Updated review

Now you can navigate between cameras without returning to the feed list. This is a big improvement but still feels clunky not being able to swipe as you would in most other apps when viewing imagery or video.

Wish you could customize names of servers in the list - I end up with identical servers (one for when I’m signed into the local network and one for when I’m away) but you just have to try until it works because they are indistinguishable. Our security company says that’s just how it is.

Upgrade to server version 3 resolved issues mentioned in previous reviews, nice! Feeds seem to be reliable, no crashing.

Axis P8221 I/O mod doesn’t load

This app works great for normal remote access. However when I added an Axis P8221 (licensed) to switch “on site” devices the interface does not load as it does on my PC. The window just acts as if it’s buffering or trying to load but never does. Tech support acknowledged the problem and said hopefully the next update would address the issue. ?????

Smart Motion Search !!! 😁

The latest version with smart motion search is a total game changer! 😊 Now I can quickly scan hours of footage on the iPhone/iPad from anywhere instead of having to sit down with a PC/laptop.

Just for the record, we have a v2.5 blackjack cube and I'm running iOS 10.3.3 and the v19.2 June build still works great. Resolution transcoding as well as smart search. 😁

The v19.1 May build would not even connect to our server.
