Frequently Asked Questions
Does this camera work while mounted inside behind a window?
Yes, it is designed for indoor window-facing placement and uses AI anti-glare technology to reduce the reflections that normally interfere with filming through glass.
How long does the battery last before it needs recharging?
BestDay rates the rechargeable battery at up to 45 days per charge, though heavy motion-triggered recording will shorten that real-world figure.
Do I need a paid subscription to store recordings?
No. You can record to a local MicroSD card up to 128GB, or use cloud storage, and BestDay states there is no mandatory subscription for the cloud option.
Will it constantly alert me for cars and pets?
No. Its AI human detection is built to distinguish people from vehicles, animals, and shadows, and you can set custom motion zones and schedules to further reduce false alerts.
Is a memory card included in the box?
No, the MicroSD card is not included. The camera supports cards up to 128GB if you want local storage instead of, or alongside, cloud.
Does it connect to 5GHz WiFi or only 2.4GHz?
Both. The camera supports dual-band 2.4GHz and 5GHz WiFi for more stable, faster video streaming.
