This guide is for anyone whose EZVIZ battery camera, battery doorbell or door viewer won’t charge or runs flat too quickly. The steps follow EZVIZ’s guide to a camera that can’t be charged and its battery-drain FAQ, in EZVIZ’s order.

What This Problem Means

EZVIZ’s charging fixes are about the power source, the cable and the temperature. Its battery-drain fixes are about the Wi-Fi signal, power-saving modes and detection settings. If you charge from a solar panel, see how to fix an EZVIZ solar panel that isn’t charging.

Common Symptoms

• The battery level doesn’t go up when the camera is plugged in
• The charging light doesn’t come on (each model’s light is in the table below)
• The battery runs down much faster than expected
• Charging stops in very hot or very cold weather

Safe Checks You Can Try

1. Check the power socket

Make sure the power outlet you’re using works properly. EZVIZ also suggests plugging the camera into a different outlet.

2. Check the cable

Make sure the power cable isn’t damaged or frayed, and try a different charging cable to see if that solves it.

3. Charge at the right temperature

EZVIZ’s charging guide says the temperature for battery charging should stay between 0°C and 45°C. The CB1, BC2, BC1C, CB8 and CP4 manuals say the same; the HP3 Pro manual gives 0°C to 50°C.

EZVIZ’s BC2 support page notes that you may need to charge more often below 0°C. The CB8 manual adds: “It is not allowed to charge the camera with power adapter outdoors.”

4. Use the adapter EZVIZ lists

EZVIZ’s manuals and pages give a 5V 2A adapter for most of these models, but 5V 1A for the CB1 and CB2, and several don’t include one in the box. The table below shows each model. On the CP4, EZVIZ’s manual says: “Do not charge through the interface at the bottom.”

5. If it still has some charge, try a reset

EZVIZ’s charging FAQ says that if the camera still has some charge, you can try a reset by holding the reset button for about 10 seconds. Model manuals give shorter holds, so check how to reset an EZVIZ camera. A reset restores the default settings.

6. Draining fast: check the Wi-Fi signal

If the battery runs down quickly, EZVIZ’s first check is that the network connection is good, with no barrier or radio interference.

7. Turn on a power-saving mode

EZVIZ suggests turning on Power Saving or Super Power Saving mode. In those modes, EZVIZ says only active live view can wake the camera.

8. Lower the detection sensitivity and draw detection areas

EZVIZ also suggests lowering the detection sensitivity and drawing detection areas, both in camera Settings > Intelligent Detection. If the camera still won’t charge after these steps, EZVIZ says to contact its support team.

Battery and Charging by Model

The charging lights come from EZVIZ’s manuals. On the CB1, EZVIZ says fast-flashing red can also mean “Battery low”. The CB1 manual says a full charge takes about 4.5 hours, and the HP3 Pro manual says about 4.5 hours with a 5V 2A adapter.

When To Contact Support

If none of these steps fix it, contact EZVIZ through EZVIZ’s support site.
