Professional Features That Matter

8MP 4K Ultra HD Resolution

With a maximum resolution of 3840 × 2160, the camera captures four times the pixel detail of standard 1080p video. Higher resolution can provide more useful detail when reviewing people, clothing, packages, vehicles, entrances, and other important activity.

Wide 107° Viewing Angle

The fixed 2.8mm lens provides an approximately 107-degree horizontal field of view, making the camera well suited for monitoring broader spaces such as entrances, storefronts, driveways, warehouse aisles, offices, parking areas, and walkways.

Smart IR Night Vision up to Approximately 100 Feet

Integrated 850nm Smart IR illumination provides nighttime surveillance up to approximately 98.4 feet, marketed as up to 100 feet. The camera automatically changes from daytime color video to infrared black-and-white video as lighting conditions change.

Built-In Microphone

The integrated microphone captures one-way audio together with video. Recorded sound can add useful context to surveillance footage by documenting conversations, alarms, impacts, deliveries, and other activity near the camera when audio recording is legally permitted.

True 120dB Wide Dynamic Range

True 120dB WDR helps balance very bright and dark areas within the same scene. It is especially useful near doorways, windows, driveways, loading entrances, and other high-contrast locations where backlighting can reduce visible detail.

Intelligent Human-Based Detection

Supported events include cross-line detection, human-body-based intrusion detection, motion detection, tampering alarms, and audio detection. Human-based filtering can help focus supported alerts on meaningful activity rather than ordinary motion within the scene.

MicroSD Recording up to 256GB

An optional MicroSD card up to 256GB provides onboard edge storage. It can be used for supported local event recording or as an additional recording layer when used with compatible network equipment.

IP67 Metal Indoor / Outdoor Housing

The metal housing is IP67 weather rated and designed to operate from approximately -22°F to 140°F. It also includes 4kV surge protection for dependable use in demanding indoor or outdoor installations.

Record Locally & View Remotely with No Required Monthly Fees

Connect the SV-B8IR-N to a compatible SureVision NVR to add continuous or motion recording, local hard-drive storage, recorded playback, event search, video export, and centralized camera management.

Free compatible mobile and desktop software allows authorized users to remotely access live video and supported system functions without mandatory cloud-storage subscriptions.
