Camera highlights

The DS-2CD2T46G2-2I -4I tube camera is based on the AcuSense technology, which, using Deep Learning algorithms, enables object classification (vehicle / human), and thus filtering false alarms from VCA events, e.g. perimeter protection. The camera is equipped with a modern 1/3 "4Mpx Progressive Scan CMOS image sensor , which allows you to record video recordings with a maximum speed of 25/30 fps in a resolution of 2688 × 1520 (4Mpx) . The device is equipped with a very durable housing, which is characterized by a high degree of resistance to unfavorable weather conditions (IP67) H.265 compression systemthe signal transmitted by the camera takes up less space on the recording medium (e.g. HDD or microSD card), which translates into effective protection and longer data storage time. It is worth noting that despite the compression, the transmitted information retains its detail and high quality. The camera is equipped with a 2.8mm fixed lens and an intelligent SMART infrared heater. Both of these systems provide a clear and legible image adapted to the prevailing lighting conditions. The -2I model allows for additional lighting at a distance of 60m , and the -4I model at 80m. Thanks to PoE technologyand numerous complementary products, the installation of the camera is quick and uncomplicated.

Intuitive menu navigation

The management and operation of the Hikvision IP megapixel camera is carried out using a clear and transparent management program from the level of a web browser. Using the intuitive menu, it is possible not only to test the cameras and view the recorded image on a current basis, but also to set image and stream parameters as well as to accurately determine the dates and time intervals in which the camera is to operate. Access application versatilityIt also guarantees immediate notification of the user about the possible duplication of the camera's IP address or loss of connection with the device, which significantly secures the proper operation of the cameras and maintains the effectiveness of the monitoring system. The stability of the camera operation according to individual user parameters is also ensured by the option of making a backup of the settings, and the preventive automatic restart function of the camera secures the daily recording efficiency.

AI functions

Innovative AcuSense technology based on self-learning artificial intelligence algorithms that can filter out 98% of false alarms. The camera, thanks to the classification of objects, is able to determine whether a human or vehicle has been detected and can filter out events caused by animals, weather conditions, light, and even falling leaves. Classifying the device as a false alarm, it improves the recipient's work.
AI functions that handle the event data:

Perimeter functions / Perimeter protection:

Monitoring of areas requiring protection and information in the event of an intrusion. When entering the designated area or crossing the designated line, the classification of the object begins, if the system detects that it is a person or a vehicle, an alarm is triggered, otherwise it is ignored.

Face recognition

Each face model is compared with the photos stored in the database for identification purposes, which can be used to authorize entry to rooms with restricted access. Authentication is successful when the face is recognized.

Motion detection (human / vehicle)

Motion detection based on object recognition- This technology has an algorithm that first classifies objects (human / vehicle) and the detection takes place in the second stage, which allows for proper alarming regardless of the type of platform that will receive the already developed alarm information, be it IVMS 4200, HikCentral or other Hikvision software. Thanks to the motion detection 2.0 function, we can count on high accuracy and efficiency of alarming based on not only line intersection, intrusion into a zone, but also during the detection of standard motion detection, which allows for easier alarm configuration. It is not necessary to draw lines, determine the minimum and maximum size of objects, etc. It is enough to draw a standard motion detection grid (activity mask) and define what type of objects are to be analyzed by the device (vehicle)

Image correction functions

• 3D DNR -DNR is a system that allows you to electronically minimize the noise in an image. It is based on dynamic real-time regulation, constantly reacting to changing conditions.

• WDR 120dB- (Wide Dynamic Range) - The wide dynamic range of the image is a system with which it is possible to observe a complex scene while maintaining the transparency of all image planes.

RoI (Region of interest)

It is an intelligent codec that allows you to improve the quality of selected image fragments and to reduce the quality of other fragments. This has a positive effect on the use of the computing power of the signal processor, reduces the requirements for network bandwidth and improves the identification of only the most sensitive points.

Privacy masks

It is a function that allows individual adjustment of the way the observation system operates to the spatial specificity and safety requirements of a specific installation site. Thanks to the privacy mask system, it is possible to freely determine the fragments of the image that will be excluded from the video surveillance.

Signal transmission and power supply with one cable - PoE

Power over Ethernet is a solution designed for quick and easy installation of network devices, comfortable operation of the equipment and easy modernization of the installation. Thanks to PoE support in the 802.3af standard, it will be possible to connect an IP camera using the popular UTP twisted-pair cable. The saving of the total number of cables necessary to start the device improves the monitoring system and allows the location of the camera away from traditional mains power sources.

Innovative codec - Hikvision H.265+

H.265 + is a video coding system that is an extension of the technology used in H.265 / HEVC (High Efficiency Video Coding). The H.265 + system is the latest version of the codecs used in monitoring, which is based on an intelligent algorithm developed by the Hikvision company. H.265 signal encoding is a remarkable technology that allows you to optimize the basic functions of the camera and enables better use of network bandwidth, significantly reduces interference and guarantees long archiving times without compromising image quality. Field tests show that H.265 + compression reduces the required level of high definition video bitrate by approximately 67% compared to H.265, thus reducing the required bandwidth and storage / HDD capacity. Reducing the number of bits means lowering costs for consumers as well as increasing the efficiency, stability and reliability of all equipment in a given surveillance system. The use of the H.265+ codec brings the most spectacular results in images where the background remains unchanged and rarely changes; in the case of objects moving on a stagnant scene and with 24-hour surveillance.

Direct access to the camera on the Hik-Connect platform

The presented device allows you to directly establish a connection with a computer or any mobile device via a cloud-based system. The advantage of this solution is the ability to gain remote access to both the camera, recorder, recordings, and a number of useful functionalities. Device registration is very simple via a web browser or via QR codes. It is worth emphasizing that the P2P Hikvision service does not require additional port forwarding from the user. The method of communication in the Peer to Peer technique significantly facilitates access to the monitoring system, which is a solution especially recommended when using LTE mobile wireless Internet.

Software iVMS-4200 & iVMS-4500

The free iVMS 4200 client software is available in the set with the camera. The program is used for image preview, surveillance and camera configuration. The application is highly functional and allows you to create a professional workplace for the system supervisor and other users. The CMS client can cooperate with up to 256 recorders and in addition to displaying live image or playing recordings, it enables multi-monitor operation, e-map support, display of alarm messages, two-way audio transmission or advanced search for individual events. In the case of more complex systems, a useful function of the application is the ability to create accounts with different levels of authorization. The program for a personal computer is complemented by the iVMS-4500 mobile application, which is available for Android, iOS or Windows Phone. 

SADP configuration application

The SADP application (Search Active Devices Protocol) is a user-friendly software tool for online device search that does not require installation. It searches for active online devices on your subnet and displays information about those devices. With this software you can also modify the basic network parameters of these devices.
