Well I thought you were going to transmit (stream) the video acrosss the open |
| 9 |
internet. If you do, the bandwidth consumption becomes an issue. |

Correct you are, if you are going to build a campus (local) video surveillance |
| 16 |
system. When you stream the video over the Internet, all sorts of issues emerge. |
| 17 |
Chief being the amount of bandwidth you consume. |

There are lots of tools for measuring bandwidth. Personally, I isolate the |
| 21 |
video system into a single ethernet port, and then measure the bandwidth |
| 22 |
consumption on that single (isolated) port. Your ISP may give you fits also |
| 23 |
about streaming video. Many ISP look for such things and block ports if |
| 24 |
very much is used. Leaving the bandwidth up continuously is also risky |
| 25 |
as the many ISP(police) software identify and block such activities. |
