Hikvision DS-2CD2766G2H-IPTRZS2U/SL 6MP AcuSense PTRZ Varifocal Dome

Hikvision DS-2CD2766G2H-IPTRZS2U/SL — 6 MP AcuSense PTRZ dome with strobe and siren

The DS-2CD2766G2H-IPTRZS2U/SL is the 6 MP member of Hikvision's PTRZ dome family, and it combines the two things that usually mean two separate cameras: a lens assembly that can be pan, tilt, rotate and zoom adjusted entirely from the software, and an active deterrence package with a white strobe light and an audible warning through a built-in speaker.

AcuSense deep-learning classification separates people and vehicles from foliage, rain, shadows and animals, so line crossing, intrusion, region entrance and region exiting trigger only on real targets. Face capture is supported.

What PTRZ actually means here — and its one limit

Unlike a fixed dome, the whole optical block repositions remotely: pan 0° to 350°, tilt 0° to 85°, rotate 0° to 350°, plus the 2.8–12 mm motorised zoom. An installer mounts the camera, then frames the shot from a laptop rather than from the top of a ladder — and the view can be re-aimed months later without another visit.

It is worth being clear about what this is not. This is not a PTZ. Hikvision rates the positioning mechanism at a maximum of 1,000 cycles. It is designed for commissioning and the occasional re-aim, not for an operator to drive it around all day. If you need continuous operator control or patrol tours, you need a true PTZ camera.

Coverage: wide or long, chosen in software

Hikvision's published DORI figures show how much the zoom changes the camera's job. Wide: detect 74.3 m, observe 29.5 m, recognise 14.9 m, identify 7.4 m. Tele: detect 183.3 m, observe 72.8 m, recognise 36.7 m, identify 18.3 m. The night limit is the 40 m IR range — beyond that, the tele figures depend on ambient or added lighting.

Imaging

• 1/1.8" progressive scan CMOS, 3200 × 1800 at 25 fps (50 Hz)
• Max. F1.2 aperture, 0.0008 lux in colour, 0 lux with IR on
• 120 dB WDR for entrances, forecourts and loading areas shot into strong backlight
• 40 m Smart Supplement Light IR at 850 nm; depth of field from 1 m
• BLC, HLC and 3D DNR; 4 programmable polygon privacy masks

Deterrence and audio

• White strobe light and audible warning triggered directly by the camera's own event rules — no recorder required to deter
• Arrayed dual built-in microphones and a built-in speaker rated 97 dB at 10 cm, for two-way audio through iVMS-4200, Hik-Connect or HikCentral
• 1 audio in (line in), 1 audio out (line out), two-core terminal block
• 1 alarm in, 1 alarm out (max. 24 VDC/24 VAC, 1 A)

Note the speaker here is 97 dB, where the DS-2CD2T86G2H-IS2U/SL bullet manages 120 dB. This camera is better suited to a courtyard or entrance than to being heard across an open yard.

Recording, storage and network

• H.265+/H.265/H.264+/H.264, 32 Kbps to 16 Mbps
• microSD/SDHC/SDXC to 512 GB, plus NAS (NFS, SMB/CIFS) and ANR to backfill footage recorded during a network outage
• ONVIF Profile S/T/G, ISAPI, SDK and ISUP; up to 6 simultaneous live view channels
• The Ethernet port is 10/100, not gigabit

Power, build and environment

• PoE IEEE 802.3at Class 4, max. 18 W — not 802.3af. The positioning motors, strobe and speaker together need an at port.
• Or 12 VDC ± 25%, 1.35 A, max. 16 W. The DC connection is a two-core terminal block, not a barrel jack.
• Metal housing rated IK10 and IP66. Worth flagging: IP66 is one step below the IP67 carried by most of the fixed G2H cameras — it is rated against powerful water jets rather than temporary immersion. Fine for normal external mounting; consider the rating if the position is genuinely exposed or subject to flooding.
• Ø155 mm × 140.4 mm, approx. 840 g
• −30 °C to 60 °C, humidity 95% or less non-condensing

What you'll need with it

• An 802.3at PoE switch or NVR port, or a 12 VDC supply terminated to bare conductors
• An AcuSense-capable Hikvision NVR to carry human/vehicle classification through to smart search on the recorder
• A microSD card for edge recording or ANR backfill — not supplied
• A junction box or pendant mount sized for the Ø155 mm housing

Frequently asked questions

Can an operator drive this camera around like a PTZ?

No. The positioning mechanism is rated for a maximum of 1,000 cycles and is intended for commissioning and occasional re-aiming. For continuous operator control, specify a PTZ.

Do the strobe and siren work without a recorder?

Yes — the camera's own event rules drive both.

Is this a ColorVu camera?

No. This is AcuSense with infrared night vision, so the image goes to black and white in darkness. The white light is a strobe for deterrence, not continuous illumination for colour night video.

Will it work on a third-party NVR?

It supports ONVIF Profile S, T and G, so it will record on most ONVIF recorders. AcuSense classification, strobe and audio are best supported on Hikvision recorders.
