The 2-MP fixed cube IR camera, model DS-2CD2421G0-I-F2.8, from Hikvision is a compact and versatile indoor surveillance camera suitable for environments such as homes, offices, and retail spaces. This model is equipped with a 2-megapixel high-resolution sensor that delivers clear and sharp images, recording video at 1920×1080 pixels resolution, ensuring detailed coverage of indoor spaces.
Key features:
- High image quality with 2 MP resolution
- Efficient H.265+ compression technology
- Real-time security with built-in two-way audio
- Human body detection using passive infrared (PIR) sensitive to body heat
- DC power supply
The camera features a 2.8mm fixed lens, providing a wide-angle field of view, ideal for monitoring large areas with a single camera. The lens is equipped with an infrared cut filter (IRCF) and IR LEDs, enabling effective night vision up to 10 meters. This capability ensures continuous surveillance, capturing high-quality video regardless of lighting conditions, making the camera exceptionally reliable for 24/7 operation.
The DS-2CD2421G0-I-F2.8 is equipped with Hikvision’s innovative image processing technologies such as Digital Wide Dynamic Range (DWDR) and 3D Digital Noise Reduction (3D DNR). DWDR helps balance the contrast between bright and dark areas, ensuring visibility of details even in high-contrast or backlit conditions. 3D DNR helps reduce noise in the video stream, particularly in low-light conditions, improving image clarity without increasing bandwidth consumption.
The camera supports H.264 and H.265 compression standards, which help reduce file sizes and save bandwidth while maintaining high-quality video output. This data management efficiency makes it easier to store more footage and reduces strain on network resources, which is crucial in multi-camera systems.
Additionally, the DS-2CD2421G0-I-F2.8 comes with several intelligent detection features such as motion detection, video tamper alarms, and intrusion detection. These features allow the camera to actively alert users to potential events, providing proactive security solutions rather than just passive monitoring.
For added functionality, the camera is equipped with a built-in Wi-Fi module, allowing for flexible installation without the need for cabling, and supports ONVIF (Open Network Video Interface Forum) and RTSP (Real-Time Streaming Protocol) standards. This ensures compatibility with a wide range of third-party network video recorders and surveillance systems, making integration into existing security infrastructure simple and straightforward.
The cube design of the DS-2CD2421G0-I-F2.8 is both discreet and modern, fitting well into various interior decors. It also features audio capabilities like a built-in microphone and speaker, providing two-way audio communication. This can be particularly useful in scenarios where interaction or warnings are required, adding an extra layer of security with the ability to communicate directly through the camera.
