I can't find any guides or helpful forums on how to securely setup a DVR system for remote video surveillance. And by setup I mean - what kind of DVR and how to setup/connect the system to the Internet so it has a good level of security?
From what I've read many DVR's have some sort of default passwords that allow hackers/bots that scan the network to gain almost instant access, yet I didn't find any solutions to this problem - are all DVR's really that vulnerable? Then I've stumbled upon some vague advice on setting up VPN for connecting to the DVR, which again I couldn't understand.
Can you provide advice? Is there a place that provides advice on this subject? If I go with a PC-based DVR solution - is it the same as setting up a PC for remote access, or the DVR card/software would still add the vulnerability of default passwords?
