Hikvision DS-7732NI-I4 is a modern IP network video recorder capable of monitoring, recording and playing back images from 32 IP cameras of megapixel resolutions, up to 12 MP. This standalone NVR with VGA (up to 1080p) and HDMI (up to 4K) outputs can be directly connected to a monitor or television, without a need for an additional computer. The high processing power and increased input and output throughput of NVRs from I series is especially useful in the case of connecting cameras with 4 MP or higher resolutions.

The local recording and network transmission uses H.264+ or H.264 compression methods that provide good image quality with relatively small bandwidth and disk space consumption. The H.264+ compression is especially effective in the case of static or quasi-static scenes, allowing for higher compression ratios with preservation of image quality comparable with H.264. This further saves network and memory resources.
Four SATA ports enable the user to install 4 hard drives with total capacity up to 32 TB. Additionally, the NVR supports NAS (NFS) and SAN (iSCSI) disk arrays. In the case of disk space overflow, the newest data overwrites the oldest recordings. Built-in USB ports allow for connecting external memory sticks or disk drives in order to copy some files.

IP CCTV systems based on Hikvision IP cameras and NVRs can be configured for 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.

HIKVISION NVRs in IP networks can be controlled via IVMS 4200 software. The software allows for configuration and management of NVRs/DVRs and IP cameras. The iVMS 4200 utility can remotely manage up to 256 NVRs/DVRs. The user accounts can have different access/management rights, from the highest level of "administrator" to individually limited "guest" levels.

iVMS-4500 is a mobile application for smartphones running Android, iOS or Windows Phone operating systems. It can be used for live monitoring and playback of images from DVRs, NVRs, IP cameras via Wi-Fi, 2G or 3G networks.

The camera can operate outdoors or indoors. Its housing with high ingress protection rating (IP66) protects the electronics against adverse weather conditions. The built-in IR illuminator has a range of up to 30 m. The camera can be powered with a 12 VDC power source or via PoE (802.3af).

Ezviz (EasyVision) is a free service which can be activated in Hikvision NVRs and IP cameras. This free service allows less advanced users to easily access to the video from the cameras via the Internet, without forwarding router ports. To enable remote access, the user should only connect the device to the network (which requires a valid IP address and appropriate gateway settings). The next step is the creation of user account at the www.ezviz7.com website. The account can accommodate devices in a local area network (with activated Ezviz service). The devices will be available from anywhere via the Internet.

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.
