a few general questions about IP system

Recommended Posts

Also Soundy is spot on,

3. Almost all cameras currently available have only 10/100 ports' date=' so your entire network doesn't have to be gigabit. We commonly use a switch that has eight 10/100 PoE ports, and two gigabit ports - the cameras connect to the PoE ports, and the DVR and NAS connect to the gigabit port.[/quote']

 

Thats a friggin brilliant way to do it

Thanks It was mainly done as a cost-effective measure, as all-GbE switches are still a bit spendy... or were when we started implementing this setup about four years ago; they're a lot cheaper now.

 

I've posted this plenty of times... this is a basic layout of the network we use, tied into the customer's network so they have VPN access, and so the DVR and NAS have internet access to send alert emails:

So your "surveillance" switch doesn't connect back to first switch or router via gigabit? 10/100 is ok?

You mean to the "Office LAN Switch"? No, 10/100 is fine... the ONLY reason it links into that network at all is for internet connectivity, mainly so the DVR and NAS can send alert emails, and so the IT manager and select people at head office can connect the remote client via VPN. The bottleneck is always the internet connection itself, anyway (probably 1-2Mbps upstream on most sites).

 

If you remove that connection, the whole camera/DVR/NAS system still functions on its own.
