4G security cameras are becoming one of the most popular CCTV options in the UK - especially for locations where broadband simply isn’t available. Whether you need to monitor a remote farm, track activity around a holiday home, protect a construction site, or secure a detached garage, 4G SIM card CCTV cameras offer the perfect blend of flexibility, reliability and on-demand access.
Unlike standard Wi-Fi or wired systems, 4G CCTV connects using mobile networks (EE, Vodafone, O2), giving you live video, alerts and recordings from virtually anywhere.
In this guide, we’ll cover the best 4G CCTV options, the equipment you actually need, and how to build a fully remote CCTV system using TP-Link solutions from WME. We’ll also show how you can pair this with smart access control, like the new WME DL2 Smart Lock, to create a complete security package for off-grid properties.
What Are 4G SIM Card Security Cameras?
A 4G security camera uses a SIM card to connect to the internet, instead of relying on home broadband or wired networks.
This makes them perfect for:
- Rural homes
- Farms & agricultural sites
- Remote garages & outbuildings
- Construction sites
- Vacant properties
- Car parks & vehicle storage
- Holiday homes & caravans
- Locations with no Wi-Fi or landline
Because they use mobile data, you get full remote access regardless of location - simply open the app on your phone to view footage in real-time.
How 4G CCTV Cameras Work (Simple Breakdown)
To build a 4G CCTV system, you need:
✔ A 4G-capable NVR
WME stocks Hikvision 4G NVRs that work with any UK SIM card.
These create a local Wi-Fi network your camera connects to.
➡️ Browse All NVRs
✔ A compatible wireless outdoor camera
These cameras connect to the router just like standard Wi-Fi cameras.
Most TP-Link and Hikvision Wi-Fi cameras work perfectly in 4G setups.
✔ A SIM card with a suitable data plan
You’ll need:
- 10–20GB per month for standard use
- 30–60GB for heavy recording or multi-camera setups
✔ Optional: A smart lock or security alarm
Useful for remote sites that you want to control with your phone.
The new WME DL2 Smart Lock is ideal for holiday properties, rentals, or gated storage units.
