Bests & Worsts Reviews from Amazon

I had multiple Amazon packages stolen off of my front porch yesterday. This is the first time something like this has happened. Luckily, (or so I thought) I have my Zosi security camera system! I thought it would be simple to find video of the perpetrator and report him to authorities. That assumption is where my nightmare began. The camera's "motion sensor" somehow picked up the delivery man leaving my property but it never triggered when he placed them at the door (he took a picture of the delivered packages at my door so I know they were there). When I arrived home I walked around the back of my property and the camera picked up me entering my house but not walking around the back. How could it miss something so obvious as a PERSON walking right in front of it? I spent an hour and a half re watching the footage at 1x speed (2x speed went way too fast to pick up anything and there was no in between option) to try to find who stole my items. You know what I saw? Trees moving in the wind. Nothing. This system's motion sensor will pick up a tree or nothing for fifteen minutes at a time but something as large as a person placing a package at a front door will not trigger it. Did I mention the sensor was sent to its most sensitive setting?...Yet still no footage of the brazen thief who stole these items in broad daylight. I also noticed other flaws with the system, such as I would view a car drive down the street and it would disappear midway through it. I am pretty disappointed with this system, the software was difficult to deal with too, especially when trying to scroll to a point in a video, it either did it or completely ignored my request. I called the cops and one of the first things they did when they arrived was point at the camera and say "that didn't pick it up?" I was so EMBARRASSED. No, no it did not pick it up (I do have some lovely footage of trees in the wind that it DID pick up though). I paid so much for this system and it was basically like having nothing at all. I now have no choice but to have it on "always record" because the motion sensor is so horribly unreliable. I have lost faith in Zosi and thought their product was higher quality than this.
