EZVIZ CB3 4G Battery Security Camera 5200mAh
Product description
This outdoor battery camera from EZVIZ combines 4G connectivity and 2K recording to keep remote sites under watch without fixed broadband. It suits gardens, rural properties or temporary installs where Wi‑Fi is absent, and it prioritises long runtime and clear night imaging.
What matters most
The CB3 offers up to 90 days of operation on a single charge according to EZVIZ lab tests, based on modest daily use, so you get extended periods between charges. If you prioritise lasting battery life over mains power, this camera reduces the need for frequent maintenance, and if you prefer continuous coverage you can enable Always‑On Video for 24/7 recording when required.
Technical details

Why it makes sense
The unit supports local storage up to 512GB via microSD, which avoids ongoing subscription costs when you prefer to keep footage locally. It also includes AI human detection to reduce false alerts, two‑way audio for remote communication and a built‑in siren to deter intruders. Note that Wi‑Fi is not supported and a nano SIM card is required for network features, UK carriers supported include O2, Three and Vodafone according to the manufacturer.
Best use cases
It suits you if you need a truly wireless camera that can be installed away from a house or where broadband is unreliable, and you value extended battery life plus clear night recordings. It may not suit you if you require constant cloud backup without inserting a SIM or if you need seamless Wi‑Fi integration at all times.
What you get
The package is aimed at straightforward outdoor surveillance, offering monitoring, two‑way talk and deterrent functions in one weatherproof unit. Solar panel compatibility is included for those who want to extend runtime further. The camera integrates with Alexa and Google for basic voice control according to the product listing.
