Wireless security camera EZVIZ CH1 White — 2.4 GHz Wi‑Fi (802.11b/g/n), 100–240V AC, 20 melodies, speaker, 72 dB

The EZVIZ CH1 Smart Wi‑Fi Chime is an indoor wireless chime designed to work with EZVIZ battery-powered video doorbells (such as EP3x Pro and compatible models). It provides audible notifications when the doorbell is pressed and helps extend and stabilize the 2.4 GHz Wi‑Fi connection between an outdoor battery doorbell and your home network while optimizing the doorbell’s battery use. The compact AC‑powered device includes a built‑in speaker, indication light and a reset button.

Advantages

The CH1 improves signal reliability for battery-powered EZVIZ doorbells located far from the router, reducing missed alerts and ensuring more consistent two‑way communication. It produces clear audible alerts up to 72 dB at 1 meter and offers up to 20 selectable ringtones, adjustable volume and a mute option for quiet periods. Installation is simple and the unit runs from standard AC power, suitable for continuous indoor use.

Suitable for

• Homes where an outdoor battery doorbell is located far from the Wi‑Fi router
• Users who want audible in‑home notifications independent of smartphone reachability
• Households that need selectable ringtones and adjustable volume for doorbell alerts

How to use

Plug the CH1 into an indoor AC socket within range of your home Wi‑Fi network and follow the EZVIZ app or quick start instructions to add the chime to the same account as your EZVIZ battery doorbell. Choose a ringtone and set the desired volume or mute the chime for private hours. The CH1 will receive signals from the paired doorbell and play the selected ringtone whenever the doorbell is pressed.

Usage recommendations

Place the chime in a central indoor location free from large metal obstructions for best audio coverage and Wi‑Fi signal boosting. Avoid placing the CH1 near other devices that heavily use 2.4 GHz Wi‑Fi to reduce interference. Use the mute setting during nighttime or quiet periods as needed.
