Tips to Optimize the Performance of MobileGo
MobileGo makes remote-monitoring possible as soon as you install it on your i-devices. With
normal network connectivity, you may enjoy the convenient functions it provides and
satisfactory video streaming quality. However, you might experience certain unstable video
display performance, for example, certain channels take longer to display the images upon
logging in, or the live view streaming is not smooth enough. Please consider the following
factors that are possibly influencing the performance of live view result:
How fast the Mobile server or NVR server can provide the output image
Mobile Server or NVR server would transform the original image to lighter format before
outputting it to the mobile client. However, the higher compression level or resolution the
original image comes with, the more CPU usage is required to process image-transforming,
and the longer processing time is needed to generate the output image before it can be
delivered.
Network quality
This is the major factor to affect the display result. With more bandwidth of the network
connection, your mobile client gets the images sooner and the streaming gets smoother.
There are several tips you may try to get better live view result as possible, given that your
network condition is not easy to control:
1. To preserve more CPU power for image-transforming (especially for Mobile Server, for
it shares the same CPU resource with NVR server) to generate the images faster and
more efficiently, you may make use of the dual-streaming devices on your site. Mobile
Server and NVR server support dual-streaming devices and would recognize Stream
1 output from video source. Simply use lower video format for Stream 1 for Live view
(640X480 resolution is recommended), while Stream 2 uses better format for the
purpose of recording. Thus it may take shorter for the mobile device to obtain the
image data and display the view.
2. As video stream with better compression level will consume more CPU usage for
Mobile Server or NVR server to decode the image, you may try using lower
compression levels such as MPEG-4 or MJPEG for high resolution video.
