What you need: Teltonika 4G router (RUT901 recommended), fixed IP SIM card with APN details, Ethernet cable, laptop or phone for configuration. Estimated setup time: 20-45 minutes.
Step 1: Get Your Equipment
You need three things: a 4G router, a fixed IP SIM card, and an Ethernet cable. The router connects to your NVR or PoE switch. The SIM card provides the 4G internet connection with a fixed, public IP address.
For most CCTV installations, we recommend the Teltonika RUT901 and a Millbeck M-Connect fixed IP SIM card. Both are available from Routerstore.com.
Step 2: Insert the SIM Card
Power off the router. Insert the fixed IP SIM into SIM slot 1. On the Teltonika RUT901 and RUTX11, the SIM tray or slot is on the base of the device. Slot 1 is the primary slot. If you have a backup SIM, insert it in slot 2.
Step 3: Connect the Hardware
Connect the router to a 12V DC power supply or the supplied power adaptor. Connect an Ethernet cable from one of the router's LAN ports to the WAN/Internet port of your NVR, or to an Ethernet switch that your NVR connects to. Screw the supplied 4G blade antennas onto the router SMA connectors - MAIN first, then AUX.
Antenna placement: The router should be positioned with clear line-of-sight to outside, away from metal enclosures and interference sources. If the router must go inside a steel cabinet, use an external antenna on a short coax cable (SMA extension) routed outside the cabinet.
Step 4: Log Into the Router
Connect a laptop or phone to the router via WiFi. The default WiFi SSID and password are printed on the label on the base of the router. Open a browser and go to http://192.168.1.1. Default login credentials are on the same label (typically admin / admin01 for Teltonika).
Step 5: Configure the APN
On a Teltonika router, go to Network → Mobile. In the SIM 1 configuration, set the APN to the value provided with your fixed IP SIM card. Leave authentication type as PAP/CHAP unless your SIM provider specifies otherwise. Click Save and Apply.
The router will connect to the 4G network. This may take 30-60 seconds. The mobile status indicator should go green.
Step 6: Verify Your Fixed IP Address
Go to the router overview or status page. Under the Mobile section, look for the WAN IP address. This should be a public IP address - not a 10.x.x.x or 192.168.x.x address, which would indicate a private IP (the wrong kind of SIM). If you see a public IP, your fixed IP SIM is working correctly.
Step 7: Set Your NVR LAN IP
Your router's LAN is typically 192.168.1.x. Your NVR needs a static LAN IP address in this subnet so port forwarding targets a consistent address. Log into your NVR and set its IP address to something like 192.168.1.100, subnet 255.255.255.0, gateway 192.168.1.1 (the router). Note this IP - you'll need it for port forwarding.
Step 8: Configure Port Forwarding
In Teltonika RutOS, go to Network → Firewall → Port Forwards. Create a new rule:
- Name: NVR Remote Access
- Protocol: TCP (or TCP+UDP - check your NVR documentation)
- External Port: The port your NVR uses for remote access (common: 8000 for Hikvision, 8080 for web, 554 for RTSP)
- Internal IP: Your NVR's LAN IP (e.g. 192.168.1.100)
- Internal Port: Same as the external port
Add multiple port forward rules for each service port your NVR uses. Hikvision NVRs typically need port 8000 (SDK), 8080 (web), and 554 (RTSP).
Step 9: Enable Ping Reboot (Cell ICMP Check)
This is the most important self-healing feature. 4G networks can drop connections on busy masts. Without Ping Reboot, you might lose access for hours without knowing. With it, the router checks connectivity every 60 seconds and reboots the mobile connection if it fails.
In Teltonika RutOS, go to Network → Mobile → Cell ICMP Check. Enable it. Set the host to ping as 8.8.8.8 (Google DNS). Set the interval to 60 seconds and the failure count to 3 (router will reboot connection after 3 consecutive failures). Save and apply.
Step 10: Test Remote Access
Take your phone off the router's WiFi and connect to a 4G network (your own mobile data, not the router's SIM). Open your NVR mobile app or browser. Enter the fixed IP address of the router and the port you configured. You should be prompted for your NVR login credentials and then see your cameras.
If it doesn't work, check: correct port in the URL, port forwarding rule is enabled, NVR IP matches the forwarding rule, and the NVR's own firewall isn't blocking the connection.
Security: A fixed, public IP address means your router is directly reachable from the internet. Change all default passwords on both the router and the NVR before enabling remote access. Enable the router firewall. Restrict remote admin access to specific IP addresses if possible. Enable HTTPS on your NVR.
