DS-2CD1147G3-LIU

Manufacturer reference

Manufacturer details describe the cited version. Confirm the exact unit and intended system.

Imaging, lens and illumination

Device class

4 MP ColorVu 3.0 fixed dome network camera

Image sensor

1/3-inch progressive-scan CMOS optical format; not a measured sensor diagonal.

Low-light conditions

Colour 0.0005 lux at F1.0 with AGC on; 0 lux requires supplementary light. Not a guaranteed target-recognition result.

Shutter-time range

1 s to 1/100,000 s. Exposure affects motion and low-light results.

Day and night modes

An IR cut filter and day, night, auto and scheduled switching are listed. Colour performance still depends on the scene and light.

Manual angle adjustment

Pan 0–355°, tilt 0–75°, rotate 0–355°. Installation adjustment, not motorised PTZ.

Fixed-lens choices

2.8 mm or 4 mm fixed focal ordering alternatives. Select the lens; not optical zoom or two included lenses.

2.8 mm field of view

With the 2.8 mm lens: horizontal 101.5°, vertical 54.6°, diagonal 122.1°.

4 mm field of view

With the 4 mm lens: horizontal 84.1°, vertical 45.6°, diagonal 99.1°.

Aperture

F1.0 is listed; the low-light measurement also requires the stated AGC and lighting conditions.

Lens mount and iris

M12 lens mount with a fixed iris. No approved interchangeable-lens list is inferred.

Depth-of-field reference

2.8 mm: 1.7 m to infinity. 4 mm: 1.6 m to infinity. Match the selected lens and target distance.

DORI reference

2.8 mm: detect 63 m, observe 25 m, recognise 12 m, identify 6 m. 4 mm: 77 m, 30 m, 15 m and 7 m respectively. Planning references, not field identification guarantees.

Supplementary-light reference

IR and white supplementary light, rated up to 30 m. This is not guaranteed identification at 30 m.

IR wavelength

850 nm IR wavelength is listed.

Smart light control

Smart supplementary-light control is listed. Confirm the required light mode and configuration; this is separate from a deterrent strobe or speaker.

Streams, audio and interfaces

Video compression

Main stream: H.265+, H.265, H.264+ or H.264. Sub-stream: H.265, H.264 or MJPEG. Confirm recorder and client support.

Video bitrate

32 Kbps to 8 Mbps, with CBR/VBR control listed. Not a fixed retention-duration guarantee.

Sub-stream frame rates

50 Hz: 25 fps. 60 Hz: 24 fps. Listed sub-stream sizes are 1280 × 720, 640 × 480 or 640 × 360. Do not silently replace 24 with 30 fps.

Region of interest

One fixed ROI region is listed for the main stream and sub-stream. ROI is not an additional video stream.

Dynamic range

120 dB WDR is listed; not a guarantee of recognition in every backlit scene.

Image enhancement

BLC, HLC and 3D DNR are listed.

Privacy masks

Four programmable polygon privacy masks.

Microphone reference

One built-in microphone with mono audio is listed. This does not establish a speaker, two-way talk or an external audio connector.

Audio compression

G.711ulaw, G.711alaw, G.722.1, G.726, MP2L2, PCM, AAC-LC and MP3 are listed. Confirm stream and client compatibility.

Audio sampling

8 kHz or 16 kHz audio sampling is listed; not a claim for every codec configuration.

Audio noise filtering

Environmental noise filtering is listed. It does not establish a noise-free or forensic audio guarantee.

Ethernet interface

One self-adaptive 10/100 Mbps RJ45 Ethernet port.

Network protocol reference

The source lists TCP/IP, ICMP, DHCP, DNS, HTTP, RTP, RTSP, RTCP, NTP, IGMP, UDP, QoS, FTP and SMTP. This is not an enabled-service claim.

Live-view reference

Up to six simultaneous live-view channels are listed. Viewing sessions, not six camera inputs.

User accounts

Up to 32 users with administrator, operator and user levels. Separate from the six live-view-session limit.

Integration interfaces

The API row names ISAPI and SDK, plus Open Network Video Interface Profiles S and T. Profile G is explicitly limited to F models; no certification or universal compatibility is inferred.

Motion-event reference

Motion detection with specified person/human and vehicle target types, video tampering and exception events are listed. Configure and test the camera, recorder and client together.

Power, physical limits and selection

DC power reference

12 V DC ±25%, 0.5 A, maximum 6 W, with Ø5.5 mm coaxial plug and reverse-polarity protection. Confirm the supply.

PoE power reference

IEEE 802.3af Class 3, maximum 7.5 W. Alternative to DC; do not add the DC and PoE ratings.

Body materials

Metal base with plastic cover. No alloy grade or marine treatment is inferred.

Body dimensions

Diameter 121.5 mm × height 97.6 mm. The table and whole body drawing agree; the 104.7 mm mounting circle and hole sizes are separate.

Weight reference

Approximately 550 g body weight and 800 g with packaging. Not a mounted-assembly or confirmed shipping weight.

Operating and storage conditions

-30 to +60 °C, humidity at most 95%, non-condensing, are listed for storage and startup/operation. Confirm the actual mounting and exposure.

Protection reference

IP67 under IEC 60529-2013 and IK08 under IEC 62262:2002 are listed. Not a guarantee for every mount, cable assembly or impact.

Optional mounting examples

The optional list includes DS-1280ZJ-DM46 junction box, DS-1271ZJ-120 pendant and DS-1272ZJ-120B wall-mount examples. Confirm the complete assembly; not included or an ISD installation service.

Selection notes

• This DS-2CD1147G3-LIU reference uses its complete literal entry and the manufacturer family document. Lens alternatives do not merge identities. Confirm the actual lens, hardware, region, firmware, recorder, power and supplied items; other suffixes are not interchangeable.
• Confirm the pixel maximum and main-stream operating modes for the supplied edition before system sizing; no conflicting values are assigned here.
• Manufacturer references do not confirm stock, price, ETA, local warranty, authorisation, current support or Malaysian compliance. ISD supplies products only.
• Cards, power equipment, brackets, adapters and recording services are not assumed included. Microphone, supplementary light and motion detection do not establish a speaker, strobe, two-way talk or identity recognition.
