GV-NVR Lite vs_QNAP VS-2008 Pro

1. GV-NVR System Lite Vs QNAP VS-2008 Pro
Article ID: GV38-11-3-24
Release Date: 3/24/2011
The GV-NVR System Lite is a light-weight and ultra-slim NVR system that can record video files directly
to the internal hard drives. We compared GV-NVR System Lite with QNAP’s VS-2008 Pro and
summarized the advantages of GV-NVR System Lite as below.
Smooth Live View
We compared the live view images of GV-NVR System Lite and VS-2008 Pro when they are connected
to up to 4 channels of 1.3 megapixel IP cameras. Under all codec types, GV-NVR System Lite shows
smooth live view when simultaneously connecting to 4 IP channels.
On the other hand, although claiming to support up to 8 channels, VS-2008 Pro starts to drop
frames when connecting to multiple megapixel cameras as indicated below. In addition, VS-2008
Pro can only support 30 fps at D1 or VGA resolution according to its software specification, which is
problematic as megapixel IP cameras are increasingly becoming the industry-standard.

2. Recording at Full Frame Rate
Videos from 4 channels of 1.3 megapixel IP cameras were recorded on GV-NVR System Lite and
QNAP VS-2008 Pro to compare the recorded frame rate. We can see that the GV-NVR System Lite
recorded 100% of the cameras’ maximum frame rates, while VS-2008 Pro was only capable of
recording part of the cameras’ maximum frame rates.
The test results of the GV-NVR System Lite were determined using the 4 GV-IP Cameras listed below.
The FPS specifications of the 4 cameras add up to 75 frames per second.
Ch Model FPS Specifications
1 GV-BX110D 15
2 GV-BX110D 15
3 GV-BX110D 15
4 GV-BX120D 30
For VS-2008 Pro, the maximum frame rates of the 4 third-party cameras used in testing MJPEG add up
to 52 fps, and the frame rates of the cameras used in testing MPEG4 and H.264 add up to 66 fps. To
see details on the third-party IP cameras used to obtain the VS-2008 Pro test results, please refer to

3. We simultaneously recorded a moving person using GV-NVR System Lite and VS-2008 Pro, and
captured the recorded frames during the same time period. As shown below, GV-NVR System Lite
recorded many more frames to ensure a smooth and detailed playback, whereas VS-2008 Pro
images show sudden movement and ghost image due to low frame rate.

The following two cameras were used to record the images.

4. Effortless File Export and Playback
After the video images are recorded, GV-NVR System Lite’s built-in software enables users to directly
export the videos as avi format. Recorded video clips can then be played back on any computer using
common media players. GV-NVR System Lite uses the more popular Windows file system to
make sharing recorded video quick and easy. Since VS-2008 Pro is a Linux-based NVR, users
have to transfer videos to a separate computer through network in order to export the avi video
files.

Time required to export Avi files 1 minute 10+ minutes
Exporting video files for evidence Network not required Network required
Level of difficulty Easy Complicated
From the diagrams below, we can see that exporting video files from GV-NVR System Lite is fast,
convenient and requires no network.

5. When VS-2008 Pro is not connected to network, users have to remove the HDD from VS-2008 Pro,
attach it to a Linux computer, read the video files with the correct file system (EXT3) and transfer the
files to a Windows system computer in order to export the Avi file.
Flexible Recording Modes
GV-NVR System Lite allows users to easily select among different recording modes including
round-the-clock, motion detection, sensor detection, pre & post recording and schedule recording.
VS-2008 Pro users, however, can only change the recording mode from a separate windows-based PC.
Furthermore, VS-2008 Pro’s motion detection function relies on the third-party IP cameras and
is only available when the connecting IP camera supports motion detection.
Support for RTSP and PSIA
GV-NVR System Lite and GV-IP Cameras all support RTSP and PSIA protocols, whereas VS-2008
Pro does not support RTSP and PSIA protocols.

6. All-In-One Solution
While QNAP users can only integrate its network surveillance systems with third-party IP cameras,
GeoVision offers an all-in-one solution for network surveillance. A wide variety of GV-IP Cameras
available not only ensures full compatibility with GV-NVR System Lite, but also significantly
reduces troubleshooting time and RMA costs when the need for technical support arises.
