Hello, I've emailed you a link to a better app that you might find useful
Open the app on your device once you have completed the download and you will see a cloud login screen. Ignore that and scroll down and you will see a picture of a yellow television. Click on that, and at the bottom right of the screen, there will be an + icon, you will have to click on it
The device will attempt to contact its owner
Then scan the QR code on your DVR and enter the password for your DVR after you have scanned the code
All you need to do is click the save button at the bottom
