CCTV network monitoring of switch port bandwidth

Recommended Posts

I know you can monitor CCTV network switch ports for bandwidth greater than a given threshold. In addition to determining whether the network has enough bandwidth to properly operate, what other highly useful things can you learn from CCTV network switch ports surpassing a certain bandwidth threshold?

most switch ports are at least 100mbps. A camera usually only uses a few mbps, so its not really a concern. Also a good idea to isolate the cctv switch on its own network so that you dont interfere with network users.

You can use SNMP monitoring of SNMP enabled switches (most decent switches support SNMP), what you want to look for is drops/loss and collisions they point to problems in the physical cable connection. If there is loss or drops this can impact the TCP sliding window for TCP sessions (if you are using TCP for the camera stream) which can affect your ability to stream in HD.

 

Also some switches support PoE power use in SNMP which could be handy for tracking power usage.
