Easy installation
Setup CD-ROM simp lifies the i nstall ation. Inser t the Se tup CD-ROM and autorun program should start the application automatically. This program automatically finds Network Camera on the network.
High-Speed Motion JPEG
Network Camera has an integrated web server. Motion JPEG displays up to 15 frames per second, if the network provides enough bandwidth. To conserve bandwidth, JPEG - Regularly Refresh can be selected from Top Page. Image Resolution, Image Quality, Refresh interval, Limit time of Continuous Motion
JPEG and On the Air time features can control the image field.
Multi-Camera Screen
Using Multi-Camera screen you can simultaneously view up to four Network Cameras at various locations. Clicking on each Camera Name switches to the Single Camera screen from the Multi-Camera screen.
Multi-Client Access
Network Camera allows up to 10 users to view Motion JPEG image simultaneously. Users can access the Top View Image screen (Single Camera/ Multi-Camera screen ) fro m the ir o wn l oc ati ons . N o te that as th e num be r of users simultaneously connected to Network Camera increases, the overall motion performance will decrease.
External I/O (Input/Output)
The external sensors/devices such as a door sensor can be connected via the External Sensor Input. The external sensors/devices are customer provided. The alarm/timer trigger can activate the Image Transfer feature, which can send the images via e-mail or FTP (File Transfer Protocol). External Device Control Output can send a signal to activate the external devices such as a light around Network Camera.
