The high-resolution 1/3 type Interline Transfer CCD with 380,000 effective pixels reproduces superbly detailed images in true color.
Produces high-quality images in the Motion-JPEG format with resolution of up to 640 x 480 pixels and a maximum frame rate of 30 fps.
Simply connect with a LAN cable on the Ethernet network and the camera is activated and can be controlled via connected PCs.
*PoE enabled switch or power injector is required for PoE operation.
Alarms can be activated based on motion within a defined area. Motion detection can also start video recording on a connected computer.
Provides higher sensitivity under low illumination. When the Easy day/night is set to ON, minimum illumination is 0.4lx F1.2 (25IRE).
The VN-C20U features a built-in web server that allows you to connect your surveillance system directly to the Internet without having to route it through a dedicated web server. This allows you to deliver high-quality, real-time images to any Internet-connected computer in the world, giving you unlimited flexibility.
The VN-C20U features a hybrid design with both an IP output and a Monitor video output which produces a picture equivalent to an analog camera, and allows simultaneous output of both.
- Multicasting capability
- FTP client/server function
- 10Base-T/100Base-TX/Full/Half/auto negotiation
By installing the VN-C20U's built-in viewer on your PC, streaming camera images can be monitored with the Internet Explorer. Snapshot recording, alarm signal reception, and various settings are also possible with the viewer.Notes:
- The VN-C20U's built-in viewer does not have a recording function.
- Compatible multi-camera browser VN-RS800U will be available in August 2006.
Initial setup is easily achieved by Internet Explorer. Various operating parameters can be similarly adjusted.
Settings for camera ID, iris, AGC, white balance, easy day/night, etc.
Settings for frame size, picture quality, frame rate, etc.
Settings for up to 5 actions when there is an alarm.
