Dahua SD6AL445GB-HNV 4MP 45x Starlight Laser PTZ Camera
Description
SD6AL445GB-HNV is a 4 MP, 45x optical zoom PTZ camera from the Dahua WizMind SD6AL series with a built-in laser illuminator that reaches 550 m, a wiper, auto tracking 3.0 and video metadata. It is the long-range surveillance dome for perimeters, ports, highways and large industrial sites where a person at 300 m must still be seen in the dark.
Long-range PTZ with laser illumination
The 3.95 to 177.7 mm lens narrows from 63.2 to 1.8 degrees horizontal. The datasheet DORI figures at the tele end are 3,555 m detect, 1,404.2 m observe, 711 m recognize and 355.5 m identify. Two IR illuminators and one laser illuminator provide light up to 550 m, switched by zoom priority, auto, manual or off.
A mechanical IR-cut filter, 120 dB WDR and a 1/2.8 inch STARVIS sensor handle bright glare and low light. A wiper clears the window, and the dome tilts from -20 to +90 degrees with 180 degree auto flip at pan speeds up to 240 degrees per second on presets.

Selection and ordering guide
The datasheet ordering code is DH-SD6AL445GB-HNV (4MP 45x Starlight Laser Network PTZ Camera). Included in the box per the datasheet: a DC36V/2.23A power adapter, the PFA111 mount adapter and the PFB303W bracket. Other brackets are optional.
Laser illumination and a 45x lens are intended for long distances; for areas within about 100 m the SD4D425MB-HNR in this catalogue has 25x zoom and a smaller 2.4 kg body (derived comparison).
Installation and operation notes
At 6.8 kg net the dome needs a rated bracket. The datasheet lists PFB300C ceiling, PFA150 pole, PFA151 plus PFB303W corner, PFA150 plus PFB300C horizontal pole, PFB301C ceiling, PFB301S-E plane and PFB303S parapet mounts. Power is 36 VDC (supplied adapter) or HI-PoE, with up to 45 W maximum draw, so check cable length and switch budget. Dahua publishes the Web 5.0 PTZ user manual and installation guides on the product page.
Applications in Oman and the GCC
Long fence lines, port and terminal yards, highway and junction monitoring, oil and gas site perimeters and large construction sites are typical long-range PTZ jobs. The -40 to +70 C range, IP67 and TVS 6000 V protection suit exposed rooftop and tower mounting; this camera is not listed as hazardous-area certified, so it is not for classified zones.
Compatible accessories and related items
Included: 36 VDC 2.23 A adapter, PFA111 mount adapter, PFB303W bracket. Optional: PFB300C, PFA150, PFA151 plus PFB303W, PFA150 plus PFB300C, PFB301C, PFB301S-E and PFB303S mounts. Record with a WizMind NVR such as NVR5832RH-XI.
