How a 4G camera works

A 4G camera connects to the mobile network via a SIM card (just like your phone). It sends alerts and video directly to your phone via the internet โ€” no router, no WiFi, no cables needed. Pair it with a solar panel and it becomes completely autonomous.

The key question before buying

Check 4G coverage at the exact installation point before buying anything. Take your phone to the spot and verify you have at least 2โ€“3 bars of signal. Even 3G works for alerts and occasional viewing.

When to choose 4G vs WiFi

โœ…
Choose 4G if...

You're monitoring a farm, rural plot or country house without a router. The installation point is too far from your WiFi. You need the camera to work even if your home internet goes down.

โŒ
Don't choose 4G if...

You already have good WiFi coverage at the installation point. You want to avoid monthly SIM costs. You need continuous 24/7 recording โ€” 4G data costs make this expensive.

Frequently asked questions

Any Spanish operator works. Check which has the best coverage at your specific location. A 1โ€“3 GB monthly data plan is enough for alerts and occasional viewing. Cost: โ‚ฌ3โ€“8/month. IoT data SIMs (like Movistar M2M) can be even cheaper.
Not directly โ€” each 4G camera needs its own SIM. The alternative is to install a 4G router with a larger data SIM and connect conventional WiFi cameras to it. This is often more economical if you need 3+ cameras.
In motion detection mode (not continuous streaming), 3โ€“10 days without solar charging. With a larger external panel (6โ€“10W), this risk is minimised even in winter or cloudy regions.
