Digital Video Recorder

Nusoft's VR series of digital video recorders (DVR) provides various video monitoring and playback features in combination with intelligent image analysis mechanisms. Its hardware compression (H.264) produces real-time D1 resolution video, which means you can view clear and fluid recordings. Together with timely alert mechanisms, it performs to the stringent surveillance needs of businesses.

Access to the device's various features and settings is obtainable through a browser. Its user-friendly management interface in combination with context-sensitive help (via help buttons) facilitates its operation and management

Capable of producing D1 resolution and high quality frame rates (both live monitoring and recording). It satisfies various monitoring scenario requirements of businesses.
Uses a digital signal processor (DSP) in its hardware to handle video compression from each camera. The process is handled by the dedicated hardware compression chip, dramatically reducing the load on the CPU.
Incorporates H.264 video compression into its design, reducing the required amount of storage space and the load on the network.
Provides both video and audio channels, enabling a more complete surveillance.
Provides intelligent detection, recognition mechanisms, etc., presenting the ideal solution to the business's monitoring requirements.
Provides 3G mobile phone applications, enabling remote surveillance.
Supports alerts by SMS message, email, etc. The device notifies the surveillance administrator immediately of the event so that action can be taken promptly.
Provides convenient access to its settings through a browser.
Supports online viewing and searching via a browser.

1. Real-Time D1 Resolution

The Nusoft VR series hardware-based design produces D1 resolution (720x480 NTSC or 720x576 PAL) in real-time (30 fps NTSC or 25fps PAL). This level of clarity and fluid motion makes it ideal for a range of situations due to its capability to distinguish fine details such as text on documents, thus making it ideal for surveillance in banks, etc.

2. Hardware Video Compression

Nusoft's VR series uses a digital signal processor (DSP) in its hardware to handle video compression from each camera and produce D1 resolution. Unlike software compression, the process is handled by the dedicated hardware compression chip, which dramatically reduces the load on the CPU. Freeing up the CPU allows it to concentrate on other processing tasks resulting in greater efficiency and effectiveness.

3. H.264 Video Compression

M-JPEG and MPEG-4 are the video compression formats most commonly used amongst the majority of digital video recorders on the market. The Nusoft VR series encodes each camera's video stream feed using H.264 and consequently reduces video sizes by as much as 50 to 80 percent in comparison to M-JPEG and MPEG-4 formats. This significantly minimizes the required amount of storage space and reduces the load on the network,
but most importantly still maintains a high level of video quality.

4. Multi-Tasking Capabilities

The Multi-Tasking capabilities of the Nusoft VR series are ideal for PC's multi-core processors. Live monitoring, recording, object searching, playback, event alerts and remote monitoring from multiple users can all be performed simultaneously without any significant performance degradation.

5. Synchronized AV Recording

The device features audio input channels to accommodate the sound from any attached cameras. Without the presence of audio, recordings can lack some vital information that is needed to paint a complete picture and provide sufficient evidence.

6. Remote Monitoring/Configuration Access

The Nusoft VR series provides convenient access to its settings through a browser. In addition to settings configuration you can also view the stream of each camera's live/recorded video in real-time D1 resolution, perform searches, etc.

7. Video Capture and Snapshot

The Nusoft VR series provides you with Snapshot and Video Capture. Snapshot enables you to capture a single image from the previously recorded videos and the live recording. Video Capture enables you to capture the period of desired recording and save it as an AVI file.

8. 3G Mobile Image Alert

The Nusoft VR series is capable of sending any images triggered by alerts directly to a 3G supported mobile device using MMS technology. By viewing the image via a mobile device, the supervisor will gain an instant insight into the situation.

9. Hardware-Based Motion Detection

The device's hardware performs all the motion detection features, preventing CPU overloading from hampering the system. Personnel entering the specified motion detection zone will trigger an alert (email, SMS message, etc.). Aside from this, to prevent image noise or changes in ambient lighting triggering a false alarm, the device provides a detection sensitivity threshold setting and various other intelligent mechanisms.

10. Online Playback

When viewing videos remotely, the majority of DVR devices require you to first download the entire file and install a compatible media player in order for it to be viewed. Nusoft provides you with comprehensive playback controls that can conveniently be used to view videos remotely. You can find the desired segment effortlessly by using time increments and adjusting the speed (x1/16, x1/8, x1/4, x1/2, x4, x8, x16 and x32) or direction.

11. Instant SMS Message Alerts

In the security surveillance field, time is a critical factor. To ensure the timely notification of the relevant personnel, the Nusoft VR series provides instant SMS Message Alerts in addition to alerts via email. In addition, the device can send the video from the triggered alert to a specified FTP server.

12. Object Search

Instead of having to manually view and search though recordings to locate the time when a fixed object goes missing, the device provides an Object Search mechanism. Simply by specifying the area the object was originally located in, the device can automatically locate the exact time that the object went missing.

13. Real-time Viewing on 3G Mobile Devices

During the times you are away from your business' premises and you receive a notification from your security system, what do you do? Hurry back to inspect the business' premises or call the police immediately? Or could it just be a false alarm? Nusoft features remote viewing using a 3G mobile device. Instead of accessing a PC to view it, you can see the real-time surveillance anytime and anywhere through your 3G mobile devices.
