Overview:

4 MP Hikvision DarkFighter Fixed Bullet Network Camera
The Hikvision DS-2CD2T46G2H-2I/4I is a 4 MP fixed bullet network camera designed to deliver clear, reliable surveillance in a wide range of indoor and outdoor environments. Powered by Hikvision DarkFighter technology, it provides strong low-light performance while maintaining detailed video quality. The 120 dB true WDR technology also helps produce clearer images in scenes with strong backlighting, making it suitable for entrances, driveways, parking areas, commercial properties and other security-sensitive locations.

Description:

This Hikvision 4 MP bullet camera combines high-resolution imaging, intelligent target classification and efficient video compression in a durable outdoor-ready design. Its 2688 x 1520 resolution provides detailed footage, while the 2.8 mm fixed lens offers a broad viewing perspective for monitoring larger areas.

DarkFighter technology improves image quality in low-light conditions, helping the camera capture useful surveillance footage when lighting is limited. With up to 60 m of infrared illumination, the camera can continue monitoring areas after dark without requiring additional lighting.

The camera also uses deep learning technology to help distinguish between human and vehicle targets, reducing unwanted detection events and making security monitoring more practical. Perimeter protection and face capture capabilities provide additional options for intelligent surveillance applications.

The camera supports H.265, H.264, H.265+ and H.264+ video compression, helping reduce bandwidth and storage requirements while maintaining useful image quality. A built-in memory card slot provides local storage options, while the RJ45 Ethernet connection supports network connectivity for integration into compatible surveillance systems.

Features:

Image Quality and Low-Light Monitoring
The 4 MP image sensor delivers a maximum resolution of 2688 x 1520 for detailed surveillance footage. DarkFighter technology is designed to improve performance in challenging lighting conditions, while 120 dB WDR helps balance bright and dark areas within the same scene.

Additional image processing includes:

• 120 dB true WDR for challenging backlight conditions
• 3D digital noise reduction for cleaner images
• BLC for improved visibility in backlit scenes
• HLC to help manage strong light sources
• Infrared illumination up to 60 m for night surveillance
• 1 fixed region of interest for prioritising important areas

Intelligent Security Monitoring
The camera uses deep learning-based technology to classify human and vehicle targets. This can help improve detection accuracy and make security alerts more relevant. Face capture and perimeter protection functions provide further support for security applications where intelligent event detection is required.

Up to 6 channels can be viewed simultaneously, making the camera suitable for integration into network video surveillance environments where multiple video feeds need to be monitored.

Network and Storage
A 10M/100M self-adaptive RJ45 Ethernet port provides the network connection for video transmission, configuration and integration with compatible surveillance equipment. The built-in memory card slot also allows supported local recording options.

Video compression support includes:

• H.265 and H.265+ for efficient bandwidth and storage usage
• H.264 and H.264+ for compatibility with a range of surveillance systems

Outdoor-Ready Bullet Design
The fixed bullet housing is designed for outdoor surveillance applications and carries an IP67 rating for resistance against dust and water. This makes the camera suitable for installations such as building exteriors, entrances, perimeter areas, warehouses, parking facilities and other exposed locations.
