Hello everybody. As always, sorry for bad english.
Today, a friend (who has a CCTV system in your company) said that a few days ago had managed to view the cameras from another company on your smartphone. According to him, the company that provides the tracking service, reported to be a problem when using the same model of DVR. That may have been a conflict of IPs, or something ... honestly, looks like an attempted invasion. It is very easy to break into a network and view the IP or analog cameras within the same network?
