§ 01Overview

What the DH-SD4E425GB-HNR-A-PV1 is

The Dahua DH-SD4E425GB-HNR-A-PV1 is a 4MP WizSense network PTZ camera combining 25× optical zoom, Auto Tracking 3.0 and active sound-and-light deterrence for large outdoor surveillance areas.

Its 5–125mm motorised lens moves from a broad 51.9° horizontal view to a narrow 3.0° view, while smart dual illumination provides up to 100 metres of infrared coverage and 50 metres of white light.

Red and blue warning lights work with 11 selectable alarm sounds and imported custom audio to respond visibly and audibly to configured events.

SMD 4.0, AcuPick, face detection and human or vehicle perimeter classification support more targeted alarms and searches.

Continuous 360° pan, PoE+, local microSD storage and IP66 protection support professional commercial installations.

§ 02Engineering

DH-SD4E425GB-HNR-A-PV1 specifications

- 25× Optical Zoom: 5–125mm motorised lens, 51.9°–3.0° horizontal field of view for wide-area overview to close inspection.
- Active Sound and Light Deterrence: Red/blue warning lights with 11 selectable alarm sounds and custom audio import for event-linked response.
- 100m IR and 50m White Light: Smart dual illumination for long-range IR monitoring and visible white-light colour imaging after dark.
- Auto Tracking 3.0: Rule-triggered or manual tracking using pan, tilt and zoom to keep supported targets in view.

- Face Detection: Supports face detection, tracking, snapshots and attribute extraction (gender, age, glasses, mask, expressions).
- Rugged IP66 Protection: IP66, TVS 6000V lightning resistance, surge protection and -40°C to +65°C operation.

§ 04Why choose this

Built for the way you actually use the DH-SD4E425GB-HNR-A-PV1

25x Optical Zoom Coverage

The 5–125mm motorised lens moves from a broad 51.9° horizontal overview to a narrow 3.0° view for close inspection across large sites.

Active Sound and Light Deterrence

Red and blue warning lights combine with 11 selectable alarm sounds and custom audio import to provide immediate event-linked deterrence.

Auto Tracking 3.0

Rule-triggered or manual tracking uses pan, tilt and zoom movement to keep supported moving targets in view and capture a more detailed trajectory.

Smart Dual Illumination

100m IR supports long-range black-and-white monitoring; 50m white light supports colour imaging and visible deterrence after dark.

WizSense Human and Vehicle Analytics

SMD 4.0, perimeter protection and AcuPick focus supported searches and alarms on people and motor vehicles.

Rugged IP66 Protection

IP66 construction, TVS 6000V lightning resistance, surge protection and -40°C to +65°C operation for demanding outdoor installations.

§ 05Where it fits

Right at home in these scenarios

Commercial Car Parks

Use 25× optical zoom, Auto Tracking 3.0 and active warnings to monitor vehicle lanes, pedestrian areas and boundary incidents.

Warehouses and Logistics Yards

Presets, tours, 100m IR and human or vehicle classification support loading docks, gates, external storage and perimeter approaches.

Construction and Remote Sites

Red/blue lights, sound warnings and app or NVR event handling can provide visible deterrence where immediate on-site response is limited.

Industrial Compounds

IP66 protection, surge resistance and broad temperature tolerance support demanding outdoor locations when earthing and mounting are correctly engineered.

Retail and Shopping Precincts

High-speed PTZ movement, face detection and intelligent event filtering support active monitoring of entrances, service lanes and public areas.

Schools and Campuses

Long-range overview, tracking and configurable deterrence can support gates and open grounds when privacy, audio and warning-light policies are properly managed.

§ 07Questions

Frequently asked about the DH-SD4E425GB-HNR-A-PV1

Q.01

How does active deterrence work on the Dahua DH-SD4E425GB-HNR-A-PV1?
The camera can activate red and blue warning lights and play one of 11 built-in alarm sounds when a configured event occurs. Custom warning audio can also be imported. The lights can flash for 5 to 30 seconds at a selected frequency. Deterrence performance depends on correct rule placement, target classification, speaker volume, site noise, camera position and local operating requirements.
Q.02

Does the camera provide white light as well as infrared?
Yes. Dahua specifies infrared illumination up to 100 metres and white-light illumination up to 50 metres. The dual-light system can support colour video when white light is active, while IR supports discreet black-and-white night monitoring. Practical range depends on zoom position, target reflectivity, rain, fog, nearby surfaces and mounting height.
Q.03

How much detail does the 25× optical zoom provide?
The 5–125mm motorised lens provides 25× optical zoom, changing the horizontal field of view from approximately 51.9° to 3.0°. Optical zoom places more image detail on distant subjects than digital enlargement, but recognition performance still depends on distance, lighting, atmospheric conditions, target movement and mounting height.
Q.04

What is Auto Tracking 3.0?
Auto Tracking 3.0 controls pan, tilt and zoom to keep a detected moving target within the camera view. Tracking can be started manually or linked to configured intelligent rules. The camera can zoom towards the target and follow its movement.
Q.05

Which intelligent analytics are supported?
The camera supports SMD 4.0, AcuPick, face detection and perimeter-protection rules with human and vehicle classification. Listed IVS functions include tripwire, intrusion, fence crossing, loitering, abandoned or missing object, fast movement, parking and people gathering.
Q.06

Does this PTZ have a built-in microphone and speaker?
The camera has a built-in speaker used for active-deterrence sound warnings, and Dahua lists one audio input and one audio output. A built-in microphone is not stated in the official specification, so external audio equipment may be required for listening or two-way communication.
Q.07

Can the camera use PoE and record to a microSD card?
Yes. The DH-SD4E425GB-HNR-A-PV1 supports IEEE 802.3at PoE+ or 12V DC at 3A, with a listed maximum consumption of 13W when illumination, heater, PTZ movement and speaker are operating. It also supports microSD storage up to 512 GB, FTP or SFTP and NAS.
