Ezviz 4G Sim 2K Indoor Battery Camera with Power bank -CB2 4G Kit
The EZVIZ CB2 4G Kit combines the palm-sized CB2 4G indoor camera with the EZVIZ Power Partner battery pack. The camera connects through a nano SIM card on the 4G network instead of Wi-Fi and records in 2K (3MP), while the 2,000 mAh camera battery and the 5,200 mAh Power Partner give a total of 7,200 mAh, so it can work without Wi-Fi or a power outlet.


4G connection, no Wi-Fi needed: Insert a nano SIM card with a data plan and the camera sends live video and alerts over 4G. This makes it useful in a holiday home, garage, caravan or any indoor space without internet.
Power Partner for longer battery life: The included Power Partner is a 5,200 mAh battery pack made to work with the CB2 4G. Placed next to the camera, it keeps the camera charged, so you need to recharge far less often than with the camera's own battery alone.
2K picture and human detection: The 3MP camera records in 2K resolution. An AI chip together with a PIR sensor detects human shapes, so you are alerted when people appear rather than for every movement.
Two-way talk: A built-in microphone and speaker let you see, hear and talk through the camera from your phone.
Time-lapse and easy placement: A physical time-lapse button lets the camera produce fast-forward videos (a microSD card is required). The magnetic base lets you stand the camera on a flat surface or attach it to metal.
Storage and voice assistants: Recordings can be saved on a microSD card of up to 512 GB (not included) or in EZVIZ CloudPlay with a subscription. The camera also works with Amazon Alexa and Google Assistant for live view on a smart display.
Good to know
The camera does not support Wi-Fi; a nano SIM card and a cellular data plan are required and are not included. The microSD card is sold separately.
