GeoVision : CCTV Solutions : GV-NVR Lite VS QNAP VS-2008 Pro

  1. 1. GV-NVR System Lite Vs QNAP VS-2008 Pro Article ID: GV38-11-3-24 Release Date: 3/24/2011The GV-NVR System Lite is a light-weight and ultra-slim NVR system that can record video files directlyto the internal hard drives. We compared GV-NVR System Lite with QNAP’s VS-2008 Pro andsummarized the advantages of GV-NVR System Lite as below.Smooth Live ViewWe compared the live view images of GV-NVR System Lite and VS-2008 Pro when they are connectedto up to 4 channels of 1.3 megapixel IP cameras. Under all codec types, GV-NVR System Lite showssmooth 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 dropframes when connecting to multiple megapixel cameras as indicated below. In addition, VS-2008Pro can only support 30 fps at D1 or VGA resolution according to its software specification, which isproblematic as megapixel IP cameras are increasingly becoming the industry-standard.GeoVision Inc. 1 Revision Date: 3/24/2011
  2. 2. Recording at Full Frame RateVideos from 4 channels of 1.3 megapixel IP cameras were recorded on GV-NVR System Lite andQNAP VS-2008 Pro to compare the recorded frame rate. We can see that the GV-NVR System Literecorded 100% of the cameras’ maximum frame rates, while VS-2008 Pro was only capable ofrecording 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 30For VS-2008 Pro, the maximum frame rates of the 4 third-party cameras used in testing MJPEG add upto 52 fps, and the frame rates of the cameras used in testing MPEG4 and H.264 add up to 66 fps. Tosee details on the third-party IP cameras used to obtain the VS-2008 Pro test results, please refer toAppendix A.GeoVision Inc. 2 Revision Date: 3/24/2011
  3. 3. We simultaneously recorded a moving person using GV-NVR System Lite and VS-2008 Pro, andcaptured the recorded frames during the same time period. As shown below, GV-NVR System Literecorded many more frames to ensure a smooth and detailed playback, whereas VS-2008 Proimages show sudden movement and ghost image due to low frame rate.GV-NVR System Lite Frame 1 Frame 2 Frame 3 Frame 4 Frame 5 Frame 6 Time: 16:22:12VS-2008 Pro Frame 1 Frame 2 Frame 3 Time: 16:22:12The following two cameras were used to record the images. Camera Model Frame Rate Resolution # of Channel GV-NVR System Lite GV-BX110D 15 fps 1280 X 1024 1 VS-2008 Pro ACTi TCM4301 18 fps 1280 X 1024 1GeoVision Inc. 3 Revision Date: 3/24/2011
  4. 4. Effortless File Export and PlaybackAfter the video images are recorded, GV-NVR System Lite’s built-in software enables users to directlyexport the videos as avi format. Recorded video clips can then be played back on any computer usingcommon media players. GV-NVR System Lite uses the more popular Windows file system tomake sharing recorded video quick and easy. Since VS-2008 Pro is a Linux-based NVR, usershave to transfer videos to a separate computer through network in order to export the avi videofiles. GV-NVR System Lite VS-2008 ProTime required to export Avi files 1 minute 10+ minutesExporting video files for evidence Network not required Network requiredLevel of difficulty Easy ComplicatedFrom the diagrams below, we can see that exporting video files from GV-NVR System Lite is fast,convenient and requires no network.GeoVision Inc. 4 Revision Date: 3/24/2011
  5. 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 thefiles to a Windows system computer in order to export the Avi file.Flexible Recording ModesGV-NVR System Lite allows users to easily select among different recording modes includinground-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 andis only available when the connecting IP camera supports motion detection.Support for RTSP and PSIAGV-NVR System Lite and GV-IP Cameras all support RTSP and PSIA protocols, whereas VS-2008Pro does not support RTSP and PSIA protocols.GeoVision Inc. 5 Revision Date: 3/24/2011
  6. 6. All-In-One SolutionWhile 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 Camerasavailable not only ensures full compatibility with GV-NVR System Lite, but also significantlyreduces troubleshooting time and RMA costs when the need for technical support arises.GeoVision Inc. 6 Revision Date: 3/24/2011
