Hikvision DS-7324HUHI-K4 is a 24-channel CCTV DVR capable of recording surveillance video provided in HD-TVI, AHD, CVBS and IP standards. The maximum recording resolution is 5 MP @ 12 fps. The DVR can also record video with 4 MP image resolution at 15 fps or 3 MP image resolution at 18 fps. In the case of 1080p / 960x1080 / 720p / VGA / WD1 / 4CIF / CIF resolutions, the maximum frame rate is 25 fps.

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.

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 and VQD (image quality diagnostic function that can e.g. send email or alarm message on a worsened focus, excessive brightness or discoloration). The image analysis includes detection of virtual boundary line trespass (including direction), and detection of intrusion to an area of a square shape. One analog channel allows for running people counting function or thermal mapping.

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 for smartphones running Android or iOS. It can be used for live monitoring and playback of images from DVRs, NVRs, IP cameras via Wi-Fi, 2G or 3G networks. The connectivity can be set with the use of IP addresses or P2P cloud service.

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:

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.
