## Customer Reviews

### ⭐⭐⭐⭐⭐ Great investment
*by C***N on May 28, 2025*

Easy set up/connect to network. I didn’t want to drill holes into my door frame or siding so I just used some Velcro on the back of the bracket and it’s worked great. Love that I can see when my packages are delivered when I’m not home as well as any one else coming and going. Motion detection had been good.

### ⭐⭐⭐⭐⭐ Incredible Bargain: Security Camera That Exceeds Expectations with Top-Notch Performance
*by M***B on November 15, 2024*

The media could not be loaded. I’m honestly amazed at how much I got for the price of this security camera. After using it for a few weeks, it has far exceeded my expectations in terms of both performance and value. If you’re on the hunt for an affordable, reliable security camera that offers excellent features, this one is a steal.The setup took about an hour, mainly because I took my time to choose the ideal placement and get everything properly configured. The instructions were clear, and the process was fairly simple. Once everything was hooked up, the camera easily synced with the app, which has been user-friendly and reliable ever since.The video quality is fantastic—sharp, HD resolution that’s clear even in low-light conditions thanks to impressive night vision. I provided a video of the day and a photo of night vision. The motion detection is fast and accurate, with few false alerts so far as long as you tweak the sensitivity settings. Plus, I can get instant notifications when the camera detects movement, which is incredibly convenient.One of the features that really sets this camera apart is its battery-powered design, which means you can place it anywhere, free from the need for electrical outlets or complex wiring. I was able to install it in several spots around my property without worrying about cords, and it’s been working perfectly without the hassle of outlets or extension cords. The only issue I had was a line-of-sight issue from the hub. I had to play with which room I plugged the hub in to make sure it could speak to every camera. Basically, my fridge was causing signal problems when a line of sight had the fridge in between. The solution was painless just plugged it into different rooms until all cameras had a good connectionThe storage options are also worth noting. While the camera offers cloud storage, I appreciate that it doesn’t lock you into a subscription model. For those who prefer not to pay for cloud storage, you can use a USB drive to store your footage locally. This gives you flexibility and can save you money in the long run if you don’t want the ongoing fees for cloud storage. This is the route I went, my only irk was that the cloud service separates the videos in a more organized way. Where the USB has all cameras listed in one single group by day. So cloud service brings more premium access.The build quality is solid and weatherproof, which makes it ideal for outdoor use. I’ve had it up in rain and wind without any issues, and it continues to perform flawlessly. One camera was tilted by a squirrel but that's more of a "my house" problem than a blink problem.Other handy features include two-way audio, which is perfect for communicating with anyone at your door or even monitoring deliveries, and the app has been reliable for live streaming and playback.All things considered, this camera delivers premium features—like HD video, accurate motion detection, flexible battery placement, and local storage—at a price that’s hard to beat. If you’re looking for an affordable, no-fuss security solution, I highly recommend this one. It offers excellent value and performance, especially if you don’t want to be tied to cloud storage fees.

### ⭐⭐⭐⭐⭐ I love my cameras
*by R***3 on April 19, 2025*
