SIM Connectivity for
Security & CCTV Systems.

Keep your cameras online 24/7. Zentari provides high-bandwidth, fixed IP SIMs designed specifically for NVRs, IP cameras, and remote security hardware — with multi-network resilience and zero-overage billing built in.

The Problem We Solve

Security SIMs that don't drop when it matters most.

Single-network SIMs go offline. Overage bills surprise you at month end. Remote cameras are impossible to diagnose without a site visit. Zentari fixes all three.

Single Network = Single Point of Failure

If your CCTV SIM is locked to one carrier and that network has an outage or poor coverage at height, your footage stops recording. With Zentari, cameras roam across all four networks automatically.

Unpredictable Monthly Bills

HD camera feeds consume variable data. A single camera event — a busy weekend, a triggered alarm — can cause a usage spike. Our Watchdog rules auto-suspend before any overage is generated.

Costly Remote Diagnostics

Camera offline? Without a fixed IP and remote access, you're sending an engineer to site. Zentari gives every device a static IP and lets you reboot, test or reconfigure it from the Axis Portal.

Support remotely. Bill cleanly.

Zentari is built around the way security installers actually work. Order unactivated SIMs in bulk, ship them with your hardware, and activate each one from the Axis Portal the moment it goes in — you don't pay a penny until it's live.

Once deployed, every camera is remotely addressable via its fixed IP. Your NOC team can run diagnostics, reboot the connection, or check live usage without a single site visit.

Technical Specification

Everything your NVR needs.

Designed to meet the connectivity requirements of modern IP camera and NVR deployments.

Static Fixed IP Addresses

Static IP addresses enable direct access to your NVR or camera from your monitoring platform. Contact us to discuss fixed IP availability for your deployment.

VPN & Private APN

Route all camera traffic through your private network via L2TP or IPSec. Keep footage completely off the public internet.

High-Bandwidth 4G / 5G

Full 4G LTE and 5G throughput for HD and 4K camera streams. Prioritised data routing ensures footage quality isn't degraded during peak usage.

Usage Monitoring & Alerts

30-minute CDR polling means you see usage spikes almost in real time. Set email alerts or Watchdog rules to act before data runs out.

JIT Activation for Installers

Stock SIMs on the van. Activate each one only when it's installed. Zero monthly cost for inventory sitting in your warehouse.

Multi-Network Resilience

Cameras roam across all four UK networks. If one carrier has signal issues at the installation site, the device seamlessly connects to the next strongest.
