Maximum image resolution

3840 × 2160 pixels; manufacturer 8 MP class.

Shutter-time range

1/3 s to 1/100,000 s; exposure settings affect motion and low-light results.

Fixed-lens options

Depth-of-field reference

2.8 mm: 1.7 m to infinity; 4 mm: 2.6 m to infinity; 6 mm: 5.8 m to infinity. Lens-specific references, not guaranteed identification distances.

Supplementary light

IR and white-light supplementary illumination, up to 40 m in the manufacturer reference. Scene, exposure and target conditions affect usable coverage.

IR wavelength

850 nm infrared reference, distinct from the visible white light.

Dynamic range

120 dB WDR manufacturer reference.

Signal-to-noise ratio

At least 52 dB in the manufacturer reference.

Image enhancement

BLC, HLC and 3D DNR are listed; not guaranteed identification in every scene.

Video, audio and network

Full-resolution main stream

20 fps at 3840 × 2160 under both 50 Hz and 60 Hz configurations; not a 25/30 fps full-resolution claim.

Lower-resolution main stream

50 Hz: 25 fps; 60 Hz: 30 fps at 3200 × 1800, 2688 × 1520, 1920 × 1080 or 1280 × 720 as listed.

Sub-stream reference

50 Hz: 25 fps; 60 Hz: 30 fps at 1280 × 720, 640 × 480 or 640 × 360 as listed.

Third-stream reference

10 fps at 1920 × 1080, 1280 × 720, 640 × 480 or 640 × 360 under both frequency configurations, only under certain settings. Confirm the actual stream configuration.

Main-stream compression

H.265, H.264, H.264+ and H.265+ are listed for the main stream. Check the actual recorder/client mode.

Sub-stream compression

H.265, H.264 and MJPEG are listed for the sub-stream.

Third-stream compression

H.265 and H.264 are listed for the third stream, only under certain settings. No plus-codec entitlement is inferred on that stream.

Video bitrate range

32 Kbps to 16 Mbps configurable video bitrate; not guaranteed internet throughput or recording duration.

Region of interest

One fixed ROI region is listed for the main stream and sub-stream.

Scalable video coding

SVC is listed for H.264 and H.265 encoding; check actual recorder/client capabilities.

Privacy masks

Eight programmable polygon privacy masks; check actual configuration.

Ethernet interface

One self-adaptive 10/100 Mbps RJ45 port; not Gigabit Ethernet.

On-board storage

A microSD/microSDHC/microSDXC slot up to 512 GB is listed for this exact model. A memory card is not assumed included; capacity alone does not determine retention days.

Reset key

A reset key is explicitly listed for this exact model.

Protocol-profile reference

The manufacturer lists Profiles S and G for Open Network Video Interface, plus ISAPI, SDK and ISUP. Confirm actual recorder/VMS functions; this is not universal interoperability.

Network-storage reference

NAS using NFS or SMB/CIFS and Auto Network Replenishment (ANR) are listed. Check actual recorder, storage and configuration; no storage service is assumed included.

Memory-card security condition

The source ties memory-card encryption and health detection to high-end Hikvision memory cards. Do not assume every card provides those functions; confirm the actual card and firmware.

Built-in microphone

The -2U row lists a built-in dual array microphone for this LI2U model.

Audio compression

G.711, G.722.1, G.726, MP2L2, PCM, MP3 and AAC-LC are listed for the -2U model. Check actual recorder/client support.

Audio sampling

8, 16, 32 or 48 kHz sampling is listed for the -2U model; not video frame rate.

Audio noise filtering

Environment noise filtering is listed for the -2U model; no field-performance guarantee is implied.

Target-filtered motion events

Motion detection supports triggering by specified human or vehicle target types; video tampering and exceptions are listed. This does not establish identity recognition.

Perimeter event reference

Line crossing, intrusion, region entrance and region exiting are listed with human/vehicle target-trigger filtering. Confirm scene and recorder configuration; no detection-accuracy guarantee.

Power, environment and selection

DC power input

12 V DC ±25%, 0.5 A; max. 6 W. Reverse-polarity protection and a 5.5 mm coaxial power plug are listed; confirm the regulated supply.

PoE power input

IEEE 802.3af, Class 3; max. 7.5 W reference. Size the supplying switch for connected loads; this camera is not a PoE power output.

Housing material

Metal is listed as the material; this does not establish corrosion or impact resistance.

Body dimensions

Diameter 74.4 mm × overall length 176.3 mm. The exact-model dimension diagram agrees with the table; fixing circles and package dimensions are separate.

Package dimensions

234 mm × 120 mm × 117 mm package reference; not the camera body or fixing layout.

Net weight reference

Approx. 515 g in the camera weight row; not packaged shipping weight.

Packaged weight reference

Approx. 760 g in the packaged weight row; verify actual packing and contents before shipping.

Operating conditions

Startup and operation: -30 to 60 °C, humidity 95% or less, non-condensing. Check actual site environment and power.

Storage conditions

-30 to 60 °C, humidity 95% or less, non-condensing, in the storage-conditions row.

Ingress protection

IP67 is listed; not impact resistance, anti-corrosion performance or approval for every wet location.

Anti-corrosion category

No specific anti-corrosion protection is assigned in the manufacturer application table. Check corrosive or coastal-site suitability separately.

Optional mounting references

Optional DS-1275ZJ-SUS pole mount, DS-1280ZJ-XS junction box and DS-1276ZJ-SUS corner mount are listed. They are not included or an ISD installation service; verify the exact mounting assembly.

Selection notes

• These references apply to the complete printed DS-2CD2083G2-LI2U model and its listed 2.8 mm, 4 mm or 6 mm fixed-lens choices. Confirm the supplied full label, region, hardware, firmware, lens, power and recorder functions.
• The current technical references are not confirmation of stock, price, ETA, local warranty, authorisation, current firmware or Malaysian compliance.
• Lens options, memory cards, power supplies, mounts, cables, software and recording services are not assumed included. ISD supplies products only.
• Up-to illumination distance and reference focus/DORI values are not guaranteed identification distance or classification accuracy. Fixed-lens orientation adjustment is not motorized PTZ.
• Third-stream availability depends on actual settings. Confirm exact housing, mounting clearance, lens, power, card, recorder and integration requirements before ordering.
• Only the explicitly printed -2U audio rows apply to DS-2CD2083G2-LI2U; they do not transfer to DS-2CD2083G2-LI.
