The DS-2CD2083G2-I is an 8MP AcuSense fixed bullet network camera designed for commercial perimeter monitoring that requires detailed 4K video, human and vehicle classification, and outdoor durability.
Its 4 mm fixed lens provides a narrower 87° horizontal field of view than the 2.8 mm version, making it suitable for entrances, vehicle gates, loading docks, driveways, and other areas that require more focused coverage.
AcuSense technology helps supported motion, line crossing, and intrusion events focus on people and vehicles. Smart IR provides nighttime visibility up to 40 meters, while 120 dB WDR helps preserve detail in backlit scenes.
The camera also supports H.265+ compression, microSD storage up to 512 GB, IEEE 802.3af PoE, ONVIF integration, and IP67 weather protection.

Find answers to common questions about compatibility, installation, infrared night vision, recording storage, and AcuSense human and vehicle classification.
Where is the DS-2CD2083G2-I commonly installed?
The DS-2CD2083G2-I is commonly installed at warehouse entrances, vehicle gates, loading docks, office buildings, parking access points, and commercial property perimeters that require focused outdoor monitoring.
Is the DS-2CD2083G2-I suitable for warehouse perimeter monitoring?
Yes. Its 8MP resolution, 4 mm fixed lens, human and vehicle classification, 40-meter infrared illumination, and IP67-rated housing make it suitable for warehouse entrances, loading areas, exterior walls, and perimeter access points.
Can this camera monitor vehicle gates and loading docks?
Yes. The 4 mm lens provides more focused coverage than a wider 2.8 mm lens, making it useful for vehicle gates, delivery lanes, loading docks, driveways, and controlled access points.
Can this camera be used around office and retail properties?
Yes. It can monitor office entrances, employee parking access, delivery areas, storefront exteriors, service entrances, and exterior walkways around commercial properties.
Who should choose the DS-2CD2083G2-I with a 4 mm lens?
This version is suited to security installers, system integrators, facility managers, property managers, IT teams, and business owners who need focused 8MP coverage for outdoor entrances, gates, and perimeter areas.
What is the benefit of AcuSense human and vehicle classification?
AcuSense classification helps supported motion, line crossing, and intrusion events focus on people and vehicles. This can make event review more efficient by reducing attention given to unrelated scene movement.
What coverage does the 4 mm lens provide?
The 4 mm fixed lens provides an 87° horizontal field of view, a 46° vertical field of view, and a 105° diagonal field of view. It is suitable for more focused monitoring of entrances, gates, driveways, and access lanes.
Does the DS-2CD2083G2-I support Power over Ethernet?
Yes. It supports IEEE 802.3af PoE, allowing power and network data to be delivered through one Ethernet cable. It can also be powered by a compatible 12 VDC source.
Can the camera record locally and connect to an NVR?
Yes. The built-in microSD card slot supports local storage up to 512 GB. The camera also supports ONVIF Profile S and G, NAS storage, and integration with compatible network video recorders.
Does the DS-2CD2083G2-I include a built-in microphone?
No. The DS-2CD2083G2-I does not include a built-in microphone. The DS-2CD2083G2-IU is the related variant that includes a built-in microphone.
