HD-TVI DVR: Hikvision DS-7204HQHI-K1/E(C)(S)(4ch, 2 MP, 15fps, H.265, HDMI, VGA) TURBO HD 4.0

The Hikvision DS-7204HQHI-K1/E(C)(S) is a 4-channel DVR for CCTV systems. It allows for recording in HD-TVI, HD-CVI, AHD, CVBS and IP systems. Video from 1080p and 720p cameras can be recorded at 15 fps. Additionally, 1 channel can record video from 3 MP cameras at 15 fps with the resolution: VGA / WD1 / 4CIF / CIF at 25 fps.

The DVR can record one or two video streams (primary and/or secondary) from each channel. The video can be compressed using the H.265 method. 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. H.265+ can further minimize the streams in typical video surveillance scenarios.

Footage can be recorded 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 for specific events. Each channel can be configured individually in this respect. It is possible to change the resolution, quality, and frame and bit rates independently of the continuous recording settings. After the occurrence of an event (motion detection, camera tampering, etc), the DVR 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 with high detail and smoothness, while the recordings between events may have a much lower performance, taking significantly less storage media space.

The Enhanced IP mode allows to increase the number of supported IP channels. It disables smart events in analog channels and limits the HDMI/VGA output resolution to 1080p. The mode can be activated only through direct access to the DVR's menu.

Each channel can be independently set up for motion detection and VQD (video quality detection, which e.g. can send e-mails or notifications to alert the user whenever the image is out of focus, too bright, or discolored).
Two analog channels can be selected to detect virtual line crossing (and its direction) and intrusion within a rectangular area.
Users can also opt for the Enhanced VCA mode, in which virtual line crossing and intrusion detection are available in four channels. If the mode is switched on, the CVBS output will be disabled.

The iVMS 4200 client software enables users to manage Hikvision devices in IP networks. The software enables the configuration and management of NVRs/DVRs, IP and analog cameras in hybrid systems. The iVMS 4200 utility can remotely manage up to 256 devices on up to 4 monitors. One monitor can display images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifications, two-way audio transmission, and multi-level e-maps.

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.

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

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.
