How this review was made: We did not test this product in person. This verdict is based on our analysis of expert reviews and owner themes, all listed at the end of this article. Evidence on long-term durability is mostly secondhand, and we say so below. Our method.
A strong, simple pick for a basic indoor camera
Reviewers describe the C120 as a bargain: sharp 2K video, responsive motion alerts, people and pet detection, two-way audio and quick app setup, with recordings that can go to a microSD card instead of a mandatory cloud plan. The trade-offs are a fixed view, black-and-white night vision, 2.4 GHz Wi-Fi only, a one to two second lag on live talk, and no card in the box.

How it holds up over time
We found no rigorous long-term test of the C120. Smart Home Compared says owners report durability, but it summarizes feedback secondhand, and it mentions the microphone may degrade with long, harsh use. Treat durability as likely good but unproven.
Tips from owners
- Buy a card of 128 GB or less,since larger cards are not supported.
- Use the 2.4 GHz network,as the camera does not use 5 GHz.
- Set activity zonesin the app to cut unwanted alerts.
