FAQs IP Cameras

Frequently Asked Questions or FAQs about IP Cameras

On-Net Surveillance System

Q: What makes the network IP cameras different than a CCTV video camera?

A: CCTV cameras connect to a video monitor or DVR using a coax connection, while IP cameras connect directly to the network using a RJ45 connector and have their own IP address. That means the camera has intelligence and can be shared by many PCs using web browser and the video recorded using video management software or a NVR.

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 with a resolution of 350 X 240 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 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 20 to 30 times improvement in compression using H.264. To learn more about this take a look at our newsletter article on this subject. .

Q: Does the IP camera device have its own IP address?

A: Yes, it acts as a standalone web-server.

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 communications. For example you can use the Sony dome camera which has a built-in microphone and provides simultaneous transmission of both audio and video.

Q: Do the cameras come with a PC application for storing and managing the video?

A: Some cameras come with very basic software. The problem is that software provided by the camera manufacturer only works with their cameras so you can’t use another brand. 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 IP Software guide for examples of the software available.
