Hikvision TandemVu 8C Series 4MP 25X DarkFighter Network Speed Dome Camera

Hikvision TandemVu 8C Series 4MP 25× DarkFighter Network Speed Dome Camera The Hikvision DS-2SF8C425MXG1-ELW/14(F1) is a dual-channel TandemVu network camera designed to monitor a broad scene while capturing detailed close-up views. Its 4 MP fixed bullet channel maintains an overview of the monitored area, while the separate 4 MP PTZ channel provides 25× optical zoom, responsive movement and intelligent target tracking. DarkFighter 2.0 technology, long-range infrared illumination and deep-learning analytics support effective monitoring across demanding outdoor environments. Wide-Area Awareness and Detailed PTZ Coverage The TandemVu design combines two independently capable imaging channels in one housing. The fixed 4 mm bullet channel provides an 89° horizontal field of view, helping operators retain awareness of the wider scene, while the PTZ channel can be directed towards activity that requires closer examination. A 5.9–147.5 mm motorised lens gives the PTZ channel 25× optical zoom and 16× digital zoom. With 300 presets, eight patrols and four programmable pattern scans, the camera can be configured to monitor important locations and repeat defined surveillance routes. DarkFighter 2.0 Low-Light Imaging Both channels use 1/1.8-inch progressive scan CMOS sensors and support colour imaging at illumination levels as low as 0.0005 lux under the specified test conditions. The fixed bullet channel includes white-light illumination up to 30 metres, while the PTZ channel provides infrared illumination up to 300 metres for long-range night monitoring. The bullet channel supports 120 dB wide dynamic range, while the PTZ channel provides 150 dB WDR. Electronic image stabilisation, digital defog, highlight compensation and 3D digital noise reduction help maintain usable images in difficult lighting and environmental conditions. Deep-Learning Analytics and Target Tracking Deep-learning functions support perimeter protection, face capture, face comparison, road-traffic detection and simultaneous detection of people, faces and vehicles. Auto-tracking 3.0 enables the PTZ channel to follow selected targets, while linked tracking allows activity detected within the fixed view to support closer PTZ observation. Event responses can include recording, notifications, alarm-output activation, an audible warning, a flashing white light and PTZ actions. Analytics should be configured for the installation environment and used in accordance with applicable privacy and data-protection requirements. Built for Demanding Outdoor Installations The ADC12 metal housing carries an IP67 weather-resistance rating and an IK10 impact-resistance rating, excluding the glass window. It also provides TVS 6000 V lightning protection, surge protection and voltage-transient protection. An integrated wiper, demist function and operating range from -40°C to 70°C help support dependable operation in exposed locations. Key Features: Dual 4 MP channels capture the wider scene and detailed PTZ views at the same time. 25× optical and 16× digital zoom provide close-up observation across expansive areas. DarkFighter 2.0 technology supports detailed imaging in very low light. Up to 30 m white-light and 300 m infrared illumination extend night-time coverage. Deep-learning analytics support perimeter protection, face, person and vehicle detection. Auto-tracking 3.0 and linked tracking help operators follow activity across the monitored area. IP67 and IK10 protection, an integrated wiper and wide operating-temperature range support outdoor deployment.
