I need a new camera system for my office, and I’m between the Arlo and Lorex systems offered at costco. I already bought 4 Arlo Pro 4s but I’m a bit unhappy with the image quality and lag, though I do love the mobile app integration. Wondering if I should return and get the Lorex Fusion system instead. Main questions I have are:

1. Has anyone used the mobile app and cloud client? Are they any good and how is the UX?
2. Is it easy to access the cameras and recordings remotely, either via PC or mobile app?
3. Is it easy to seek to points of interest in the recordings? E.g. seek to timepoints where motion was actually detected? One thing I actually like about the Arlos is that I don’t have to seek through hours of footage to figure out when someone may have, say, opened a door.
4. Can the NVRs be connected to the network wirelessly, or do they need to be connected via ethernet?

Also just FYI, I have existing POE cabling run through the office.
