Hikvision iDS-7208HQHI-K1/4S is an 8-channel CCTV DVR capable of recording surveillance video provided in HD-TVI, AHD, HD-CVI, CVBS and IP standards. The maximum recording resolution is 1080p@15fps, however channels 1 and 2 can support 3MP@15fps. Below 720p, the maximum frame rate is 25 fps. In the 1080 Lite mode, the DVR can cooperate with cameras with image resolution up to 4 MP and record their video with resolution of 1280 x 1440 pixels (in the case of HD-CVI system, the maximum resolution of the connected cameras is 2 MP). Additionally, after switching on Enhanced IP Mode (it disables the video analytics) the DVR can support up to four IP cameras. After switching off the analog channels completely, the DVR can support up to 12 IP cameras.

The iDS-7208HQHI-K1/4S DVR uses AcuSense technology based on Deep Learning algorithms. In traditional monitoring systems, video analytics and object detection is based on changes in pixels. This approach is the source of a significant amount of false alarms caused, for example, by tree movement, rainfall or changes in lighting. AcuSence technology and deep learning algorithms introduce a new approach in monitoring systems, focused on efficient detection of threatening events with minimizing the number of false alarms.

AcuSence technology enables easy finding of people and vehicles in recordings
with ignoring alarms that do not meet the criteria

The DVR can perform the analysis in 4 channels. The function of detecting the target (person, vehicle) is active in the case of virtual line crossing and perimeter breaches (intrusion detection). The AcuSence technology enables easy finding of people and vehicles in recordings with ignoring alarms that do not meet the criteria.

The DVR can record one or two video streams (primary and/or secondary) from each channel. The video can be compressed with the use H.265 method. Compared with the predecessor (H.264), H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or extended data retention time. H.265+ can further minimize the streams in typical video surveillance scenarios.

By activating the Enhanced IP mode, the number of supported IP channels increases. This is done at the expense of switching off the intelligent processing of events in analog channels and limiting the resolution of HDMI/VGA video outputs up to 1080p. The Enhanced IP mode can be activated only with direct access to the DVR's menu.

The recording can be performed in different modes: continuous, motion detection (with pre- and post-event recording), alarm (with pre- and post-event recording), or continuous recording with special parameters in the case of specific events. Each channel can be configured individually in this aspect. It is possible to increase the frame and bit rates, independently of the continuous recording settings. After the occurrence of an event (motion detection, camera tampering etc), the NVR automatically switches to the event-recording mode (usually with higher parameters). During the rest of the time the recording is carried out in the continuous mode. The increased parameters just before and after the event allow to play back every second of the period with high detail and smoothness, while the recordings between events may have a much lower performance, taking significantly less space on the storage media.

Each channel has the possibility of independent settings for intelligent image analysis. The image analysis includes detection of virtual boundary line trespass (including direction), and detection of intrusion to an area of a square shape. The image quality diagnostic function can e.g. send email or alarm message on a worsened focus, excessive brightness or discoloration.

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. Oner 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.

Hik-Connect is also the name of network service intended for Hikvison devices. The service is based on data processing in the cloud and integrates the following functions:

Main window of SADP application

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.
