What to know before buying
Listing details to confirm
The listing is inconsistent about image specifications: it claims 2K video while separately labelling 5 MP as effective video resolution and 5 MP as still resolution. Treat 2K as the stated video resolution and confirm the exact recording specification if it matters. Its storage field says 128 GB, but the listing also says an SD card is not included and describes expandable local storage with HomeBase S380, so confirm what storage applies to your chosen setup. Continuous recording and five-second pre-roll are stated for hardwired use with a 16-24V, 30VA transformer and a bypassed existing chime. Battery use is described as rechargeable, but recording duration is not specified. Video calling is stated to work only in solo use, with HomeBase S380 support described as expected later. The listing also claims both motion-only alerts and human detection, so alert behaviour is not fully clear.
Who is it for?
A good fit for
- Buyers seeking a doorbell camera with 2K-listed video and battery or wired power choices.
- Homes with compatible wiring that can meet the stated transformer requirements and bypass the existing chime for continuous recording.
- Buyers who want HomeBase S380 compatibility and are willing to check which features work with their chosen setup.
Less suited to
- Buyers who need confirmed battery runtime or consistently reliable connectivity based on the available customer feedback.
- Buyers who require uninterrupted recording while using battery power.
- Buyers who need video calling while connected to HomeBase S380, based on the listing's stated solo-use limitation.
