Router Wi-Fi Configuration Requirement for CCTV Remote Access
To ensure stable CCTV connectivity, reliable mobile access, and reduced network conflicts, the router must be configured to broadcast 2.4 GHz and 5 GHz as two separate Wi-Fi networks (separate SSIDs).
Mandatory Configuration
- Configure 2.4 GHz SSID and 5 GHz SSID as independent networks
- Each frequency band must be manually configured
- Both networks must remain separate at all times
Do NOT Enable or Use:
- Band steering
- Smart Connect
- Combined / unified SSID
- Auto, adaptive, or AI Wi-Fi modes
These features often cause IP conflicts, unstable CCTV connections, offline cameras, and mobile viewing failures, especially for NVRs, IP cameras, and IoT security devices.
Why This Is Important for CCTV Systems
- Most CCTV NVRs and IP cameras are optimised for stable 2.4 GHz connections
- Auto or smart Wi-Fi modes may force devices to switch bands, causing random disconnections
- Separate SSIDs provide predictable routing, consistent IP assignment, and reliable remote access
- Reduces troubleshooting time and long-term system instability
Recommended Best Practice
- Connect CCTV NVRs and cameras via LAN cable whenever possible
- Use 2.4 GHz Wi-Fi only if wiring is not feasible
- Reserve 5 GHz Wi-Fi for mobile devices and high-speed user traffic

- Router reboot or replacement
- IP address changes by the ISP
- Weak Wi-Fi signal at the NVR location
Solution:
- Check if your internet is working normally
- Restart the router and NVR
- Use a wired LAN connection for NVR instead of Wi-Fi
- Ensure stable bandwidth, especially for HD cameras
2. CCTV App or Cloud Service Issues
Common Problems:

- Wrong login credentials
- Device removed from cloud account
- Cloud server maintenance or changes
Solution:
- Update your CCTV mobile app
- Re-login and verify the correct account
- Re-add the NVR or camera using QR code
- Check if the brand’s cloud service is online
3. Port Forwarding or P2P Configuration Errors
Common Problems:
- Port forwarding not set correctly
- P2P (cloud) status showing Offline
- Router firewall blocking CCTV traffic
- Double NAT from multiple routers
Solution:
- Verify P2P status on the NVR
- Avoid complex port forwarding where possible
- Check router firewall and NAT settings
- Use professional configuration to prevent exposure risks

4. Router or Network Changes
Common Problems:
- Telco technician replaced the router
- Router factory reset
- Wi-Fi SSID or password changed
- New mesh or extender installed
Solution:
- Reconfigure CCTV network settings
- Assign static IP addresses where required
- Ensure the NVR is connected to the main router
- Avoid multiple NAT layers
5. Firmware or Software Compatibility Issues
Common Problems:
- Outdated camera or NVR firmware
- App no longer compatible with old firmware
- Brand security updates disabling old protocols
Solution:
- Update firmware on NVR and cameras
- Ensure app version matches system firmware
- Upgrade outdated CCTV hardware if required
6. Power or Hardware Faults
Common Problems:
- NVR or camera power adaptor failure
- PoE switch issues
- Overheating or damaged components
Solution:
- Check power supply and PoE ports
- Inspect cables and connectors
- Replace faulty power or network components
7. ISP or Public IP Restrictions in Singapore
Some ISPs restrict certain ports or use Carrier-Grade NAT (CGNAT), which can affect remote CCTV viewing.
Solution:
- Use P2P cloud access
- Consider a 5G / 4G industrial router
- Configure VPN-based remote access for secure viewing
When Should You Call a Professional?
If your CCTV:
- Shows offline on the app
- Works locally but not on mobile data
- Disconnects frequently
- Was working previously and suddenly stopped
It is best to engage a professional CCTV technician to avoid security risks or misconfiguration.
