PoE
The VB-C500VD/VB-C500D supports Power over Ethernet (PoE*) technology, which enables
simultaneous video/audio data transmission and power supply by simply connecting a PoE
HUB and a single LAN cable ( P. 2-6). When connecting to a PoE HUB, you need not
connect a power adapter to the camera or perform any power wiring.
* PoE stands for Power over Ethernet, which is compliant with the IEEE 802.3af standard by the Institute of
Electrical and Electronic Engineers.
Install-Free VB-C500 Viewer
This camera has a built-in VB-C500 Viewer, so its data can be viewed using a browser.
Accordingly, there is no need to install a PC application. Also, three levels of user privileges
can be set, including [ Administrator ], [ Authorized User ] and [ Guest User ].
Canon's Network Video Processor "DIGIC NET"
The camera incorporates DIGIC NET that offers high network distribution performance and a
range of intelligent functions to achieve high image quality and high-speed communication
such as simultaneous distribution of JPEG and MPEG-4.
Simultaneous Distribution of JPEG and MPEG-4
Video compression adopts JPEG/MPEG-4 to achieve high image quality/high frame rate of up
to 30 frames per second*
1
in VGA (640x480). Up to 30 clients*
2
can view the same image
simultaneously.
*1 Note that the frame rate may drop depending on the performance of the viewer PC, number of clients
connected at the same time, network load, etc.
*2 In MPEG-4, up to 10 clients can be connected at the same time.
Multi-Streaming
In JPEG, image can be distributed in three sizes (640x480, 320x240, 160x120) at the same
time.
High Quality Video of Moving Subjects
The VB-C500VD/VB-C500D utilizes a progressive-scan CCD to allow for the capture of noise-
less, high quality video of moving subjects.
Selectable Metering Modes for Various Shooting Conditions
Image can be captured by switching the metering mode* to one of three options, including
Center-weighted, Average and Spot, according to the shooting condition of the camera.
( "Setting Exposure" in Operation Guide )
* Brightness (light quantity) of the subject is measured to adjust the exposure.
