Will I be able to access my Lorex security system and monitor my house remotely if the security system is installed in Poland and I am in another country or in Poland?
Yes, you can view your cameras if you're outside your network, or in another city/country. There is a support page which provides all the necessary instructions including the Remote View procedure along with the auto-port forwarding procedure. Browse to the link posted below and then use the menu on the right navigate to other topics.
