Processors and RAM of PC based DVR's can usually handle the load as well. The main constraint is usually the minimum bandwidth requirement.* Most DVR's can handle up to Terrabytes of storage space. Planning up front is invaluable so you can obtain the right hardware, (DVR's, video capture cards, network switches, etc.) software and be sure that your connection speeds are sufficient to handle your remote recording / viewing requirements. This handy tool will be of great use when you need to determine the minimum requirements for bandwidth, hard drive space, processor and RAM for your surveillance system remote viewing and recording. Please click here to download this spreadsheet calculator: IP camera network bandwidth calculator. IP Camera Network Bandwidth CalculatorTo help plan your IP camera system, NUUO surveillance (a partner of CCTV Camera Pros & manufacturer of IP camera software) has provided a free bandwidth calculator to help installers plan their system. You can also use this Internet connection speed test to run a report.

You can contact your ISP (Internet Service Provider) to find out the speeds that you currently have available and also to inquire if faster plans are available in your area.

This means that on the network where your camera is located the Internet connection must support an upload speed of at least 650Kbps and the Internet connection where your remote DVR/NVR os located must have at least a 650Kbps download speed. However, once you get involved with more than one IP camera and you want to record high-resolution video and high frame rates, the required Internet connection speed requirements increase exponentially and in many cases is not realistic using a standard DSL or cable modem-type of Internet connection.įor example, if you are recording 2 IP cameras using MPEG-4 video compression, with a screen resolution of 640 X 480 pixels at 7.5 frames per second (1/4 real-time video), you will need approximately 650Kbps of bandwidth. If you are not recording many cameras and do not need high-resolution video, then the bandwidth requirements will be more minimal. Please note that even if you are recording locally, you need to consider these items in planning your local network. You will have to account for all of the above items to plan for the bandwidth requirements of an IP surveillance system.
