NUUO Network Video Recorders - safe and efficient surveillance video recording
The information contained herein may be outdated.
NVR (Network Video Recorder) of NUUO is innovative plug & play device for full management of IP CCTV system. The main functions include live monitoring, recording of video streams, playback of the archives. This flexible NVR platform allows multi-server multi-client operation. NUUO NV-4080 K4108 NVR can record video streams from megapixel (up to 5 MP) and standard-resolution cameras, with frame rates up to 25 fps. Due to Linux OS, it ensures stable operation and resistance to computer viruses.

NUUO NVRs are used in all kinds of maintenance-free systems, where access is required in certain situations, usually after detecting an intrusion. Such systems are suitable for video surveillance of offices, factories, warehouses, stores, businesses, various buildings etc. The running cost of NVRmini connected with energy consumption is several times lower than in the case of a typical server - about 30 W instead of about 200 W!
The system is operated only remotely (via IP network). There is no need to create or define a monitoring center, because its functions can be performed from any point of the network. The connection is via Internet Explorer or client software. The former solution is convenient for its simplicity (no need to install additional applications), while the latter makes it possible to connect to several servers simultaneously.
The main task of NUUO NVR is to record data streams from IP cameras. The preparation consists in installing hard drives of appropriate capacity and configuring the system. The 8-ch and 16-ch models can hold four HDDs and support RAID 0, 1, 5, 10. Each channel can be managed independently, with scheduled recording or recording triggered by motion detection and/or an external alarm. A unique function is the possibility of triggering recording of a defined channel by an event in a different one. Any event can automatically initiate notification procedure (email/s to the defined operator/s of the system). Any event can be easily found with advanced event browser.
Special features of NUUO NVR mini
The uniqueness of solutions based on NUUO NVRs consists of many factors. The main ones are the advantages of using IP technology - the possibility of building distributed surveillance systems with ease of any extension and option of using megapixel resolution. The NVRs are based on Linux operating system which ensures stable operation, free from the errors and virus attacks often encountered on PCs. A unique feature of NUUO is the ability to view live and archived video simultaneously from all channels. The images are time-synchronized with each other and with sound which can be recorded as well (in every channel).
Cooperation with NUUO NVR software
NUUO client software cooperates both with NVR mini and systems based on PC servers and NUUO NVR software. It is suitable to create any video surveillance system containing manned and maintenance-free parts.
Surveillance software package NUUO SCB-IP+08 K3108
The manned part of the system is managed by the operator who is supported by image analysis functions and advanced searching features.

Some intelligent functions offered by NVRmini:
- motion detection,
- detection of a new object,
- detection of disappearance of an object,
- loss of focus,
- loss of video.
Security of the system
Solutions based on remote server-client concept have very important advantage associated with stability and security. They can allow access to the system resources for more than one operator/user. The access rights (accounts) can have many different levels assigned to individual users. A user's scope of operation may include e.g. one or more of the following activities:
- browsing of archives,
- live monitoring (of selected cameras),
- control of PTZ cameras.
Monitoring system architecture
Analog video surveillance systems are based on a star architecture with a DVR in the center and cameras as the points of the star. The DVR is the key device, when it stops operation the whole system becomes useless (does not provide video coverage). In IP systems, every device is more or less the point of a star. The integrating devices are switches or routers, less vulnerable to damage. Unlike analog cameras, most IP devices has the ability to write data on local SD card, thus preventing data loss in the case of LAN failure.
Adding cameras - channel configuration requires entering basic network parameters and identifiers (IP address, name and password). After clicking Add button the system will recognize the camera and update camera list. There is possibility of manual configuration (entering transmission port, data transmission protocol, camera vendor/model name).
Adding/configuring cameras to be used in NVRmini system
Camera status - after configuring cameras this window is used to check status of the cameras (connection, recording) and transmission parameters (frame rate, bitrate). The sum of the bitrates cannot exceed the total available bandwidth.
Recording schedule - can be independently set for each channel - days of the week, periods of the day. For example, the video from camera 1 is recorded from Monday to Friday, from 8.00 to 16.00, and on Saturdays from 9.00 to 13.00. During the rest of the time, the system can activate recording triggered by motion detection or alarm events. Detection of motion in one channel can trigger recording of other channels. Of course, motion detection and external alarm capabilities have to be implemented in the cameras.
System information - this window provides information on the NVR, including MAC address and total network flow (inflow, outflow). In the Enclosure Information tab (below) there is information on physical parameters inside the device including CPU temperature, fan speed, power rail voltages.
Live view - there are two ways to use the live view function:
- with Internet Explorer,
- with the Remote Live Viewer application (common for NVR mini and servers using NUUO software).
Live view of camera images
Playback - similarly to live view, the archives can be played back with web browser or remote Playback System application. In both cases the user chooses channels (cameras) and interesting dates/periods of time. NUUO NVR mini does not limit the number of simultaneously played back recordings.
NUUO playback window
Remote access via 3G - NVRmini allows remote access to archival recordings from cell phones/PDAs/tablets with 3G function. With this feature, the user can freely view the video from selected cameras from any location in the world (within a 3G service area).
Live view of camera images on a smartphone
The NUUO NVRs are designed for archiving of surveillance video from IP cameras in small and medium-sized systems without operators. Each of these compact NVRs has been equipped by the manufacturer with a robust software package. The systems based on the NVRs and the software show high stability, resistance to attacks, viruses and other threats that occur in IP networks. They can integrate many NVRmini units and provide access to the surveillance data to many authorized users.
