What SIM and data plan do I need?

Any UK SIM works — EE, Vodafone, O2 or Three. Most 4G cameras are unlocked, so you can bring your own data plan or buy a pre-configured SIM from us. For the best rural coverage, EE is typically strongest, while Three offers good value unlimited plans for sites that use a lot of data.

Expect to use 10–50 GB per month depending on resolution and how often the camera records. Continuous recording at 4MP uses more data than motion-triggered 2MP clips. Some cameras support dual-SIM setups, so if one network drops out, the camera automatically switches to the backup SIM for uninterrupted coverage.

Frequently asked questions

What resolution do I actually need?

For general surveillance, 2MP (1080p) is sufficient. For identifying faces or plates at distance, 4MP or 8MP with optical zoom is recommended.

Which UK network is best for CCTV?

EE has the widest 4G coverage, especially in rural areas. Three offers good value unlimited data plans. We test coverage at your location before recommending.

How much does a good 4G camera cost?

Entry-level 4G cameras start at £80–120. Mid-range with PTZ and AI: £200–400. Premium solar PTZ systems: £500–1,000+.

Can I use my existing SIM card?

Yes, most 4G cameras accept any unlocked UK SIM. You can bring your own data plan or buy a pre-configured SIM from us with the right data allowance already set up.

Do I need planning permission to install a 4G camera?

Generally no for domestic use, but check with your local council if the camera overlooks public areas or if your property is listed. Commercial sites rarely need permission for security cameras.

How long does installation take?

Most 4G cameras are up and running in under an hour. Solar models take a bit longer to position the panel correctly, but still typically under two hours for a complete setup.

What happens if the camera gets vandalised?

Look for cameras with a high weatherproof rating and metal housings. Many models send instant alerts if they're moved or disconnected, and footage is usually already saved to the cloud or SD card before damage occurs.
