Dahua 8MP X-Spans DH-SDT8C842-8P-FA-APV-0280 Panoramic PTZ Camera with 42x Zoom, 300m IR & 30m White Light

Product SKU: DH-SDT8C842-8P-FA-APV-0280

Product Overview

The Dahua DH-SDT8C842-8P-FA-APV-0280 is an 8MP X-Spans panoramic PTZ camera designed for large commercial, industrial and infrastructure sites that need continuous wide-area awareness and long-range detailed investigation from one unit. Its panoramic channel combines two 4MP sensors to produce an approximately 200° horizontal overview, while the separate 8MP detail channel uses a 5.5–231mm motorised lens with 42× optical zoom. This allows operators to keep watching the broader scene while the PTZ channel follows or inspects a distant person, vehicle, gate or boundary. The detailed channel provides infrared illumination up to 300 metres, while the panoramic channel adds white-light illumination up to 30 metres. Auto Tracking 3.0, perimeter protection, video metadata, face recognition, AcuPick and sound-and-light deterrence support professional monitoring and investigation. PoE++, IP67 protection, a built-in wiper and local microSD storage suit demanding outdoor deployments.

Key Capabilities

Best For

• Large Car Parks: Maintains a broad overview while the detail channel inspects vehicle entrances, parking rows or distant activity.
• Warehouses and Logistics Yards: Supports monitoring across loading docks, access roads, storage areas and building perimeters.
• Commercial Campuses: Covers several outdoor zones from one elevated position using presets, tours and tracking.
• Industrial and Infrastructure Sites: Long-range zoom, metadata and alarm interfaces suit complex monitored environments.
• Restricted Perimeters: Combines classification, linkage tracking and sound-and-light warnings around controlled boundaries.

Why Choose the DH-SDT8C842-8P-FA-APV-0280

The DH-SDT8C842-8P-FA-APV-0280 addresses a common limitation of conventional PTZ cameras: losing the original overview when the camera turns or zooms towards another target. Its panoramic channel continues covering the wider area while the 42× detail channel performs closer inspection or automatic tracking. This makes it better suited to complex sites than a standalone PTZ or several basic fixed cameras where operators need both context and long-range detail. Face recognition, metadata, perimeter analytics, AcuPick and active deterrence provide additional investigation and response options. Available through Security Wholesalers, this model is best considered for professionally designed systems where its weight, PoE++ requirement, analytics and mounting position can be properly accommodated.

Ideal Use Cases

Choosing the Right Model

• Choose this model if: You need a continuous panoramic overview together with a separate 42× tracking and investigation channel.
• Choose a standard PTZ if: Wide-area overview can be provided by separate fixed cameras and a smaller or lighter PTZ is preferred.
• Choose fixed cameras if: Several individual areas must always remain recorded at full detail without PTZ movement.
• Confirm PoE capacity if: The camera will use PoE++, because maximum consumption can reach 58W.
• Confirm backend compatibility if: AcuPick, face recognition or the full metadata workflow is essential to the project.

FAQs

1. How do the panoramic and PTZ channels work together on the DH-SDT8C842-8P-FA-APV-0280?
   The DH-SDT8C842-8P-FA-APV-0280 combines an 8MP panoramic channel with a separate 8MP detail PTZ channel. The panoramic view covers approximately 200° horizontally, helping operators maintain broad awareness while the lower PTZ camera pans, tilts, zooms or tracks a selected target. This arrangement is useful on large sites because the wide overview remains available while detailed investigation is carried out in another direction.
2. How far can the camera see at night?
   The detailed PTZ channel provides infrared illumination up to 300 metres, while the panoramic channel provides white-light illumination up to 30 metres. Infrared supports long-range monochrome viewing, whereas the panoramic white light supports visible illumination and colour detail closer to the camera. Actual usable identification distance depends on zoom position, weather, target size, reflections, mounting height and the available ambient lighting.
3. How powerful is the 42× optical zoom?
   The detail channel uses a 5.5–231mm motorised lens with 42× optical zoom. Its horizontal field of view changes from approximately 61.8° at the wide end to 2.2° at full telephoto, allowing operators to place more image detail on distant gates, vehicles or perimeter activity. Full telephoto provides a very narrow view, so presets and operator training are important when several site areas must be monitored.
4. Can the DH-SDT8C842-8P-FA-APV-0280 automatically track people and vehicles?
   Yes. The camera supports Auto Tracking 3.0, linkage tracking and perimeter analytics with human and vehicle alarm classification. It can respond to events such as tripwire, intrusion, fence climbing, loitering, fast movement and parking. Tracking performance still depends on correct commissioning, target visibility, movement speed and obstructions. The panoramic overview helps retain broader awareness while the detailed PTZ channel follows a selected target.
5. What does the active-deterrence function include?
   The active-deterrence function combines a white-light warning with sound alarms played through the built-in speaker. Flash duration can be set from 5 to 30 seconds, with high, medium or low flash frequency. The camera provides 22 sound alarms and supports importing custom alarm sounds. A separate line-level audio input is available, but no built-in microphone is confirmed, so external audio hardware is required when sound input is needed.
6. Does the camera support face recognition and intelligent target searching?
   Yes. The camera supports face detection, attribute extraction, face databases and comparison against up to 10,000 registered faces. It also supports video metadata for faces, human bodies, motor vehicles and non-motor vehicles. AcuPick uses compatible backend intelligence to locate relevant targets in recorded video. When planning the system through Security Wholesalers, confirm the recorder or management platform, firmware and required face-management workflow before deployment.
7. Can the camera record locally and connect to alarm or audio equipment?
   Yes. The DH-SDT8C842-8P-FA-APV-0280 supports a microSD card up to 512GB, together with FTP and NAS storage. It provides one line-level audio input, one line-level audio output, seven alarm inputs, two alarm outputs and one RS-485 interface. Storage media, external microphones and any connected alarm devices must be selected separately and matched to the camera’s electrical and system requirements.
8. What power and mounting arrangements does this panoramic PTZ require?
   The camera supports 36V DC or PoE++ under IEEE 802.3bt and can consume up to 58W when illumination, warning, heating, analytics and PTZ functions are active. Its net weight is 8.8kg, so it requires a suitable supporting structure and correctly rated mount. The datasheet lists a wall bracket, mount adapter and 36V power adapter as included. Correct sealing, earthing and surge protection remain essential outdoors.
