Cellular Gateways & LTE/5G Routers

Dual-SIM LTE/5G edge routers with automatic failover for sites lacking reliable wired broadband. Purpose-built for remote surveillance access and distributed site connectivity.

Industrial WAN Routers

Hardened routers for harsh environments with DIN-rail mounting, wide temperature ranges, and redundant power inputs. Support site-to-site VPN, dynamic routing, and multi-carrier load balancing.

VPN & Secure Edge Appliances

Gateway-class firewalls and VPN concentrators for encrypting surveillance feeds across WAN links and protecting remote site access. Often integrate VLAN management and stateful inspection.

PoE-Injecting Routers & Gateway Switches

Integrated PoE+ delivery combined with WAN routing, reducing infrastructure footprint in constrained cabinet deployments and remote enclosures.

Outdoor & Pole-Mount Gateways

IP67/IP68-rated cellular or Ethernet routers designed for exterior mounting at tower bases, utility poles, or remote camera sites. Integrated antennas and weatherproof connectors.

Vehicle & Mobile Gateways

Compact LTE/5G routers with vehicle power conditioning, GPS integration, and mobile-optimized failover for surveillance in transport fleets and mobile command centers.

What to Look For When Buying

The decisions that matter most before you spec.

Carrier & Bandwidth Redundancy

Multi-carrier support and dual-SIM failover prevent single points of failure when primary WAN links drop. Prioritize devices supporting 5G SA/NSA and regional carrier bands. See Why Surveillance Systems Fail During Incidents for impact analysis.

Throughput Under Load & Concurrent Streams

Router CPU and backplane must sustain peak camera bitrate across all active connections without throttling. NVR throughput limits compound with undersized WAN routers—verify throughput specs under VPN encryption, not just bare Ethernet.

PoE Power Budget & Injection Method

If planning PoE delivery at remote sites, confirm the router's PoE+ output (watts) matches your camera + accessory load. Inline injectors via dedicated PoE midspans are more reliable than router-integrated PoE for larger camera counts.

Environmental & Power Conditioning

Industrial deployments require wide temperature (-40°C to +70°C typical), voltage tolerance (9–48VDC or 85–264VAC), and redundant power inputs. Outdoor installations demand IP67 or higher ratings and surge/lightning protection on all Ethernet and cellular antenna ports.

Network Core Capacity Planning

See Why Surveillance Networks Collapse at the Core—routers are only the edge. Confirm your core network switches and backbone can handle the aggregated bitrate from all remote sites before selecting gateway throughput.

Firmware, Feature Parity & Vendor Lock-in

Evaluate whether router firmware updates support new encryption standards, carrier band additions, and critical CVE patches. Prefer vendors like Cradlepoint, Digi International, and Lantronix with transparent roadmaps and multi-year support.

Technology Stack

The specs and acronyms that actually affect routers & gateways performance.

LTE/5G Band Support & Carrier Lock

Verify the gateway supports all bands (B1–B71+) deployed by your chosen carriers in your region. Some devices lock to a specific carrier's firmware; others allow SIM-agnostic switching. Regional variants (USA, EU, APAC) often have different band sets—confirm before purchase.

VPN Throughput & Encryption Overhead

IPSec, WireGuard, or OpenVPN encryption reduces effective throughput by 10–30% depending on cipher suite and CPU capability. Routers specify 'encrypted throughput' separately from bare Ethernet—always compare apples-to-apples specs for your intended security protocol.

Failover & Load Balancing Logic

Options include active-active (simultaneous use of both WAN links), active-passive (switch on primary failure), or application-aware (video streams over LTE, management over Ethernet). Look for sub-second failover detection and configurable health-check intervals.

PoE+ Standard & Injector vs. Integrated

802.3at (30W) or 802.3bt (60–90W+). Integrated PoE in routers often provides only 30W or 60W total budget across all ports. Separate PoE midspans allow per-port power management and cleaner power delivery isolation from WAN switching noise.

Management Interface & Remote Monitoring

Cloud-based management (e.g., Cradlepoint NetCloud) vs. on-premise control; REST API availability; syslog export; SNMP support. For distributed surveillance, confirm the gateway supports centralized monitoring and alerting of connection status and failover events.

VLAN & Traffic Segmentation

802.1Q VLAN tagging and trunk support allow surveillance, IoT, and management traffic to be isolated on separate logical networks. Critical for compliance (HIPAA, PCI) and preventing camera bandwidth from starving management or access-control traffic.

Typical Deployment Scenarios

Multi-Site Retail Chain (50 locations, Ethernet + LTE hybrid)

Each store location uses a Cradlepoint or Digi dual-SIM cellular gateway with primary Ethernet WAN and LTE failover. 4 cameras per location (~8 Mbps peak per site) aggregate to central NVR via site-to-site VPN. Dual-carrier SIM cards (Verizon + T-Mobile) prevent single-network outages during incidents.

Remote Industrial Facility (no wireline ISP, 24 cameras + sensors)

Pole-mounted IP67 5G gateway provides primary WAN; secondary LTE module activates on 5G degradation. IoT sensors and 24 surveillance cameras (30–50 Mbps aggregate bitrate) tunnel through IPSec VPN to headquarters. Power sourced from solar + battery with 48VDC input conditioning in the gateway.

School Campus Multi-Building (7 buildings, distributed PoE)

Central fiber backbone connects main building router to 6 satellite gateways; each satellite uses PoE injector + Ethernet uplink and integrated dual-SIM LTE for failover. See School Surveillance System Design Guide for multi-building planning. Total system: ~150 cameras, network switches at each building feed into satellite routers for WAN aggregation.

Mobile Command Center (vehicle-mounted, GPS + dual LTE)

Vehicle gateway with GPS integration, 12–48VDC power input, and dual-SIM with active-active load balancing across carriers. Supports 8–12 mobile cameras on vehicle + drone feeds. LTE throughput peaks at 30 Mbps per SIM; dual-SIM active load balances to ~60 Mbps total headroom. Failover to backup carrier automatic within <1 second.

Frequently Asked Questions

What's the difference between a 'router' and a 'gateway' in surveillance deployments?

A router typically handles basic WAN connectivity and VLAN switching. A gateway adds security features (firewall, VPN termination, intrusion detection) and often integrates cellular/LTE for failover. For surveillance, the terms overlap—most modern 'cellular gateways' include routing and VPN capabilities. Choose based on your security and redundancy needs, not terminology.

How do I know if a dual-SIM gateway will actually failover fast enough for surveillance?

Look for sub-second failover detection (typically 500–800 ms) and confirm the router supports 'watchdog' health checks on both WAN links. Test with your actual carrier SIMs and the exact VPN configuration you'll deploy—lab failover times often differ from field conditions. Surveillance system failure modes show that failover speed matters most during network congestion.

Can I use a PoE-injecting router to power all my remote cameras, or do I need a separate PoE switch?

Most PoE-injecting routers provide 30–60W total PoE budget across 2–4 ports. If your remote site has 3+ cameras (typically 12–15W each), a separate PoE midspan or injector is safer—it isolates power delivery noise and gives per-port current limiting. For 1–2 cameras, integrated PoE in the router often suffices.

What's the typical lifespan and support window for a cellular gateway?

Premium vendors like Cradlepoint and Digi International typically offer 5–7 years of firmware security updates and 7–10 years of hardware availability. Budget $800–$3,000 per unit, with annual cloud management licenses ($200–$500) if using hosted monitoring. Industrial variants may cost 20–30% more but justify themselves in remote sites with 10+ year lifespans.

Do I need a firewall appliance in front of my gateway, or is the gateway's built-in firewall enough?

Gateway firewalls are adequate for most surveillance deployments—they inspect VPN traffic, block WAN inbound connections, and segment traffic via VLAN. You don't need a separate hardware firewall unless you're routing untrusted guest traffic or meeting compliance requirements (PCI-DSS, HIPAA) that demand external audit. Confirm your gateway's stateful inspection can handle your peak camera bitrate without CPU bottleneck.

How do I plan bandwidth if I'm mixing Ethernet and LTE WAN links?

Assume Ethernet is primary and size LTE as a fraction of your peak bitrate—typically 50–80% of the largest camera feed. If your main camera is 4 Mbps, provision LTE with at least 2–3 Mbps headroom. Bitrate and retention calculations show that sustained LTE limits often force video compression adjustments. Test with your actual camera codec and resolution before final deployment.
