Hikvision AcuSense 5 MP IR Fixed Bullet Network Camera DS-2CD3T56G2-4IS

The DS-2CD3T56G2-4IS is the 5 MP fixed-lens bullet in Hikvision’s 3-Series AcuSense line, and it is the point in the range where a camera stops being only an image source and becomes an input to the system. AcuSense runs person and vehicle classification on the camera itself, and the datasheet confirms the audio and alarm interfaces on the current revision — so the unit can act on what it sees at the pole, not just push a stream back to a recorder and hope somebody is watching it.

For an integrator, that is the whole argument for this price step. A cheaper camera gives you pictures. This one gives you a classified event you can wire into something — a relay, a speaker, a local siren. The recorder still gets the video, but the decision no longer has to travel the length of the network before anything happens on site.

Where it earns its place on a site

Fixed lens, fixed bullet, IR. That is a perimeter camera and it should be specified as one — a run of fence, a yard boundary, a loading approach, a car park edge, where the scene never changes and nobody will adjust a zoom after commissioning. Fixed optics remove a moving part and a re-focus service call from a camera that will sit on a mast for years.

5 MP is the unfashionable resolution, and that is precisely why it suits perimeters: more detail than 4 MP where you need to tell a person from a shadow, and materially less storage and bandwidth than 8 MP across twenty or thirty channels. Where the recorder and the disks are already costed, that gap is a line item you can feel.

The AcuSense classification is what makes the line viable outdoors here. Blowing dust, moving branches, stray animals and headlight wash turn a well-built perimeter into an alarm log nobody reads by the second week. Filtering to person and vehicle at the edge is the difference between a system the guard trusts and a system the guard mutes.

Before you order — three things to confirm

• Lens and coverage. Field of view is decided at purchase, not at commissioning. Send us the run length and mounting height and confirm the focal length against the datasheet before ordering in quantity.
• Whether you are actually using the audio and alarm terminals. If nothing is being wired into them, a simpler model in the range may be the correct specification and the cheaper one.
• Recorder channel and licence headroom. Confirm your NVR can take the added channels at the resolution you intend to record, and that any smart-event handling you want is supported on your recorder generation.

Full manufacturer datasheet available on request — call 16454. We send the current revision for the stock batch you are buying rather than a figure copied off a listing, which matters when a consultant checks the submittal.

Compatibility

A standard Hikvision network camera: it drops into Hikvision NVRs and the usual Hikvision desktop and mobile management software. If you are integrating with a third-party VMS or driving access control from the alarm terminals, tell us the platform and we will confirm the path against the datasheet before you commit the order.

• Manufacturer-supplied mounting hardware and documentation as packed by Hikvision

Common questions on this model

Can it trigger something on site without the recorder?
That is the point of this variant. AcuSense classifies at the edge and the datasheet confirms the audio and alarm interfaces on the current revision, so a classified event can drive a local output. Confirm terminal count and ratings on the datasheet before designing the wiring.

Why 5 MP instead of 8 MP?
Storage and bandwidth across a multi-channel perimeter. On a single-camera job the argument is weak; on a thirty-camera fence it is the deciding factor.

Do you supply project quantities and pricing?
Yes — this is a channel line for contractors and integrators. Send the bill of quantities and we will price cameras, recorder and accessories as one package. Call 16454.
