Hi My names is Frank and im from Mexico (english its not my first languague sorry) i work on a coffeshop and my DVR has been hacked twice, the ip changed to a strange one, not the local one i set, and the cam's names also changed to stuff like (hacked, firmware, upgrade instead of usual cam1, cam2, etc) I already change password but i want to know, is there a way to prevent it for happening again. There is a worker here who brings his laptop and he maybe tampering but im not sure. I read on some websites that with the dvr ip, ports and tools like hydra they can crack your pass and hack your dvr. Hope you can help a guy here, thanks and glad to be here. btw, my dvr is lorex
