The camera

The DS-2TD2628-7/QA is an IP bispectral camera from Hikvision's HeatPro series that combines the benefits of traditional and thermal imaging surveillance. It has with two image sensors, the first CMOS for visible light with a resolution of ++ +2688 x 1520 px, the second, thermal imaging sensor with a resolution of ++ +256 x 192 px. The camera can create image fusion, i.e. combine a visible image with an infrared image to achieve a quality thermal presentation. The VCA analytics working with the built-in GPU graphics processor and deep learning algorithm allows for effective intruder detection and reduction of false alarms. Temperature measurement and fire detection allow it to be used in more advanced projects. The camera is equipped with a microSD card slot allowing the use of cards up to 256GB. The IP67 rated housing protects the inside electronic components from adverse weather conditions. The camera can be powered conventionally with 12 VDC or through PoE+++ (compliant with the 802.802.3af standard).

The following tables illustrate the detection ranges with the smart function and the ranges of detection, recognition and identification of a person or vehicle. The tables are given for reference only and the ranges may vary depending on the camera model.

The DS-2TD1228-2/QA camera has VCA image analytics operating with a built-in GPU and deep learning algorithm. This combination allows it to be used effectively and minimize false alarms. There are 4 types of analysis available: line crossing, intrusion detection, zone entry and zone exit detection. A maximum of 8 rules can be run at the same time. Temperature measurement is possible in the range of -20°C to +150°C with an accuracy of +/-8°C. There are 3 types of measurement available: point, area, line. A maximum of 21 rules can be set, consisting of 10 points, 10 areas and 1 line. In the case of fire detection, up to 10 points of the fire source can be dynamically detected.

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.

Compression is a very important parameter proving the device advancement. The better the compression, the lower the bandwidth requirement with the same subjective quality. H.265 (HEVC - High Efficiency Video Coding) is currently the most efficient compression method. Compared to its predecessor (H.264), it reduces the data stream and the demand for disk capacity by half. Therefore, hard drives with a halved capacity can be used, or recordings can be stored for twice as long.

A mobile application Hik-Connect is dedicated to operate Hikvision devices using cell phones with the operating system Android or iOS. It can be used to remotely view live video from DVR, NVR, network cameras, video intercoms using Wi-Fi, 2G or 3G networks as well as to view recorded video. Video intercoms can be operated with the application which additionally allows for remote opening of electric doors, receiving notifications and transferring calls from the entrance panel to the phone in the absence of the resident. The application supports connectivity via IP and the P2P cloud. Hik-Connect is also the name of a cloud-based service that allows access to devices in the absence of an external IP address.

Our library provides an overview of applications dedicated for installers and users of monitoring systems based on Hikvision devices.

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, its use and password recovery (par. 8) can be found in the following article: SADP application - LAN tool for organizing CCTV systems based on Hikvision devices.
