SKU CH-FMYK-JAKGM

Four 8MP PoE cameras with motorised 2.8-12mm varifocal lenses deliver 4K video, human and vehicle detection, colour night vision and up to 512GB on-board storage

  • Bundled Camera Number4
  • 4K 8MP resolution reveals fine details at 3840×2160
  • Motorised 2.8–12mm varifocal lens gives 4× optical zoom from 68 m to 200 m detection
  • Human and vehicle detection with 99 % accuracy triggers sound and light alarms
  • Smart dual-light mode switches between full-colour and IR night vision automatically
  • Single PoE cable delivers power and video with H.265+ compression up to 512 GB storage

Four-camera 4K PoE surveillance kit

This system bundles four 8-megapixel dome cameras that stream 3840 by 2160 video at up to 15 frames per second. Each camera uses a single Ethernet cable for both power and data, simplifying installation for home or small-business owners who want high-resolution coverage without separate power runs. Built-in microphones capture audio with environment noise filtering.

PoE bandwidth and storage limits

One cable carries video, audio and power, so the network switch must supply enough PoE budget for all four cameras simultaneously. On-board recording relies on a micro-SD slot that accepts cards up to 512 gigabytes; H.265+ compression keeps bit-rates between 32 kilobits and 16 megabits per second, but continuous 4K recording will fill the card faster than lower-resolution streams.

Motorised zoom and night-vision range

The 2.8-to-12-millimetre motorised varifocal lens lets you adjust the field of view remotely, providing detection ranges from 6.8 to 200 metres depending on zoom level. Dual-light night vision switches between infrared and full-colour modes, while human and vehicle detection reduces false alerts. Buyers who need more than four cameras or longer retention than a single 512-gigabyte card provides should plan for additional storage.

Questions about this item

How do I decide between the motorised varifocal and a fixed-lens option?

The 2.8-12mm motorised varifocal lets you adjust the field of view remotely from wide-angle to telephoto, so one camera can cover both a broad area and distant detail without swapping hardware.

What does the 8 MP / 3840×2160 resolution actually deliver on my NVR?

At 50 Hz the main stream records 12.5 fps at 3840×2160, or 20 fps at 2688×1520 and 1920×1080; at 60 Hz it reaches 15 fps at 3840×2160 and 20 fps at the lower resolutions.

What does the PoE interface cap in real use?

A single Ethernet cable carries both power and video up to 16 Mbps bitrate with H.265+ compression, removing the need for a separate 12 V supply.
