CCTV & IP cameras

IoT connectivity for video surveillance

4G/5G SIMs with static IP for IP cameras, NVRs and CCTV systems across construction sites, parking lots, retail chains and remote locations. Continuous streaming and remote access without relying on fixed lines.

Key features

Standard IP cameras

Works with Hikvision, Dahua, Axis, Bosch and Hanwha over RTSP, ONVIF or HTTPS.

4G / 5G streaming

Enough bandwidth for 1080p and 4K with H.265. Multi-carrier so mobile sites never lose signal.

Static IP for NVR

Dedicated public address to reach the recorder directly — no NAT, no intermediaries.

Cloud VMS

Integration with cloud platforms (Eagle Eye, Milestone, Genetec) for video surveillance as a service.

Alerts & backup

Event-driven clip upload (motion, intrusion) and cloud backup so you don't depend on local storage.

GDPR-ready

End-to-end encrypted traffic over private APN. Access logs for audit trails.

Use cases

Construction sites
Outdoor parkings
Multi-site retail
Farms and ranches
Solar plants and remote substations
Temporary event security

Typical problems

  • Cameras at construction sites or temporary locations with no fixed line — the customer wants remote NVR access but the single operator doesn't cover the spot.
  • 1080p H.264/24fps streaming saturates a standard data plan in days — bill surprise the first month.
  • NVR behind operator CGNAT, impossible to SSH/HTTPS from outside without DDNS or intermediate services.
  • Physical NVR theft on construction sites — if storage is local-only, all incident recordings are lost.
  • Hikvision/Dahua cameras and NVRs exposed directly to the Internet with known CVEs that get exploited within hours.
  • Lack of GDPR compliance for cameras recording publicly accessible spaces — incomplete signage or missing DPIA.

Recommended architecture

  1. 1

    Industrial 4G/5G router with multi-operator SIM as the NVR's WAN

    The NVR (Hikvision DS-7600, Dahua NVR4, Axis S3008) connects to the router via Ethernet. The router manages the SIM and picks the best available operator. Multi-WAN with failover if more than one connectivity is available.

  2. 2

    Static public IP over SIM for NVR remote access

    Without static IP you need DDNS or proprietary cloud services. With static IP + SIM-level firewall (ACLs) you open SSH/HTTPS only to your IT team and block the rest of the Internet — drastically reducing the attack surface.

  3. 3

    Private APN with IPsec encryption to cloud VMS

    Streaming tunnels to the VMS (Eagle Eye, Milestone XProtect, Genetec Security Center). Never the public Internet. GDPR-compliant for personal data (identifiable faces, license plates) with mandatory network segmentation.

  4. 4

    Generous per-camera data plan or single backhaul per NVR

    A 1080p H.265 camera at continuous 15fps uses 50-150 GB/month. NOT viable per-SIM individually. The realistic architecture is: NVR centralizes streams → 4G/5G backhaul transmits ONLY event clips + thumbnails + on-demand access. Drops consumption to 1-10 GB/month depending on event frequency.

Indicative data plan

DeviceTypical monthly trafficRecommended plan
NVR + 4-8 IP cameras, event-only transmission1-5 GB/month5 GB / Pooled data plan
Standalone 4G/5G camera with motion-only upload500 MB - 2 GB/month2 GB plan
1080p H.265 24/7 streaming camera50-150 GB/monthEnterprise pooled data + cost study
Continuous 4K streaming200-500 GB/monthOnly sensible with fiber backhaul; cellular is not cost-effective

Indicative figures with H.265 compression. H.264 doubles consumption. Continuous cellular streaming has prohibitive cost; realistic architecture = local recording + selective event upload.

When to use static IP

  • The NVR must be reachable from the NOC or integrator team for diagnostics, configuration, and remote recording review.
  • The cloud VMS requires connection from a registered source IP (per-customer allowlist) to accept streams.
  • Regulatory audit (GDPR, banking, defense) requires per-IP traceability of each camera or NVR.

When to use private APN

  • Streams contain personal data (faces, license plates, children at schools, patients at clinics) and GDPR mandates network segmentation.
  • Critical infrastructure deployment (banking, defense, energy) where private network is a customer requirement, not an option.
  • High risk of targeted attacks on Hikvision/Dahua cameras — private APN makes them unreachable from the public Internet.

Frequently asked questions

Can I record 24/7 at 1080p over a 4G SIM?
Technically yes, but not cost-effective. A 1080p H.265 camera at continuous 15fps uses ~50-150 GB/month. At standard per-GB rates, that's hundreds of euros per month per camera. The sensible architecture is: local NVR recording + selective event upload (motion, intrusion) + on-demand access. That drops consumption to 1-10 GB/month.
Do I need static IP for the customer's app to work?
For apps that connect directly to the NVR (Hik-Connect, DMSS, Genetec Mobile) yes — the app needs a stable endpoint. Without static IP you depend on proprietary P2P cloud services that add latency and vendor lock-in. With static IP + firewall ACLs, you control access.
How do I meet GDPR with cameras at a construction site or public venue?
Three requirements: visible signage informing of recording + DPIA if high-risk + limited retention (typically 30 days, except for events). GDPR applies the moment images can identify a person. Cameras with on-edge analytics that only count or detect events without recording significantly reduce risk.
Will 4K streaming work on normal 4G coverage?
Depends on coverage quality. Stable 4K H.265 at 15fps needs ~10-15 Mbps sustained. On strong 4G LTE coverage (>-90 dBm RSRP) yes; on marginal or congested 4G, no. For critical 4K, use 5G where available or downscale to 1080p over 4G.
What if my construction-site NVR gets stolen?
If you only record locally, you lose the incident recordings — including the theft itself. The defensive architecture is: cameras + local NVR + simultaneous event upload to the cloud. Even if the NVR is stolen, the cloud retains the theft event clips. Extra cost: backhaul data plan, but it pays off on high-value projects.
Why do experts recommend not exposing Hikvision/Dahua cameras to the Internet?
Both vendors have a history of critical CVEs (CVE-2017-7921, CVE-2021-36260, etc.) exploited at massive scale by botnets. If the camera is reachable from the public Internet, it will be compromised within hours or days, especially without monthly firmware updates. Solution: private APN, or NAT with port forwarding only to specific IPs. Never exposed.

Pre-deployment checklist

  • 1Per-site inventory: cameras (model, resolution, fps), NVR (model, capacity, channel count), cellular router if applicable.
  • 2Realistic consumption estimate based on architecture (continuous vs event) and plan sized at 2x.
  • 3Static IP decision (recommended for remote access) vs dynamic IP.
  • 4Public APN with encryption vs mandatory private APN if personal data or customer requires it.
  • 5Camera and NVR firmware update policy (monthly minimum).
  • 6GDPR compliance: signage, DPIA, retention, documented legal basis.
  • 7NVR theft response procedure — is simultaneous cloud upload active?
  • 8SIM or router ACL configuration so only the customer's team can access the NVR.
  • 9Camera and NVR configuration backup plan (if equipment is lost, what's the rebuild cost?).
  • 10Pilot of 1-2 sites for 1 month verifying real data consumption, remote access latency, and failover robustness if multi-SIM.
