, the housing carries two ratings: an IP66 protection rating (fully resistant to driving rain, dust and extreme temperatures, which makes it ideal for outdoor installation) and IK10 impact resistance (the protective dome is built to take tampering attempts or violent impacts, shielding the optics inside from vandalism)

Varifocal Optics and Advanced DarkVu Night Vision

With a varifocal lens from 2.8 to 12 mm, the camera offers a wide horizontal field of view (99.4° down to 32.8°), so it handles both wide shots and tight zooms on distant details. Horizontal rotation (PAN 0° to 355°) and vertical tilt (TILT 0° to 90°) leave no blind spots. After dark, DarkVu technology comes in alongside infrared vision up to 20 metres: the generous Max F1.5 aperture gathers the remaining light for remarkably sharp footage even with as little as 0.005 lux of illumination.

The camera can be used together with an NVR (Annke, or any ONVIF-compatible unit able to work at 3K resolution), or on its own with a microSD card inside, using the Annke Vision app to watch from a smartphone.


Proactive Security with Smart Event and Two-Way Audio

Annke camera with SMART functions

The camera does not just record: it analyses what it sees, with a full set of built-in intelligent functions:

  • Detection and analysis: includes Face detection, Line crossing and Intrusion detection.
  • Area monitoring: watches entries into and exits from predefined areas (Region entrance/exiting).
  • Object protection: instantly spots Unattended baggage or the unauthorised removal of items (Object removal).
  • With two-way audio (Two way audio), you can listen to what is happening on site or speak straight through the camera using the ANNKE Vision app. If something is wrong, the audible alarm and push notifications alert you in real time.

PTZ and ZOOM Functions

The picture above shows how flexible the camera is in use. Thanks to its precision internal motors, it offers full Pan/Tilt movement covering 355° horizontally and 90° vertically. That lets you patrol whole areas with a single unit, pointing the lens exactly where you need it from the smartphone app, a PC or an NVR. The real difference is the true 4X Optical Zoom (2.8-12 mm focal length):

  • No pixellation: unlike the digital zoom of cheaper models, which merely enlarges the pixels and ruins the image, optical zoom moves the lenses mechanically.
  • Sharp forensic detail: going from the wide view (1x) to maximum magnification (4x), the 3K 5MP resolution stays crystal clear, so you can read distant number plates or make out the features of a face precisely.

Extreme protection with IK10 anti-vandal rating


With a 3K OmniVision sensor, this PTZ camera delivers remarkable 3K super HD video quality. 4 advanced image enhancement technologies, 3D DNR, HLC, EIS and 120 dB true WDR, take clarity to a new level. Colour night vision footage works even with ambient light down to 0.005 lux, capturing images in colour up to 20 m away.


Unmatched 3K Super HD and colour night vision


The rugged dome security camera is built to an IK10 anti-vandal rating, which lets it withstand violent, destructive impacts of up to 20 joules. Made of metal and ABS materials (supplied by SABIC, the largest listed company in the Middle East and Saudi Arabia), it can look after itself while it protects your property. Watch the video on the right to see how the IK10 rating performs.

Colour night vision footage works even with ambient light down to 0.005 lux, capturing every image in rich colour whatever the night is like, up to 20 m away.
