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 or video frame, depends on the resolution and the compression scheme used.  An image with a resolution of 350 X 240 that is compressed using MJPEG uses about 4-10 Kbytes.  Higher resolution cameras, with over 1-megapixel resolution, create file sizes larger than 80K bytes per frame.  Most mega-pixel cameras use H.264 compression instead of MJPEG compression.  Since H.264 compression transfers only the difference between frames, it dramatically reduces the bandwidth.  In this case, we don’t calculate the bandwidth using the frame size. Instead, we estimate an average data rate based on the resolution.  The calculations consider the resolution of the camera, the 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 about IP Camera System Bandwidth.

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 an application for storing and managing the video?

A: Some cameras come with very basic recording software.  The problem is that software provided by the camera manufacturer usually works only with their cameras, so you may not be able to use another IP camera brand.  For applications that require 4 or more cameras we recommend a more universal recording system. We provide a number of optional software and hardware products for viewing real time and recorded video.  These systems allow you  to create a complete IP camera system that uses many different types of cameras.  Take a look at our IP camera video recording guide for examples of the recording systems available.
