Knight Watch 40 Bullet Camera

The Knight Watch 40 camera utilises leading-edge sensor technology, with a Super low-light CMOS sensor for high-quality images in daytime or night-time settings. PoE power means simple plug and play experience, with low power consumption (12W, IR on). A motorised Zoom lens with Auto Focus system ensures crisp, clear images all the time. A tough, stylish housing completes the high-quality offering.

Adaptive IR Illumination

Integral IR LEDs provide up to 60m of Adaptive IR range, ensuring any night-time activity is captured in full HD with stunning image quality. The Knight Watch 40 automatically adjusts the IR intensity in proportion to zoom and scene content. The IR LEDs are fully isolated from the camera lens, meaning no glare or haze, only crystal-clear images all night long.

Motorised Zoom

A fully motorised 3.6mm ~ 11mm Smart Auto Focus lens guarantees sharp images in both day and night-time, whilst making installation setup quick and easy.

Aluminium Body

A tough, solid cast aluminium casing results in the camera being well-protected against the elements and local environment, to IP66 standard. A rugged aluminium housing secures the camera whilst keeping the premises secure.

SD Card Edge Recording

Built-in SD Card recording up to 256GB allows network edge-recording, making sure nothing is missed, even in the event of a network data outage. ONVIF Profile G compliance means the camera can work with a compatible VMS platform or NVR, to automatically interrogate and recover recorded footage, as soon as the network connection is restored.

ONVIF Compliant

ONVIF Profile S, G and T compliance offers compatibility with countless VMS platforms and NVRs. A H.265 streaming option means high-quality images at lower network bandwidth and hard-disk storage.

Additional Features

Motion Detection, Intelligent Video Analytics, Smart Encoding and Region of Interest allow users to tailor cameras to suit each individual scene, optimising recording time for only events or information that really matters to you.

Simple Installation

3D positioning arm allows users to find that perfect spot to view exactly what’s required. An adjustable Sunshield ensures unwanted glare is kept out in almost any installation positions.

Microphone and Speaker

A built in microphone and loudspeaker allow users to operate two way audio to sites at a click of a button.
