Overview

The EZVIZ CB5 4K is a battery camera with a solar panel built in. EZVIZ’s UK page lists 4K (3840 x 2160) video at 15fps from a 1/2.7in 8MP sensor, and a 2.8mm F1.6 lens with a 135° diagonal and 113° horizontal view. Infrared and colour night vision both reach 15 m. It has AI human shape and vehicle detection, and EZVIZ says that with AOV mode enabled it can detect movement up to 25 m away by day and 12 m at night. When it detects intruders, EZVIZ says it sounds a siren and flashes two spotlights, and two-way audio is supported.

Power comes from a 10,400mAh battery, which EZVIZ says lasts up to 180 days without solar charging in its lab tests, based on 5 minutes of use a day, and the built-in 1.4W panel, which EZVIZ says needs 2 hours of charging for a whole day’s use; it adds that actual charging efficiency depends on sunlight and other conditions. It also works with EZVIZ add-on solar panels that use Type-C cables, and charges at DC 5V 2A with the adapter sold separately. Storage is microSD up to 512GB or EZVIZ cloud storage. It connects over 2.4GHz Wi-Fi, supports Bluetooth and is rated IP65. EZVIZ lists Google Assistant and Amazon Alexa.

Setup & Installation

These are EZVIZ’s general add-device steps. Download the EZVIZ app, register an EZVIZ account with your email or phone number and log in. Reset the camera, then wait about a minute until the light flashes red and blue alternately or blue quickly; EZVIZ says some cameras show no light change, so just wait. Connect your phone to 2.4GHz Wi-Fi only, tap + on the app’s home page, scan the QR code on the device label (usually on the back or bottom) and follow the instructions in the app to connect it to your Wi-Fi.

If the app asks for a verification code, EZVIZ says it is normally printed on the device label.
