Function
The camera uses MJPEG or H264 compression technology to provide
quality images. MJPEG is a standard image compression technology
applicable to different browsers without the need to install additional
software. H264 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.
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 performances at each client end.
Yes, you can use the snapshot function from the main control page.
Camera Installation
The camera is not waterproof, so a special waterproof cover must be
available for outdoor use. Please note that the waterproof cover may affect
the built-in pickup function of the camera.
• Check that the attached standard transformer is not damaged. Plug the
power cable and reboot the machine.
• If the problem remains, contact your dealer for help.
The camera uses a 10 or 100 Base-T Category 5 UTP network cable.
If you have a firewall in your network environment, please select HTTP
mode (Port80). Generally the port 80 is always open for the browser to
access the Internet.
