The real situation: farm without WiFi or electricity

You have a farm, plot or country house and want to see what's happening from your phone. The problem is clear: no WiFi router and no accessible power outlet. The good news is that technology exists designed exactly for this, requiring no works, cables or technicians.

What you need to understand before buying

A 4G solar camera works completely autonomously. It has its own connection (SIM card, like a mobile phone), its own power (solar panel + battery) and its own storage (microSD card). It doesn't depend on your home network at all.

The 4 components of the system

1. The 4G camera

This is the central element. It must have a nano SIM slot and support for 4G/LTE bands. There are fixed models and PTZ (with 355Β° rotation). For a farm, models with colour night vision and person detection (not just motion) are most useful.

2. The SIM card

Any Spanish operator works. The important thing is to verify that there is 4G coverage at the exact installation point before buying. A 1–3 GB monthly plan is sufficient for alerts and occasional viewing. Estimated cost: €3–8/month.

3. The solar panel

Many 4G cameras already include a small integrated panel. For areas with many hours of sunlight, it's usually enough. For areas with partial shade or cloudy winters, an additional 5–10W external panel greatly improves autonomy.

4. The microSD card

Allows local recording without depending on cloud services. A 128 GB class 10 microSD (SanDisk, Samsung) stores between 15 and 30 days of detected events. When full, it automatically overwrites the oldest files.

How to install the camera step by step

  1. Choose the installation point: 2.5–3 metres high, facing the main access area. Avoid shaded areas during peak daylight hours.
  2. Insert the SIM: open the camera slot and insert the nano SIM. Most cameras have a setup app that guides you through the process.
  3. Orient the solar panel: point south, tilted between 30Β° and 45Β°. No shadows.
  4. Set up the app: download the manufacturer's app, scan the camera QR code and follow the linking steps.
  5. Adjust detection zones: define in the app which areas of the frame trigger alerts to reduce false alarms.
  6. Place the video surveillance sign: legally required if the camera can capture public spaces or neighbouring properties.

Frequently asked questions

Yes. Most 4G cameras are compatible with 3G although with lower speed. Alerts and live video work, although real-time streaming quality may be lower. For local microSD recording, coverage doesn't matter.
The only monthly cost is the SIM card: between €3 and €8/month with a 1–3 GB plan. If you choose cloud storage, add €5–10/month, although with a microSD you can completely avoid that cost.
Depends on the battery and usage. In motion detection mode (without continuous streaming), between 3 and 10 days without sun. With a higher power external panel (6–10W), this risk is minimised even on cloudy days.
