For the normal user I think this is the easiest system I have found
I am not an expert so a lot of what I have heard from the experts about the video lag has not affected me. I have had several systems all of which I have ended up hating with a passion. I hated Arlo for their setup and re-setup procedures. I had to reset this system so many times I was about to explode. I was told by Arlo that the new system out was much better, so I tried a couple cameras and NOPE piece of crap, then they had the direct to the cloud connection, same issues. Every time the system lost synch, I had to reset it, and I could not do it without the help of the technicians. Thankfully for me, I was able to sell all the cameras for about a $100 loss only. Ring, yup it rang me batty enough said, there were a couple others that were just as bad as the rest I was lucky enough to have purchased them, tested them and sent them back for a full refund. Due to medical issues my friends and family wanted me to install cameras in my house in the event that I had another issue where I passed out, got hurt and couldn’t get up again. This system I decided to try and send back if it was bad and I found the cameras and everything on refurbished list, so I saved a good deal of money.So, I got the cameras first and they were delivered next day. I went to set up the base station and followed the guide on the app and it was user friendly, a couple things I did have to try to decipher but that was my own fault. I had 3 cameras and a base station wired and running in under 2 hours. Would have been faster but the cameras and base station had their own separate updates.So far, I love it, I love the cameras, and I love the doorbell now as well. I plan to continue to add to the system.

Excellent but with a caveat.
Good picture and function. Battery life is lacking however. I would recommend using the Balanced Surveillance setting to get the best of both worlds out of it and get an extra battery to optimize up time. One star off for battery life but I will still give it a recommendation.

I love always having an extra battery!
This is great because we can always have an extra battery ready to go, and there is no downtime when the doorbell battery dies.

Keeps me aware of front door interactions.
Could last longer but at least itâs easy to swap the battery.
