The Hikvision DS-2CD7A46G0-IZS camera is dedicated for professional IP CCTV systems. The compact camera has been equipped with high quality 4 MP 1/1.8" CMOS sensor providing good video coverage even in very low-light conditions. Along with IR illuminator with range up to 50 m, the camera can also operate in complete darkness. The built-in 2.8–12 mm Motozoom lens allows for remote change of the viewing angle within 104°– 29° range. The lens focuses automatically when the focal length is changed. The IP67-rated housing of the camera protects the electronics against adverse weather conditions. The camera can be powered conventionally with a 12 VDC source or with the use of PoE option (802.3at).
The image analysis performed by the camera is based on deep learning algorithms. They simulate the structure of the human brain. Like in the brain, the process of learning builds connections between artificial neurons (programs) and creates a multi-layered artificial neural network. The algorithms independently analyze the model photos and recordings, creating the right connections. In this way, they create so-called layers responsible for detecting specific features. The more layers the algorithms have, the more accurate the analysis.
Multilayer networks can collect information and perform appropriate actions, primarily automatic extraction and representation of features (patterns) present in the data that teach the network, resulting in recognizing faces, vehicle makes, animal species, or events such as fall of a person.
Available functions based on deep machine learning:
  • face detection,
  • queue monitoring,
  • line crossing,
  • intrusion, object leaving, object taking.

H.265+/H.265 video compression
The camera implements several video compression methods, H.265+, H.265, H.264+, H.264, MJPEG. Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or into extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios. With the advanced video compression algorithms, the camera can be used in IP CCTV systems based on modern NVRs implementing H.265 standard (the DS-76/77/96NI-I/K series supports H.265+, H.265, H.264+, H.264). Of course, the camera can also operate with older models supporting H.264 (the DS-76/77NI-E series supports H.264+, H.264).

The built-in powerful IR illuminator has a range of up to 30 m. The illuminator based on the newest Exir 2.0 light-emitting technology has ca. 30% higher efficiency compared with traditional IR LED arrays. Additionally, the IR light in the form of a rectangle fits the camera's field of view. This further improves the efficiency of the lighting and eliminates the excessive light intensity in the central part of the scene, typical for majority of IR illuminators. Exir 2.0 illuminators ensure much better luminance uniformity, including corners of the scene, at the same time reducing light pollution in the surrounding environment.
Continuity of recording thanks to ANR function
With the support of ANR (Automatic Network Replenishment), each the IP camera equipped with a memory card can record video in the absence of network connection. After the restoration of the network connection, the recordings are automatically synchronized with those recorded on the NVR. This ensures continuous coverage of events, even in the case of communication problems between the camera and NVR.
Convenient client applications
The iVMS 4200 client software enables users of HIKVISION devices to manage them in IP networks. The software allows for configuration and management of NVRs/DVRs, IP and analog cameras (in hybrid systems). The iVMS 4200 utility can remotely manage up to 256 devices, with the use of up to 4 monitors. One monitor can display up images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifying, two-way audio transmission, creating multi-level e-maps.
Hik-Connect is a mobile application, intended for smartphones running Android or iOS operating systems. It can be used for remote live viewing of images from DVRs, NVRs, network cameras via Wi-Fi, 2G or 3G networks, and for playing back recorded video files. The application connects with the devices by IP addresses and/or through the P2P cloud.
Working in the cloud
Hik-Connect is also a network service for Hikvison devices. The service is based on data processing in the cloud and integrates the following functions:

  • Remote access through the cloud - it allows access to the device without having an external IP address and when simplicity is the most important thing. Only the basic configuration of the network is required. The application on a PC or smartphone connects with the device via P2P cloud service,
  • DDNS server - DDNS assigns a fixed domain name to dynamically changing IP addresses (Dynamic DNS). This feature is useful when the ISP does not provide users with a fixed IP address. The condition for using DDNS is having a public IP address and providing access from the external network to the appropriate ports of the NVR (server and http, by default 8000 and 80). The connection is possible via a web browser, client application on a PC and on smartphones.
Protection against vandalism
The degree of protection (IK rating) provided by enclosures for electrical equipment against external mechanical impacts is defined in the EN 62262 standard. The EN 62262:2003 standard specifies the conditions of the testing procedure.
The camera has IK10 rating.

LAN tool for organizing Hikvision IP CCTV systems
SADP (Search Active Device Protocol) is a free and simple to use utility for searching Hikvision IP cameras and Hikvision DVRs/NVRs in the local network. The network device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords. Detailed information on the software and its use is contained in the SADP application - LAN tool for organizing CCTV systems based on Hikvision devices article.
