Pros and cons
Pros
- Two CX820 cameras are identified in the built-in media list.
- Ethernet PoE avoids a separate data cable, and the listing supports microSD storage up to 512GB as well as NVR HDD and FTP recording.
- Warm lights offer Auto, Smart, Off and Timer modes, allowing different lighting behaviour to be selected.
- Detection covers people, vehicles and animals, with customisable light and siren alerts.
Cons
- A power adapter is explicitly not included, so the stated PoE/DC 12V power options require the buyer to arrange a suitable power source.

Customer feedback highlights picture quality, functionality, ease of setup and colour at night, and mentions compatibility with Scrypted NVR and Frigate. Low-light performance is mixed, with some finding the night lighting weaker than expected. That caveat matters for dark areas where the listed warm lights provide illumination. Aggregate ratings skew towards five-star responses, but do not establish how the cameras perform in a particular installation.

- Customers report clear night vision and pleasing colour at night.
- Compatibility with Scrypted NVR and Frigate is noted in customer feedback.
Mixed feedback
