Appendix C. Performance Information
1. Video Performance Information
The video quality is dependent on the video parameter settings and the network
quality. If you want to have a better video quality, you will usually set higher resolution
and higher frame rate. This is fine when you are viewing the video locally in the same
network. But when you want to see the video remotely through the Internet, you need
to know the Internet speed (bandwidth) connected to your home network. If the
“Internet speed” setting of your IP camera is very large, but your real Internet speed
(bandwidth) is relatively low, the video quality could be very bad. In some worst case,
the video display could be disconnected. In order to have the best video quality, you
better have broadband service from your ISP and set the “Internet speed” of the IP
camera a little lower than the real Internet speed provided by your ISP.
Also need to notice that when multiple users are displaying the videos from the
same IP camera at the same time, the video bandwidth times number of users will be
needed for the Internet speed.
2. WiFi Performance Information
The WiFi performance is dependent on the distance between the IP camera and
the AP (Access Point) / router and dependent on the number of devices connected to
the AP/router. Also need to consider that if there are any barriers like wall or floor
between the IP camera and the AP/router. IF there are some open space between the
IP camera and the AP/router, you also need to know that the performance will be
interfered in rainy day. The antenna gain and it’s direction in the AP/router will also
affect the WiFi performance. In general case, when the IP camera is set to the default
video setting ( 1M bps) and there are no other interferences between the IP camera
and the AP/router, the working straight distance is about 100 meters between IP
camera and the AP/router.
3. Motion detection Performance Information
The motion detection is based on the video change of the camera, any
video change including moving objects(car, human, pet, door, leaves) and
even light change (turn on/off light or light change in the morning/evening)
could trigger the detection. The sensitivity of the motion detection is based on
the size of the moving objects, more sensitive means the detection of smaller
objects.
