IP dome security camera UBIQUITI AI Multi Sensor 4 — 3840×2160, 360° FOV, 2.33× optical zoom, ceiling mount, wired (white/black)

The UBIQUITI AI Multi Sensor 4 is a wired IP dome security camera designed for ceiling installation both indoors and outdoors. It captures up to 3840×2160 resolution (32 MP effective) across a 360° field of view using four independently adjustable lenses and dual horizontal viewing angles (108.8° and 42.8°). The camera uses CMOS sensors with a 1/2.8" optical format, offers 2.33× optical zoom with a focal length range of 3.18–7.42 mm, and is available in white or black housing. The device supports Power over Ethernet and is built to withstand outdoor conditions with IP66 and IK10 ratings.

Advantages

The Multi Sensor 4 combines wide-area coverage and optical zoom to allow both panoramic surveillance and detailed close-ups without moving parts. A high effective sensor resolution and CMOS sensor technology provide detailed images at up to 3840×2160, while four adjustable lenses let you tailor coverage to a specific layout. Weatherproof and tamper-resistant construction enables reliable ceiling-mounted operation in exposed locations, and wired connectivity with PoE simplifies power and data delivery over a single cable.

Suitable for

• Large indoor public spaces such as lobbies, retail floors, and stations
• Perimeter monitoring and access control at building entrances
• Parking areas, covered exterior walkways, and sheltered outdoor zones
• Multi-angle surveillance where a single ceiling-mounted dome should replace multiple fixed cameras

When it may not be suitable

This ceiling-mount dome is a wired PoE device intended for fixed installations; it is not designed as a battery-powered or wireless camera for temporary or rapidly relocatable deployments. Environments that require extreme long-range zoom beyond 2.33× optical zoom or highly specialized imaging hardware (thermal, ultrawide beyond the supplied FOV, or interchangeable lenses) may need a different camera model.

Key specifications

• Mounting type: Ceiling dome
• Ingress and impact protection: IP66 and IK10
• Night vision: IR illumination up to approximately 20 m
• Connectivity: Wired Ethernet (PoE support)
• Form factor and colours: Dome; available in white and black
• Weight: 2.4 kg

How to use

Install the camera on a suitable ceiling surface using the included ceiling-mount hardware and follow safety and local electrical regulations. Connect the camera to a PoE-capable network switch or injector to provide power and data over a single Ethernet cable. Use the vendor’s management software or interface to configure camera orientation, lens adjustments, resolution, and motion/AI settings. For outdoor ceiling locations, ensure the mounting location provides shelter from direct water jets and that cable entries are sealed according to the installation instructions.

What to consider before purchase

• Availability of PoE++ or compatible PoE power on-site
• Ceiling structure and load capacity to support a 2.4 kg dome camera
• Required field of view and whether 2.33× optical zoom meets identification needs
• Network infrastructure and bandwidth for 4K (3840×2160) streams
• Environmental conditions and whether IP66 / IK10 ratings match exposure

Recommendations

Position the dome centrally to the area you need to monitor to take full advantage of the 360° coverage and set individual lens angles to eliminate blind spots. Configure resolution and frame rate according to available network bandwidth, and enable onboard AI features where supported to reduce false alerts and prioritize recording of relevant events.
