Watch out for the web interface having an iframe linking to some malware site. The last ones I got have that "feature" in the firmware. Its ok because the AV blocks it but I hate to think what would happen if it didnt, and I dont know what effect adding the cameras IP address to trusted sites so the active-x runs would have on the linked malware in the iframe if at all.
My last 2 cameras are sitting on a shelf till the vendor either gets me malware free firmware or I will be doing a complaint for a refund on aliexpress.
