APPENDIX B. FAQ：
General questions for IP Camera
Q1：What is IP Camera?
A: IP Camera is an independent system that can connect to network or wireless network directly. It
is different with general camera. It is an all-in-one system with built-in CPU and transmits
high-quality video monitoring images via browser control and network. The IP Camera can setup
or view the Web browser of remote PC/Notebook through network.
Q2: How many IP Cameras are allowed to be connected in LAN?
A: Eight IP Cameras are allowed to be connected in LAN at one time. Transmitting too many
packets through LAN might lower down the efficiency of the network.
Q3: What algorithm that IP CAM uses for compressing images?
A: IP CAM uses JPEG file format to compress the images and uses dynamic JPEG image
compressing technology to process dynamic videos. Thus it can ensure both high-quality screen
and high-compression ratio of the images. JPEG is a standard industry image compression
technology, which can apply in various programs of browsers and does not need any plug-in
software for viewing.
Q4： How can I promote the image quality?
A1: Please make sure the color setting for your monitor display is 16 bits or above. 16 color or 256
color will reduce the image quality for your monitor display and result in bad quality of the video
images,
Q5: Can I capture the static images from IP Camera manually?
A: Yes. You can capture the static image form the IP Camera. While browsing the screen on
network, right click the mouse on the static image or click
Snapshot button on the
screen to save the picture with another filename. You can click the Re-arrange button on the
browser to re-capture the new screen via IP Camera.
Q6: Can I use IP CAM outdoors?
A: The IP CAM is not waterproof. You have to attach waterproof cover on it for using outdoors. By
the way, we do not recommend you to do so.
Q7: What kind of network cable is necessary for IP CAM?
A: Standard RJ-45 Category 5 UTP twisted pair is necessary for IP CAM IP CAM to connect 10
Base-T and 100 Base-T network communication.
