Dahua SD4D425MB-HNR 4MP 25x Smart Dual Light PTZ Camera

SD4D425MB-HNR is a 4 MP, 25x optical zoom PTZ dome from the Dahua WizSense SD4 series. It has a 5 to 125 mm lens, infrared and warm light out to 100 m, WizTracking auto tracking, IP67 protection and TVS 6000 V lightning and surge protection, and it can run on a single 802.3at PoE cable.

A compact PTZ for yards, roads and building perimeters

A PTZ covers areas a fixed camera cannot: the endless 360 degree pan, tilt from -15 to +90 degrees with 180 degree auto flip, and a 25x lens that narrows from 54.1 to 3.4 degrees horizontal. The datasheet DORI table gives 100 m detect at wide and 2,500 m detect, 1,000 m observe, 500 m recognize and 250 m identify at tele.

Auto Tracking follows a moving target by controlling pan, tilt and zoom, triggered manually or by IVS rules such as tripwire or intrusion; Auto Patrol links the dome to the target position. Smart Dual Light switches to full-colour warm white when a target appears and returns to infrared afterwards.

Selection and ordering guide

The datasheet ordering code is DH-SD4D425MB-HNR (4MP 25x Smart Dual Light WizSense Network PTZ Camera). The power adapter is listed as optional, so say in your enquiry whether you will power from PoE or 12 VDC.

If you need longer reach, the SD6AL445GB-HNV in this catalogue has a 45x lens and a laser light reaching 550 m. If a fixed camera is enough for the view, the bullet and eyeball models are lower in complexity (derived comparison).

Installation and operation notes

Mounting accessories listed by Dahua include the PFB300C ceiling, PFB301S-E plane, PFA150 pole, PFA151 corner and PFB303S parapet brackets, the PFA111 adapter, and the PFA126 waterproof and PFA120 junction boxes. The installation guide and installation manual for speed domes and PTZ cameras and the Web 5.0 PTZ user manual are available on the Dahua page. Program presets, tours and idle motion after mounting so the dome returns to a useful view.

Applications in Oman and the GCC

The wide range of -40 to +70 C and IP67 enclosure with TVS 6000 V protection are relevant for exposed pole and rooftop mounting in hot, dusty conditions with lightning risk. Typical uses are yard and tank-farm overview, gate and road monitoring, car parks, construction sites and building perimeters where one dome replaces several fixed cameras.
