Question Answer and Solution
Function
What encoder and decoder
are used by the camera for
sounds and images?
The camera uses MJPEG or MPEG4 compression technology to
provide quality images. MJPEG is a standard image compression
technology applicable to different browsers without the need to
install additional software. MPEG4 is a next-generation image
compression standard and can provide high image quality at low
bandwidth.
The sound decoder uses PCM (Stereo, 16bit, 8kHz) compression
technology.
How many users are
allowed to view the camera
simultaneously?
The maximum number of viewers depends on the bandwidth of the
client accessing the camera. About 5~6Mbps are used to process
data of the camera, so the maximum number of viewers changes in
proportion to FPS and the resolution of the image. Obviously, the
higher the number of viewers, the lower the performance at each
client end.
Is it possible to catch the
image from the camera in a
real-time manner?
Yes, you can use the snapshot function from the main control page.

How to install and operate
