QHD WiFi Security Camera System Outdoor
Emily M.
Ottawa, ON
June 14, 2025
As a teacher who values safety and is a bit cautious with tech, I bought this as a gift for my home after some research. It seems quite effective overall, but it's not without its quirks. The courier called ahead for delivery, which was nice. I like that I can see everything clearly and talk through the camera, but the setup process was a headache—definitely not plug-and-play. After a week or so of use, I've gotten used to it, and it does make me feel more secure, though I wish the smart features were a bit smarter. For the price, it's a decent choice, but I'd recommend it with the caveat that you might need to tweak things to get it just right :)
- Pros: The video quality is quite sharp, making it easy to see details even from a distance. I appreciate that it works well in low light, capturing colors instead of just shadows, which is a big plus for nighttime monitoring. The two-way audio is handy for communicating with visitors without opening the door, and the weather resistance means it holds up fine in Ottawa's unpredictable weather. Remote access through the app is reliable, allowing me to check in from anywhere, which feels reassuring.
- Cons: Setting it up took some time and a bit of fiddling with the app, which was frustrating at first. The siren feature, while useful, can be a bit loud and might startle me if it goes off unexpectedly. After adjusting settings, I noticed that the human detection isn't perfect—it sometimes picks up animals or moving branches, leading to false alerts. The storage fills up quickly, and managing recordings requires regular attention to avoid losing important footage.
