Description

The Dahua SDT4E425-4F-GB-A-PV1 combines panoramic and detail views in one PTZ camera. This X-Spans series camera provides 4MP resolution with 25x optical zoom and smart dual light technology for comprehensive surveillance.

Dual Camera System
The panoramic camera uses a 1/2.8″ 4MP F1.0 CMOS sensor. The detail camera features a 1/2.8″ 4MP STARVIS CMOS sensor. Two independent cameras work together for complete coverage.
Panoramic view maintains wide-area awareness. Detail camera zooms for close inspection. Combined operation provides context and detail simultaneously.

25x Optical Zoom
The detail camera includes 25x optical zoom capability. Zoom range spans 5-125mm focal length. Magnification enables detailed observation of distant subjects.
Optical zoom maintains image quality during magnification. Long-range viewing supports surveillance of large areas.

4MP Resolution Performance
Both cameras capture 4MP resolution footage. Maximum frame rate reaches 25/30fps at 4MP. High-resolution imaging ensures clear identification.
Resolution quality supports detailed monitoring requirements. Frame rate maintains smooth video playback.

Extended IR Illumination
Detail camera IR illumination extends up to 100 metres. Panoramic camera IR reaches 30 metres. Combined infrared coverage provides comprehensive night vision.
Long-range IR supports distant subject monitoring. Dual illumination systems cover both wide and zoomed views.

Smart Dual Light Technology
White light illumination reaches 50 metres on the detail camera. Panoramic white light extends 30 metres. Smart dual light switches between IR and white light based on conditions.
Full-colour night vision activates when needed. Infrared operation provides discreet monitoring.

Auto Tracking 3.0
Auto tracking 3.0 follows detected subjects automatically. Smart tracking maintains focus on moving targets. Tracking capability reduces manual PTZ control requirements.
Automatic subject following ensures continuous monitoring. Tracking technology adapts to subject movement patterns.

Perimeter Protection
Perimeter protection monitors defined boundary areas. Detection triggers alerts when subjects cross boundaries. Protection features focus on security zone monitoring.
Boundary monitoring provides targeted surveillance. Alert generation occurs during perimeter breaches.

Active Deterrence
Active deterrence features respond to detected threats. Deterrence systems warn or discourage intruders. Response capabilities support proactive security measures.
Deterrence activation occurs during security events. Active response supplements passive monitoring.

PTZ Functionality
Pan-tilt-zoom operation provides flexible camera positioning. PTZ control enables coverage of large areas. Movement capability expands monitoring range beyond fixed views.
Remote PTZ control adjusts camera positioning. Movement commands occur through system controls.

IP66 Weather Protection
IP66 rating protects against dust and water. Weatherproof design suits outdoor installation. Protection maintains camera operation in various conditions.
Environmental sealing guards internal components. Weather resistance extends camera lifespan outdoors.

Power Supply Options
Power options include PoE+ (802.3at) and 12VDC. PoE+ delivers power through network cables. Dual power options provide installation flexibility.
Maximum power consumption reaches 25W. Power requirements support continuous operation with all features active.

Audio Capabilities
Built-in speaker enables audio output. Audio input and output connections support two-way communication. Speaker integration provides announcements or warnings.
Audio features supplement video monitoring. Sound capability enhances security response options.

Alarm Integration
Alarm inputs and outputs connect external devices. Integration enables coordinated security responses. Alarm connections expand system capabilities.
Input channels receive signals from other devices. Output channels trigger external equipment.

Included Wall Mount Bracket
PFB305W wall mount bracket comes included. Mounting hardware supports wall installation. Bracket inclusion simplifies installation requirements.
Wall mounting provides stable camera positioning. Included bracket eliminates separate mounting hardware purchases.

X-Spans Series Technology
X-Spans series combines panoramic and PTZ views. Series technology provides comprehensive coverage solutions. Dual-camera design eliminates coverage gaps.
Series features support advanced surveillance applications. Technology integration enhances monitoring effectiveness.

Panoramic Overview
The 2.8mm panoramic lens provides wide-area coverage. Overview maintains awareness of entire monitored zones. Continuous wide view operates alongside detail camera.
Panoramic monitoring prevents blind spots. Wide coverage ensures complete area visibility.

Detail Camera Specifications
The 5-125mm detail lens enables close examination. STARVIS technology enhances low-light performance. Detail camera focuses on subjects of interest.
Close-up capability supports identification requirements. Enhanced sensitivity improves dark scene imaging.

Frequently Asked Questions
Q1: How does the dual camera system work?
A: The panoramic camera maintains wide-area coverage whilst the detail camera zooms for close inspection. Both cameras operate simultaneously, providing context and detail together. This eliminates blind spots during zoom operations.
Q2: What is Auto Tracking 3.0?
A: Auto Tracking 3.0 automatically follows detected subjects without manual control. The system maintains focus on moving targets using smart tracking algorithms. Tracking reduces operator workload during surveillance.
Q3: When does the camera use white light instead of IR?
A: Smart dual light technology switches between IR and white light based on conditions. White light activates for full-colour night vision when needed. IR provides discreet monitoring without visible light.
Q4: What is the difference between overview and detail specifications?
A: Overview specifications apply to the panoramic camera with 2.8mm lens and 30m IR range. Detail specifications apply to the PTZ camera with 5-125mm zoom lens and 100m IR range. Each camera has independent capabilities.
Q5: Does the camera include mounting hardware?
A: Yes. The PFB305W wall mount bracket comes included. This bracket supports wall installation without requiring separate mounting hardware purchases.
