Bispectral Camera: Hikvision DS-2TD2617B-6/PA(B) (optical+thermal imaging, body temperature measurement, compact/bullet)

Support

Details

The camera is a part of project-based approach of Hikvision.It means that the wholesale price of the camera depends on the characteristics of the proposed project and is subject to negotiation.
DS-2TD2617B-6/PA(B) is a thermographic camera designed for temperature measurements of objects in real time with high accuracy of +/- 0.5°C (+/- 0.3°C using black body calibrator) within the range of 30°C to 45°C. This type of solution is perfect for places where there is a need to test temperatures of a large number of people in a short time, such as at/in airports, schools, hospitals, companies, prisons, shopping malls, stores etc.
DS-2TD2617B-6/PA(B) is also a bispectral Hikvision IP camera that combines the advantages of traditional video monitoring and thermal imaging. The functions are preformed by two image sensors, one of them (visible light) is CMOS with image resolution of 2688 x 1520 px, the second detects far-infrared radiation with resolution of 160 x 120 px. The camera can combine the both images into one fusion image with good quality and a wealth of information. AI-based detection based on the built-in GPU graphics processor allows for high-precision temperature measurements and essentially reduces the number of false alarms. The slot for a microSD card accepts cards up to 128 GB. The IP66 rated housing protects the electronics of the camera against the effects of unfavorable ambient conditions. The camera can be powered conventionally with 12 VDC or with the use of PoE option (802.3af compliant).
NOTE! Current software version is available
Principle of operation and advantages of thermal imaging
A thermal imaging camera is a perfect complement to visual monitoring in the reflected visible light and near-infrared radiation. Analog or IP cameras used in video monitoring enable correct identification and recognition of people during the day and at night with the use of infrared illuminators. A thermal imaging camera does not need any lighting for proper operation. Its operating principle is completely different than in the case of traditional cameras. Any body with a temperature above absolute zero (0 K = -273.15°C) emits infrared radiation. Due to the existing relationship between the temperature and radiation intensity, a thermal imaging camera, receiving the far-infrared radiation, calculates temperature values based on the wavelengths of the radiation. So, a thermal imaging camera can show the temperature distribution on the surface of the examined body and measure the temperature values.

Additional supported technologies
H.265/H.264 video compression
H.265 ensures higher compression ratios while preserving the video quality provided by H.264
The camera implements several video compression methods, such as H.265, H.264, and MJPEG. Compared with its predecessor (H.264), H.265 can reduce the data stream by half, which translates into proportional disk space savings and extended data retention time. Thanks to the availability of several compression methods, the camera can be employed in IP CCTV systems based on modern NVRs using the H.265 standard, as well as older models that support the H.264 method.
Convenient client applications
iVMS-4200 is a client software dedicated for the management of Hikvision systems such as NVRs (IP, TurboHD), video intercoms, access control, decoders, etc. The software makes it easy and convenient to control all the systems, providing a live view from IP cameras, remote playback, remote configuration, alarm event support, two-way audio transmission, e-maps, HDD recording, and many other functions. The app allows to manage up to 256 devices and stream footage from 64 cameras on up to 4 monitors.

Hik-Connect is a mobile application intended for smartphones with the Android and iOS operating systems. It can be used for the remote live viewing of footage from DVRs, NVRs, network cameras via Wi-Fi, 2G, or 3G networks, as well as the playback of recorded video files. The application connects to the devices by IP addresses and/or through the P2P cloud service.

Working in the cloud
Hik-Connect is also a network service for Hikvison devices. The service is based on cloud data processing and integrates the following functions:
  • Remote cloud access - allows access to the device for users without an external IP address or when simplicity is imporant. Only the basic configuration of the network is required. The PC or smartphone app connects with the device via a 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. To be able to use DDNS, it is necessary to have a public IP address and provide 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 or via a PC or a smarphone client application.
Advanced applications for organizing and operating CCTV systems
Various applications intended for the installers and operators/users of video surveillance systems based on Hikvision devices are described in this article.

The main window of the SADP application
SADP (Search Active Device Protocol) is a free, easy-to-use utility designed to search for Hikvision IP cameras and DVRs/NVRs in the local network. The network device search tool can also be used to modify device network parameters, e.g. to change or recover default passwords. Detailed information on the software and its use can be found in the following article: SADP application - LAN tool for organizing CCTV systems based on Hikvision devices.
