Product SKU: DS-2SF7C442MXG2-LM-EL-W-Y-26F0
Product Overview
The Hikvision DS-2SF7C442MXG2/LM-ELWY/26(F0) TandemVu PTZ Camera combines a 6MP panoramic bullet channel with a 4MP long-range PTZ channel to capture broad situational awareness and detailed target footage at the same time. The panoramic channel uses an ultra-wide 2.8mm lens with approximately 190° horizontal coverage, while the PTZ channel provides 42× optical zoom through a 6–252mm motorised lens. DarkFighter low-light performance, intelligent perimeter protection, Auto-Tracking 3.0, white light, long-range infrared, a built-in wiper and PoE++ support suit large outdoor sites. The official specification does not describe a thermal channel or 26mm thermal lens; “/26” is part of the product variant designation.
Key Capabilities
TandemVu Dual-Channel Coverage
Maintains a panoramic overview through the fixed bullet channel while the PTZ channel zooms, tracks and inspects distant activity.
42× Optical Zoom
The 6–252mm motorised PTZ lens moves from broad site coverage to tightly framed long-distance monitoring.
Ultra-Wide 6MP Panoramic Channel
The fixed bullet channel records at up to 3680 × 1656 and captures approximately 190° horizontal coverage.
Long-Range Night Monitoring
The panoramic channel provides up to 60m infrared and 40m white light, while the PTZ channel provides infrared illumination up to 400m.
Large-Scale AI Perimeter Protection
A dedicated large AI model classifies human and vehicle targets for line crossing, intrusion and region-based events.
Auto-Tracking 3.0
Supports manual tracking, automatic tracking, tracking takeover and linked target capture across wide areas.
Best For
- Industrial Perimeters: Combines persistent panoramic coverage with detailed PTZ tracking across fences, yards and restricted zones.
- Ports and Logistics Facilities: Wide coverage and 42× zoom suit container yards, loading areas, vehicle routes and distant activity.
- Critical Infrastructure: Suitable for utilities, substations, transport hubs and high-security campuses.

Why Choose the DS-2SF7C442MXG2/LM-ELWY/26(F0)
Choose the Hikvision DS-2SF7C442MXG2/LM-ELWY/26(F0) when a site needs continuous panoramic awareness without losing the ability to zoom in and track an event. The TandemVu design keeps the fixed overview visible while the PTZ channel follows a person or vehicle, reducing the risk of losing context during active tracking. Its dedicated large-scale AI model improves perimeter filtering, while Auto-Tracking 3.0, multi-target detection, scene-aware object detection and long-range infrared support complex large-site surveillance. Security Wholesalers supplies this specialised camera for professionally designed perimeter, transport and critical-infrastructure systems.

No. The official specification lists a 6MP optical panoramic channel and a 4MP optical PTZ channel. It does not include a thermal detector, temperature measurement or a 26mm thermal lens. - What does TandemVu mean?
TandemVu combines a fixed panoramic camera with a motorised PTZ camera in one unit. The panoramic channel keeps the overall scene visible while the PTZ channel zooms in and follows a target. - How much optical zoom does the PTZ channel provide?
The PTZ channel uses a 6–252mm motorised lens with 42× optical zoom and 16× digital zoom. This supports detailed inspection of distant people, vehicles and assets. - How far does the infrared illumination reach?
The PTZ channel provides infrared illumination up to 400m, while the panoramic channel provides up to 60m infrared and 40m white-light illumination. Actual performance varies with weather, zoom position and target reflectivity. - Can the camera automatically track targets?
Yes. The PTZ channel supports Auto-Tracking 3.0, manual tracking, tracking takeover and linked target capture. It can track supported human and vehicle targets after correctly configured events. - What does the large-scale AI model do?
The dedicated perimeter model classifies human and vehicle targets for line crossing, intrusion, region entrance and region exit events. It is designed to reduce false alarms compared with conventional analytics. - What power supply does the camera require?
The camera requires 36V DC or IEEE 802.3bt Type 4 Class 8 PoE with up to 90W available. A conventional PoE or PoE+ port is not sufficient. - What should I check before purchasing this TandemVu camera?
Confirm the mounting structure, required viewing distances, PoE++ or 36V DC power, recorder compatibility, AI feature support, bandwidth, storage and environmental exposure. Security Wholesalers can supply this model for professionally designed large-site Hikvision systems.
