d13avo 0 Posted September 23, 2015 First of all hi to all the knowledgeable folk on here and I hope somebody can help me. I have owned a Avtech AVC761Z since October 2007 but recently developed a HDD fault and I could not see my cameras over the internet. I did a quick search and was recommended to Max at MAP security who has just sold me a new Avtech KPD677DEZ so I thought it would be simple to enter my existing settings and be back up and running but no. The software has obviously been updated and there are different options and no matter what I do it does not work out of my network. I can login to my cameras when connected to my wifi but if I try to do it with my 4G it does not work. I have a paid subscribed dyndns account and I have set my router service, firewall inbound rule and told the router to use a dyndns but still nothing. Please can someone help as I have been sat in my loft with this DVR and laptop for hours. Thanks Paul Share this post Link to post Share on other sites
