axxn 0 Posted November 15, 2017 Hi everyone - I’ve purchased a home that has four cameras and an A-SDR402E-250 DVR, from ADT. Everything works great except it feels like this DVR is ancient. I can’t get it to go online, and even if I could, the manual says it only works with Internet Explorer. Can anyone recommend a cost effective replacement for this DVR? Hopefully something modern with iOS apps. I don’t have much experience with cameras, so I’m not sure if I can buy any model, or if only specific models work with the cameras that were supplied by ADT (presumably). Thank you!
