Hvordan fungerer et 4G SIM-kamera uten WiFi?

A 4G SIM camera can work without WiFi because it connects through a cellular LTE network instead of a local wireless router. With a compatible SIM card, power and mobile coverage, supported models can send video and alerts through the mobile network.

How a 4G SIM Camera Connects

The connection path is: camera → SIM card → 4G/LTE network → internet → app or remote viewer. A true 4G camera does not need a WiFi router for this connection.

What Do You Need?

• A 4G/LTE camera or module
• Compatible SIM and mobile data
• 4G coverage
• Suitable power
• The supported app or software

Does It Need a Data Plan?

Normally yes. Live viewing, alerts and internet-based functions use mobile data. Continuous streaming generally consumes far more data than occasional checking.

Does It Still Need Power?

Yes. 4G describes connectivity, not power. Some cameras use batteries or solar charging, while many modules require continuous DC power.

Can It Record Without Mobile Data?

Some models can record locally to microSD/TF storage even if remote connectivity is unavailable. This is model dependent.

What Should You Check?

Check regional cellular bands, SIM compatibility, resolution, lens, night vision, storage, app, power and features such as audio or ONVIF.
