Thanks Sixwheeledbeast. I appreciate your help and I've read the article but it's beyond my level of technical ability I'm afraid. I'm taking from this that no CCTV system is totally secure and P2P, even though I have a new password everywhere possible, that is even more vulnerable than DNS and port forwarding. If you were to choose either one, which would you choose ? Or none? Does anyone know any experts who can help me secure my CCTV system in the Glos area, or is a secure CCTV system (even if built in the UK) an oxymoron?

Ok fair enough...think I need a course! With regard to the P2P - if it was hacked, would that provide a door to my whole network or just to my CCTV box? I'm not sure how all this networking works

Crumbs! I give up. Not really sure how to secure my cctv network then. Can any of you give me step by step instructions as to how to do it? If DNS is poor and P2P worse, then what else is there to enable remote viewing? With regard to the P2P - if it was hacked, would that provide a door to my whole network or just to my CCTV box? I'm not sure how all this networking works

In your view, are P2P any safer?

James.wilson....I'm so confused now. What do you mean? Can someone explain why DMZ is a bad idea? Could that be what caused me to be hacked? But on every user did it say...your account has been hacked please secure" by the side of it? Can someone elaborate please as I'm not very familiar with a lot of these terms but am willing to try to grasp it all.

Thanks. So if I understand this correctly, the DMZ was protecting me and was what put the error message on the box which was how I realise people today that I had an extra user by way of "system" ? Do you mean that or do you mean that it was what CAUSED it to be compromised in the first place?,

Do you mean passwords on my CCTV box, and which device are you referring to please (the CCTV box, the router or my pc's?)

Thanks guys. Yes, I had port forwarding on . Latterly it had been changed to DMZ I think, upon the advice of my installer as BT messed up my port forwarding (reset my router) and were about to do it a few more times as I had an issue with my Hub. What are the implications of both of these points please?

Hi EveryoneI've posted this on the DIY forum as a warning for other CCTV users, However, I'm in need of some techie networking help to advise me on what data, if any is likely to have been compromised by the hacking of my CCTV box. Some background, you may have seen some of my previous posts about problems with my old cctv box interfering with my Internet and also Live View on web interface not behaving. Well, I got a new system and while I was dismantling the old one and checking settings for transfer across etc, I noticed it had been hacked. Please see this link Your CCTV system was hacked! Can you prevent it?and Thousands of hacked CCTV devices used in DDoS attacksIn the first link, that's exactly what I found on my box - an additional user called "system" which said your box has been hacked please secure. I also had the same web interface issues with Live Preview. My installer put this in nearly 3 years ago and at the time he only told me to change my admin password which I did. I left the factory password alone as that's what I was advised to do. It was the usual Dahua 888888. So I think that's where and why it was hacked so easily. For what nefarious means I don't know. I haven't been burgled while this was going on, so it's not for that purpose. I did have all the internet issues whereby intermittently since the web interface issues (which is since it was hacked), and my internet would slow down so it was unusable even with an ethernet cable straight into the router. Then it would free up again for a while before it happened again. I don't know if that was hackers using my CCTV box as a route for DDos attacks (not that I now what they are, just that they use up all your bandwidth - can someone explain please?) or maybe it was the firewall kicking in on the router/home hub and stopping our access so we couldn't be hacked - is this possible in theory?My BIG question is though, with all this in mind, does anyone know if, once the CCTV box has been breached, home data on laptops, Macs, iPhones etc is compromised or could my theory about the firewall be correct? Edit - No need to post in 2 different forums, duplicate post in 'DIY installers' has been deleted, thanks.
