CCTV surveillance systems depend on stable connectivity for video transport, remote recorder access, and centralised monitoring. Connected IoT Limited provides industrial-grade 4G and 5G connectivity designed for dependable operation across fixed and temporary surveillance installations.
Surveillance systems must be isolated from general networks and managed without exposing recorder interfaces publicly. Typical capabilities include:
IP cameras connect to a local LAN or PoE switch with a network video recorder (NVR) or storage node. The LAN uplinks to an industrial cellular router with external antennas. The router enforces VLANs, QoS and firewall policies to separate video transport, telemetry and management traffic, and it terminates persistent TLS/IPsec VPN tunnels to a central gateway or video management server.
Video streams are forwarded from cameras through the recorder to the VMS over the VPN. Telemetry and health metrics are forwarded to monitoring systems, while management access is handled on a separate plane using certificate‑based authentication.
Adequate and consistent upload bandwidth is required for predictable video quality and retention schedules. Bitrate adaptation, GOP sizing and stream keepalives reduce the impact of transient network congestion. During short outages, recorders should buffer frames locally and resume streaming once connectivity returns. Recovery processes must include proper stream synchronisation and timestamp alignment to prevent gaps or duplicate frames in archived footage.
Fixed lines often involve longer lead times and can be subject to third‑party infrastructure that limits operator control or creates single points of failure. Site Wi‑Fi may be shared or lack bandwidth guarantees required for continuous video transport. Cellular allows operators to deploy independently of site infrastructure and implement operator diversity with dual‑SIM or multi‑operator eSIMs for resilience. While fixed lines can offer higher sustained throughput in ideal conditions, modern 4G and 5G networks provide adequate upload capacity and latency consistency for surveillance when designed with bitrate management and local buffering.
