2021: Production of models iDS-2CD7A45G0-IZHS and iDS-2CD7A45G0-IZHSY

On December 8, 2021, Hikvision announced that it had updated the product line of IP cameras of the DeepinView 7 series - the lineup was supplemented by two long-focus cameras with optical zoom to monitor vast areas and remote objects. Models of iDS-2CD7A45G0-IZHS and iDS-2CD7A45G0-IZHSY are suitable for building a security system in projects for airports and other transport infrastructure facilities, in industrial industries (including coastal and maritime facilities), urban squares, stadiums, etc.

Detailing Deleted Objects

A review of large-scale scenes is possible thanks to a motorized variofocal lens with a focal length of 4.7-118 mm. The 25-fold optical zoom provides a high level of detail for remote objects, and the built-in gyroscope, together with the electronic image stabilization (EIS) function, provides image stabilization using the zoom, without a characteristic "jitter." For efficient operation of the system at night time or in conditions of low illumination intellectual , IR lighting with a range of up to 200 meters is provided in the cameras - special smart technology helps to equalize the brightness of the frame lighting, especially when the object is close. Hikvision long-focus cameras also optimize the composition, video monitoring systems replacing conventional devices and reducing the number of equipment in the territory. This provides additional savings not only in the purchase of security devices, but also in their continued maintenance and operation.

Working in difficult weather conditions and aggressive environments

The long-focus cameras of the Hikvision DeepinView 7 series have a wide temperature mode for operation (from -50 to + 60 ° C), which allows you to use devices in different regions and different weather conditions. Models with the H index in the name are equipped with built-in heaters (up to three pieces) that protect the lens from snow/ice and help to ensure high clarity of parts in difficult monitoring conditions. Heaters also maintain comfortable conditions for the operation of microcircuits, array and other important components of the chamber at low temperatures.

Models with an additional index Y in the name have a special anti-corrosion coating that protects the body and internal filling of the chambers from exposure to high humidity, acid and other aggressive media. Hikvision anti-corrosion cameras are internationally certified according to the NEMA 4X standard, and C5-M steel is used to manufacture the case of protected cameras.

Algorithm Deep Learning

The intelligent video analytics on board the presented Hikvision cameras are built on the basis of deep learning algorithms, which provide high accuracy of alarms and notifications. Among the basic functions are detecting and capturing faces in a frame (up to 60 images at a time), comparing images with a loaded database, capturing a human figure, vehicles. Deep Learning algorithms allow you to analyze up to 7 characteristic features of the face (at the same time, face rotation or slope is allowed), up to 13 features of the figure and up to 2 features of the vehicle.

To protect the perimeter, an intelligent classification of objects (person/transport/other) is used, on the basis of which the security system filters alarms and eliminates false positives (for example, when moving small animals, natural phenomena, etc.). Smart functions are also available: detecting line intersection, intrusion into the area, leaving the area, moving the object, changing the scene, defocusing the frame.

2020: Hikvision DeepinView Intelligent Camera Series 7 for Multi-Purpose Scenarios

On July 9, 2020, it became known that Hikvision it released a 7 series of DeepinView cameras with an expanded set of intelligent functions. One DeepinView 7 series camera combines various algorithms for multi-purpose scenarios. You can perform multiple tasks at once, such as facial recognition, visitor counting, personal protective equipment detection, queuing timeouts, and more. The presented series of cameras DeepinView can be widely used in industries such as industry, retail, trade public safety, business, construction etc.

When developing series 7, our engineers took into account three main requests from customers: the presence of intelligent functions, high-quality image, ease of use. Together, this significantly increases the efficiency of the security system, allows you to optimize business processes, reduce the burden on security personnel and reduce the cost of additional personnel, - says Ray Zhang, product manager at Hikvision

In the business sector, advanced intelligent algorithms provide not only accurate facial recognition based on the base loaded into the system (for example, enterprise employees), but also analysis of the main characteristics of the person (for example, gender, age, emotion) - this function is especially useful for working with customers in the retail or services sector. System settings also allow you to count individual groups of people taking into account the list of exceptions - that is, the camera will take into account the number of customers, while excluding store employees when they come into view of the device.

Also, repeated passes of customers in a short period of time will not be taken into account - when the buyer entered the store, went out to call, and then returned again. Another example of the mining algorithm is the function of analyzing so-called attributes (gender, age, facial expression). For example, if the system detects that buyers with children visit the outlet often, then this may be a signal to the manager to increase the number of children's goods to increase turnover. You can also analyze other attributes - the presence of glasses, bags, bicycles, the color of clothes, etc. - says Ray Zhang, product manager at Hikvision

An additional possibility for trading objects is the queue management function. The camera helps optimize cash zones and improve customer service. When the number of people or waiting time in the queue exceeds a specified threshold, the camera sends an alarm to the control panel or directly to the administrator of the outlet to take the necessary measures (open additional cash desks, find out the reason for the long wait, etc.).

To ensure industrial safety and compliance with labor protection requirements, the DeepinView chambers have the function of detecting a protective helmet on the head of a person. The function can be used in scenarios such as construction, extractive facilities, processing plants, energy facilities, etc. If there is no helmet in the monitoring point, an alarm will be triggered, which will trigger an audio or voice warning. When integrating the camera with the access control system, an employee who does not have a protective helmet will not be able to enter the danger zone.

To protect the perimeter of the camera, the DeepinView 7 series uses intelligent video analysis algorithms that reduce the number of false alarms, as well as configure alarms using target classification. You can set the alarm only on people or only on vehicles that come into view of the camera. Another option is to set the exception so that the camera reacts, for example, only to cars. The optional Auto Tracking feature is for low activity scenarios. The camera will respond only to moving objects, focusing on a specific target, thereby increasing the efficiency of the security system and saving space in the vault.

Key features of DeepinView 7 series cameras

Devices form a large amount of metadata based on ISAPI, which allows third-party platforms to efficiently and quickly work with information, extract relevant images for additional analysis. The camera supports multithreaded data transmission - 5 preset and 5 user threads. Each of them supports the modern H.265 compression codec to reduce the load on the data network and save storage space. Multiple threads are also useful for integrating them with different applications.

The network security of the device is provided by several tools at once - software and hardware, which provide protection against unauthorized access to the device through a network connection or physical connection, recording all operations with data, secure connection with servers, etc. The developers paid special attention to protection from external impact - the camera is equipped with a vibration sensor (for example, from an impact on the camera body), when triggered by which an alarm signal will be triggered on the operator's console.
