DS-2CD2421G0-IW(2.8mm)(W)

Hikvision DS-2CD2421G0-IW is a cube-shaped camera designed for indoor use. It boasts a 10m long-range IR LED illuminator, PIR detector, 2.8mm fixed lens, H.265+ encoding and the ability to save video material on a microSD card (up to 256GB). The camera has the ability to connect wirelessly using the Wi-Fi 802.11 b/g/n protocol or via the LAN port. Although a wireless connection is possible, it is not recommended in professional monitoring systems that require image recording due to the possibility of interference and the influence of distance. It can be powered both by a 12V DC power supply and by the PoE 802.3af standard.

Function ANR (Automatic Network Replenishment)

An interesting function used in selected products for Hikvision network monitoring is the ANR (Automatic Network Replenishment) function. This service guarantees the continuity of recordings in the event of a failure, disconnection or loss of the connection between the camera and the recorder. The system works on the principle of automatic detection of a network problem and a safe recording of recordings on the microSD card placed inside the camera. After the failure cessation, the recording is automatically synchronized and in the case of deficiencies the recorder will download the missing fragments directly from the camera.

Compression

H.265+ is a video recording coding system, which is an extension of the technology used in H.265 / HEVC (High Efficiency Video Coding). The H.265+ system is the latest installment of codecs used in monitoring, which is based on an intelligent algorithm developed by Hikvision. Signal coding in the H.265 system is an amazing technology that allows you to optimize the basic camera functions and allows better use of the network bandwidth, significantly reduces interference and guarantees a long archiving time of recording without harming the image quality. Field tests show that the H.265+ compression reduces the required level of high -resolution image transmission speed by about 67% compared to H.265, thus reducing the required band width and mass storage capacity / HDD disk. Reduction of the number of bits means a reduction in costs for consumers, as well as increasing the efficiency, stability and reliability of all equipment in a given supervision system. The use of the H.265+ codec brings the most spectacular performance in images where the background remains unchanged and rarely changes; in the case of objects moving on a stagnant stage and with 24 -hour supervision.

Camera with PoE technology

Power Over Ethernet (Poe) is a solution developed for conducting quick and uncomplicated installation of network devices and comfortable equipment operation and easy installation modernization. Thanks to PoE support in the 802.3af standard, connecting an IP camera will be real using the popular UTP computer pair. Saving the total number of cables necessary to start the device improves the monitoring system and allows the camera to locate away from traditional power sources.

Wi-Fi

The HIKVISION DS-2CD2421G0-IW (W) camera has been additionally enriched with the ability to transmit wireless data. Thanks to the built-in Wi-Fi interface (802.11 b/g/n), it provides the possibility of carrying out wireless communication between the camera and the router or recorder, at a distance of up to 50 m. Wireless connectivity due to the possibility of interference and the impact of distance is not recommended for professional systems monitoring with image record, but using a camera for sporadic preview or video conference.

Smooth streaming

Smooth streaming offers solutions to improve video quality in various network conditions. For example, in the case of a poor network state, adapting to the detected network status in real time, the speed of streaming and the resolutions are automatically adapted to avoid blurring the image and lower delay in the live preview.

VCA

Video Content Analytics technology (video content analysis) is no longer available only in security systems targeted at corporations. Small and medium -sized companies can also enjoy it thanks to the Easyip solution. The staff receives Smart Search tool (intelligent search) to the hands, which can be used in combination with alarm events and detection of events based on VCA, as well as the Smart Playback function (intelligent playback), which allows you to see the registered moment of crossing the line or invading, as well The faces of the perpetrators. The possibilities of releasing alarm and event analysis have been extended to detect the removal of the object and leaving the luggage unattended.

DWDR

DWDR (Digital Wide Dynamic Range) is an advanced technology that allows you to clearly observe complex scenes in all planes of the image.

3DNR

DNR (Digital Noise Reduction) is an electronic system that reduces image noise by dynamically adjusting to different conditions in real time.

Region of Interest (RoI)

Region of Interest (RoI) is a smart codec that optimizes the quality of the most important parts of the image while reducing the quality of less important areas. This allows for more efficient use of signal processing power, reducing network bandwidth requirements and better identifying the most critical points.

EXIR - diodes LED

Unlike standard radiators with round LEDs, EXIR radiators produce a rectangular luminous flux. As a result, they perfectly and evenly cover the entire observation plan, both the central points of the scene and the corners. In traditional technology, usually the center of the plan was overexposed, while the corners of the image were underexposed.

Privacy masks

Privacy masks are a feature that allows you to customize the surveillance system to specific areas.

Fixed focus Lens, IR LED, bracket

The camera is equipped with a 2.8 mm lens with viewing angles: 113 ° (horizontally), 59 ° (vertically) and 135 ° (diagonally). The IR LED radiator ensures visibility at a distance of 10m at night, and the dedicated handle allows for a simple suspended installation or on a flat surface.

Comparison of focal length lenses

The camera is equipped with a 5.9 ~ 147.5 mm lens with an optical approximately 25x and 65 ° ~ 3.8 ° viewing angle.

Support for microSD cards, built-in speaker and microphone

The camera allows you to record an image on memory cards with a maximum capacity of 256GB. The built -in speaker and microphone allow two -way audio communication and effective sound messages.

Solid camera case, bracket included

The Case has tightness at the IP66 level.

Case IP66, IK10

The Case shows tightness at IP66 level and IK10 mechanical resistance.

BLC

BLC - (Backlight Compensation) - a function that allows you to maintain the readability and detail of objects occurring both in the first and second plan of the observed scene. The background lighting compensation system regulates the brightness level of all fragments of the image.
