DS-2CD2743G2-LIZS2U/SL

Manufacturer reference

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

Image, lens and lighting

Device class

4 MP AcuSense motorized varifocal dome camera with strobe light and audible warning

Maximum image resolution

2688 × 1520 (4 MP).

Image sensor

1/3-inch progressive-scan CMOS.

Lens

Motorised 2.8 to 12 mm varifocal lens. Lens adjustment does not establish motorised pan, tilt, auto-tracking or a PTZ camera.

Field of view

Horizontal: 102.4° to 31.2°; vertical: 54.7° to 17.6°. These ranges change with focal length; they are not a fixed view for every lens setting.

Full-resolution main stream

At 2688 × 1520: 25 fps in 50 Hz mode, 30 fps in 60 Hz mode.

Other main-stream resolutions

1920 × 1080 and 1280 × 720: 25 fps at 50 Hz or 30 fps at 60 Hz.

Main-stream compression

H.265, H.264, H.264+ and H.265+ are listed for the main stream. Check recorder, firmware and encoding settings separately.

Third stream

Up to 10 fps at 1920 × 1080, 1280 × 720, 640 × 480 or 640 × 360. The manufacturer explicitly makes third-stream support conditional on settings.

Supplementary lighting

IR and white light with smart supplementary-light control are listed. Lighting performance depends on the scene and settings.

Supplementary-light range

Up to 30 m in this manufacturer sheet. This is a lighting reference, not a face-identification, recognition or detection-distance guarantee.

Wide dynamic range

120 dB WDR is listed. Actual image results depend on the scene, exposure and configuration.

Lens aperture and iris

F1.6 aperture and a fixed iris are listed. This does not establish an adjustable-iris lens.

Connectivity, audio and event functions

Built-in microphones

Arrayed dual microphones are listed. They do not by themselves establish a built-in speaker or every two-way-audio workflow.

Audio input and output

One line input and one line output, each maximum 3.3 Vpp. Input impedance: 4.7 kΩ; output impedance: 100 Ω. These are line interfaces, not loudspeaker-power outputs.

Network connection

One RJ45 10/100 Mbit/s self-adaptive Ethernet port; no gigabit port is established.

Removable storage

A microSD/microSDHC/microSDXC card slot supports up to 512 GB. Card inclusion, endurance, compatibility and retention require separate confirmation.

Integration references

Profile S and Profile G network video interface, ISAPI, SDK and ISUP are listed. Confirm the actual firmware, recorder and client workflow; this is not universal interoperability approval.

Simultaneous live view

Up to six live-view channels are listed. This is not an NVR input-channel capacity or a guarantee of network performance.

User accounts

Up to 32 users with administrator, operator and user levels. Account capacity is separate from simultaneous live view.

Motion events

Motion events can target human and vehicle types; video-tampering and exception events are also listed. This is not facial identity recognition, number-plate reading or guaranteed alarm accuracy.

Perimeter events

Line crossing and intrusion with human/vehicle target classification are listed. Confirm field of view, scene and event settings for the actual application.

Reset control

A reset key is listed.

Built-in speaker

One 1.5 W speaker is listed. The stated maximum sound-pressure level is 120 dB at 10 cm; it is not a 1 m or site-wide audibility guarantee.

Active warning

Audible warning and white strobe-light flashing are listed in the event linkage. Confirm configuration and local use requirements; this is not a guarantee of deterring an intruder.

Power, housing and environment

Operating conditions

Startup and operation: -30 to 60 °C, humidity at most 95%, non-condensing. Cable joints, mounting and external power equipment require their own suitable protection.

DC power input

12 V DC ±25%; 1.35 A; maximum 16.2 W. The sheet lists reverse-polarity protection and a 5.5 mm coaxial plug. Do not apply mains voltage.

PoE power

IEEE 802.3at, Class 4; maximum 18 W. Size the PoE switch budget for the required camera count; DC and PoE maximum figures are not interchangeable.

Enclosure protection

IP67 and IK10 are listed for the camera. These do not approve every assembled installation, connector or corrosive environment.

Housing material

Aluminium alloy body is listed for the camera housing.

Camera weight

Approximately 1531 g, as listed for the camera rather than its packaged weight.

Corrosion suitability

The sheet assigns no specific anti-corrosion protection to this model. IP67 does not establish marine or chemical-environment suitability.

Camera dimensions

Diameter 121.5 mm × 97.6 mm, matching the body drawing. Verify mounting clearances and accessories separately.

Selection notes

• These references apply to the linked manufacturer datasheet. Confirm the complete lens, colour and any hardware or regional suffix, installed firmware and actual supplied unit before selection.
• Motorised varifocal refers to the lens. Mechanical angle adjustment does not establish PTZ head movement, continuous rotation or automatic tracking.
• Use the complete requested ordering code and quantity. Black, T, lens and regional variants are not automatically merged into this reference.
• Lighting range, WDR and event classification are manufacturer references, not guaranteed site recognition or alarm performance. Verify recording mode, power budget and connected equipment.
• ISD supplies products only. Stock, price, lead time, actual accessories and local warranty require a separate quotation and confirmation.
