selfmade01 0 Posted October 20, 2014 hello. I could make a AVTECH AVC 761z-b 4 channel recorder buy is still new. Includes software CD. I don't know which Harddisk I can not install and where can I get the latest firmware. Also, I do not know if I can register for the free dyndns service of AVTECH. I am the second owner. The unit has never been used and is new. Does anyone know if I have a 2 tb SATA hard disk may use or to which storage capacity you can install a hard drive? where can I get the latest firmware? Does the dyndns service I can register the device or must I officially invite in a buy here? the original bill don't have the owner. Thanks for your help Greetings Jürgen Share this post Link to post Share on other sites
