Why do some customers return this product?
Most returns are due to compatibility or usage misunderstandings, not product quality. This device supports 2.4 GHz Wi-Fi only (no 5 GHz). Some customers purchase by mistake or find their home Wi-Fi signal or installation environment not suitable.
Why does it show a network connection failure?
1. The Boifun video doorbell only supports 2.4GHz Wi-Fi and cannot connect to 5GHz Wi-Fi. Please try switching your network.
2. Weak Wi-Fi signal due to distance. Install the doorbell closer to your Wi-Fi router.

1. Double-sided adhesive – Suitable for smooth, flat surfaces like doors or walls.
2. Wall-mounted with screws – Ideal for rough or uneven walls.
Note: Accessories included. Check black box.
How to improve the battery life performance?
1. Set the recording time to normally 10-20s which is enough for daily needs.
2. Lower down the "Motion Detection" sensitivity or open the "Human Motion Detection" function.
3. Adjust the angle of the doorbell to avoid unnecessary activation.
