Why Use a 4G Router for CCTV?
Running CCTV cameras in locations without fixed-line internet — a remote property, construction site, farm, shop, or gate — is one of the most practical uses for an outdoor 4G router in Sri Lanka. A single router can power multiple IP cameras wirelessly, with footage accessible from your phone anywhere in the country.
This guide walks you through exactly how to set it up.
What You'll Need
- An outdoor 4G router (weatherproof, IP65 or higher)
- A data SIM card with a suitable data plan (Dialog, Mobitel, or Hutch recommended)
- IP cameras (wired PoE or wireless Wi-Fi cameras)
- A PoE switch (if using wired cameras)
- Ethernet cable (Cat 5e or Cat 6) for wired connections
- A mounting pole or bracket
- Optional: solar panel + battery if mains power is unavailable
Step 1: Choose the Right Location for the Router
Mount the router at the highest practical point — rooftop, pole, or wall — where it has a clear line of sight toward the nearest cell tower. Use a signal app (Network Cell Info or similar) to identify the tower direction before drilling any holes.
The router should also be central to your camera positions to maximise Wi-Fi coverage, or you can run Ethernet from the router to a PoE switch closer to the cameras.
Step 2: Install the SIM Card and Power Up
- Insert your data SIM into the router's SIM slot.
- Connect the router to power — most outdoor routers use a PoE injector (power over Ethernet) so you only need to run one cable from indoors.
- Wait for the router to boot and connect to the 4G network (usually 1–2 minutes).
- Check the signal indicator — aim for at least 3 bars before proceeding.
Step 3: Configure the Router
- Connect your laptop or phone to the router's Wi-Fi network (default credentials are on the label).
- Open the router's admin panel (typically 192.168.1.1 in your browser).
- Set your APN to match your SIM operator:
- Dialog:
dialog.broadband - Mobitel:
mobitel.lk - Hutch:
hutch.lk
- Dialog:
- Change the default Wi-Fi password to something strong.
- If signal is marginal, enable band locking and fix to Band 3 (1800 MHz) for Dialog or the strongest band for your operator.
Step 4: Connect Your CCTV Cameras
For Wi-Fi cameras: Connect each camera to the router's Wi-Fi network using the camera's app or web interface. Keep cameras within 20–30 metres of the router for reliable signal.
For wired PoE cameras: Run Ethernet cable from the router's LAN port to a PoE switch, then connect each camera to the switch. This is more reliable and supports longer cable runs (up to 100 metres per segment).
Step 5: Set Up Remote Viewing
Most modern IP cameras and NVRs support P2P cloud viewing via a mobile app (e.g., Hik-Connect, DMSS, or the camera brand's own app). Simply scan the QR code on the camera or NVR, and you can view live footage from anywhere on your phone — as long as the router has a 4G connection.
For more advanced setups, configure DDNS in the router's admin panel to get a fixed address for your cameras, enabling direct access without relying on a cloud service.
Step 6: Optimise for Reliability
- Set a data usage alert in the router admin to avoid unexpected bill shock if cameras record continuously.
- Enable auto-reboot (scheduled daily restart) to keep the router fresh and avoid memory issues over time.
- Use motion-triggered recording on cameras to reduce data consumption significantly.
- Check signal monthly — vegetation growth or new buildings can affect signal over time.
