Q: How large are the images in Kbytes?
A: The size of the image depends on the resolution and the compression scheme used. An image of (352 x 288 or 352x240) that is compressed using MJPEG is only about 4-10 Kbytes. Higher resolution cameras such as the IQeye megapixel cameras, with resolution of 1200 x 1024, create file sizes as large as 80K bytes per frame. Since MPEG4 and H.264 improves compression by transferring only the difference between frames, we don't use frame size with these compression schemes. Instead we estimate an average data rate based on the resolution, frame rate and expected activity the camera will see. In general you can expect about 4 to 10 times improvement in compression using MPEG4 or H.264. To learn more about this take a look at our newsletter on this subject.
Q: How much bandwidth is used by an IP camera system?
A: The bandwidth depends on the number of cameras, the resolution of the cameras, the compression scheme used, and the frame rate of the cameras. To learn more about this take a look at our newsletter on this subject.
Q: Does the IP camera device have its own IP address?
A: Yes, it acts as a standalone web-server.
Q: What is the difference between MPEG4 and MJPEG compression?
A: MPEG4 provides better compression, but MJPEG provides higher resolution in some situations. MPEG4 improves the compression by transferring only the difference between frames. MJPEG supports very high resolution. For more information about the difference between MPEG4 and MJPEG take a look at our newsletter on this subject..
Q: Can I use an IP Network Camera for videoconference?
A: Yes, but it's not as good as general video conferencing solutions because there is some delay in the signals through the camera and network. if the cameras use MPEG4 or H.264 compression and support audio then it can be used for two-way communicaitons. For example you can use the which has a built-in microphone and provides simultaneous transmission of both audio and video
Q: How much bandwidth audio require?
A: very little extra bandwidth is required to add audio. It's usually less than 56 Kbits/sec.
Q: Which camera is best for my application?
A: It depends on your application. To determine the best cameras you need to answer some questions.
For more about how to select the right system take a look at our newslettern this subject or contact us for help in selecting the right system.
Q: Where can I get accessories such as replacement lens, zoom lenses or other devices.
A: Kintronics provides a choice of lenses, enclosures, brackets and video cameras.
Q: Do the cameras come with a PC application for storing and managing the video?
A: Some cameras come with very basic software. For applications that require 4 or more cameras we recommend additional software. We provide a number of optional software and hardware products for controlling cameras, viewing and storing the video on standard hard drives. Take a look at our website for examples of the software available.
