Camera and fixed-lens selection

Device class: 4 MP Acusense Smart Hybrid Light Fixed Turret Network Camera
Maximum image resolution: 4 MP; 2688 x 1520. Frame-rate limits are a separate selection criterion.
Image sensor: 1/2.9-inch progressive-scan CMOS.
Lens choices: Fixed-focal 2.8 mm or 4 mm, F1.6, M12 mount. Specify one required lens; these are not a varifocal zoom or a promise that both lenses are supplied.
Lens field of view: 2.8 mm: H104, V57, D122 degrees; 4 mm: H84, V45, D100 degrees. Values depend on the selected fixed lens.
Minimum illumination: Colour: 0.005 lux at F1.6 with AGC ON; 0 lux with supplemental light. This is not a guaranteed site image or recognition distance.

Lighting, streams and image settings

Illumination reference: IR and white supplemental light, IR wavelength 850 nm, up to 30 m. The distance is an illumination reference, not an identification guarantee.
Supplemental-light modes: Four supplemental-lighting modes are stated on this family cover. Verify the actual firmware and selected operating mode.
Full-resolution main-stream frame rate: 2688 x 1520: 25 fps at 50 Hz or 30 fps at 60 Hz. Confirm the frequency mode and recorder settings.
Main-stream compression: H.265, H.264, H.264+ and H.265+ are listed for the main stream. Confirm the recorder/client and actual selected settings.
Sub-stream compression: H.265, H.264 and MJPEG are listed for the sub-stream. This does not resolve the independent main- or third-stream configuration.
Video bit-rate range: 32 Kbps to 8 Mbps. Actual recording storage depends on selected codec, scene, frame rate and settings.
Wide dynamic range: 120 dB WDR. This is a manufacturer imaging reference, not a guarantee for every backlit scene.
Image enhancement: BLC, HLC and 3D DNR are listed. Tune the actual scene and firmware settings.
Privacy masks: Eight programmable polygon privacy masks are listed; configure the required view on the actual camera.

Interfaces, events and audio

Ethernet interface: One RJ45 10/100 Mbps self-adaptive Ethernet port. This does not establish Gigabit Ethernet or a PoE output.
Network integration references: Open Network Video Interface profiles S and G, ISAPI, SDK and ISUP are listed. Confirm the exact recorder/client and firmware; this is not universal compatibility.
On-board storage: A microSD/microSDHC/microSDXC slot supports up to 512 GB. This is a capacity ceiling, not an included card or a retention-days promise.
Reset key: A reset key is listed for the family. Use the correct manual and authorised procedure for the actual equipment.
Network storage references: NAS using NFS or SMB/CIFS and ANR are listed. Confirm server permissions and recorder/network configuration; no storage appliance is included by this row.
Motion target classification: Motion events support specified human and vehicle target types. This is event classification, not a person identity, number-plate or false-alarm guarantee.
Perimeter event references: Line crossing and intrusion detection with human/vehicle target classification are listed. Confirm event configuration and receiver support.
Built-in microphone reference: Built-in arrayed dual-microphone is listed for the -2U model only.

Power, body and environment

DC power reference: 12 V DC +/-25%, 0.58 A, maximum 7 W. Check the correct supply; DC and PoE ratings are separate alternatives, not values to add together.
PoE power reference: IEEE 802.3af, Class 3, maximum 9 W. Check switch/injector standard and budget for the exact suffix; ordinary af and warning-model at requirements are not interchangeable.
Operating environment: Startup and operation: -30 to 60 degrees C, at most 95% RH, non-condensing. This is not permission for condensation or all outdoor environments.
Body dimensions: Diameter 127.3 mm x 96.3 mm height. Cross-checked against the body drawing; mounting-hole spacing and shipping carton are different dimensions.
Body material: Metal body. This does not establish a marine corrosion rating.
Ingress-protection reference: IP67 is listed. This is not a saltwater, chemical, corrosion or installed-system approval.
Corrosion selection limit: The typical-application section states no specific anti-corrosion protection. Do not treat the generic higher-level application examples as this camera approval.

Selection notes

Manufacturer family reference applies only to the complete listed model DS-2CD2343G2-LI2U. Confirm the exact lens, colour, hardware and firmware before selecting equipment; ordering variants are not interchangeable aliases.
DS-2CD2343G2-LI2U only: the source marks microphone/audio features -2U; do not transfer them to LI.
Specify the full original model, suffix, lens and quantity. Black, /SRB, hardware editions and regional ordering codes are not interchangeable aliases.
IR distance is not DORI identification distance. Human/vehicle classification is not facial identity or number-plate recognition.
Check the exact recorder/client, supply and firmware. Listed network profiles or events do not guarantee every system combination.
ISD supplies products only. Stock, price, ETA, package contents and local warranty are confirmed separately.
