Hi, noticed a feature on the Dahua DVR (P2P), which requires no port forwarding etc... 1. How does this work 2. How secure or vulnerable does it make the network or cctv when enabled thanks.

If you use p2p you're viewing images via a third party website/server, the dvr updates the remote server with ip address etc, useful if you dont have a fixed ip address, ie, if you have a power outage, or router reboots, it may assign a different ip address to the dvr, which the dvr then passes to p2p. Obviously you are viewing via a 3rd party, so it's not as secure as going straight to the dvr using the www, also if the hosting server/site fails, so does your p2p. Imo it's easier to use, and for just domestic use, or none critical places, I don't feel there is any major problem. I'm sure others here will elaborate and discuss the ins and outs.
