Hi Michael72,
There should be several ways, many of the Q-see products I have seen at Costco clearly look like Dahua OEM products - and while I have not looked at the 4K indoor cameras from Dahua believe those also to be Dahua OEM.
Thus the first thing I would look at would be the Dahua apps and see if I can get it to work with them:
iDMSS & gDMSS | Dahua Technology - Dahua Technology
I checked "easy4ip app" which was recommended by Dahua but this app doesn't have a good reviews. Do you know any other app I can use for Q-See Wi Fi camera's? Also, the Q-See camera's giving only 2 options: record to mini sd or to their Cloud, which has a monthly fee. I was wondering id there any other way for me to storage/save the video's? Thanks!
