Is Comnet the same as Transition Networks or Moxa?

Comnet is in the same industrial Ethernet category but engineered specifically for video surveillance and security networks — PoE budgets tuned for cameras, ring recovery times optimized for continuous video streaming, VLAN templates for camera/NVR/VMS segmentation. Transition Networks and Moxa are general-purpose industrial Ethernet brands with broader industrial application support; Comnet is surveillance-first.

What is CLFE Ethernet-over-UTP and when do I use it?

CLFE transmits Ethernet data over telephone-grade twisted-pair wiring for distances up to 1,500+ feet — far beyond standard Cat5e/Cat6 100m limits. Use CLFE for retrofit IP camera deployments where existing telephone-grade UTP wiring is in place but new Cat5e/Cat6 pulls would be cost-prohibitive. Common in historic buildings, legacy commercial retrofits, and cable-reuse renovation projects.

How do Comnet PoE budgets differ from general-purpose switches?

Comnet PoE+ and PoE++ budgets are allocated and managed for typical IP camera consumption profiles — cameras with built-in heaters, PTZ motors, and IR illuminators that can spike above base PoE consumption temporarily. General-purpose switches sometimes under-budget for these peak spikes, causing camera failures under cold-weather operation or IR activation. Comnet switches are engineered specifically for these camera-typical consumption patterns.

What's the benefit of ring topology for surveillance?

Ring topology provides redundancy — if any single network link fails, traffic continues via the alternate path with sub-50ms recovery. For continuous video streaming, this recovery time is below human perception — operators don't see a pause in camera feeds. Star topology would lose camera connectivity on any link failure, making ring the preferred topology for critical surveillance networks.

Does Comnet integrate with Open Options or Feenics access control?

Yes. ACRE Security (Comnet's parent company) integrates Comnet networking with Open Options access control and Feenics cloud access management — unified network + access control management for customers deploying the full ACRE security portfolio.

About Comnet

Comnet Communication Networks, now a business of ACRE Security (which acquired Comnet alongside Open Options and other access control brands), manufactures industrial Ethernet networking hardware purpose-built for video surveillance, access control, and security networks. Unlike general-purpose industrial Ethernet brands (Transition Networks, Moxa, Hirschmann), Comnet's engineering priorities center on security-network-specific requirements: PoE budget allocation tuned for IP camera power consumption, ring topology with <50ms recovery times optimized for continuous video streaming, VLAN configuration aligned with camera/NVR/VMS traffic segmentation, and management software that integrates with security management systems.

The product portfolio is organized around four core families: industrial Ethernet switches (CNGE managed and unmanaged, DIN-rail or rack-mount, extended temperature -40°C to +75°C for outdoor and industrial cabinet deployments), fiber media converters (CNFE and CNMCSFP, 10/100/1000 Mbps copper-to-fiber conversion for extending camera runs beyond 100m UTP limit), PoE infrastructure (PoE+ and PoE++ injectors, PoE extenders, outdoor-hardened PoE for perimeter deployments), and Ethernet extension (CLFE Ethernet-over-UTP for reusing existing twisted-pair wiring in retrofit installations).

Comnet is NDAA Section 889 compliant and approved for U.S. federal procurement, state and local government, and critical-infrastructure deployments. The ACRE Security ownership provides long-term product roadmap stability and integration with Open Options access control, Feenics cloud access, and other ACRE physical security portfolio products.

Where Comnet Fits

Comnet fits every video surveillance and security network deployment where industrial-hardened Ethernet infrastructure is required. Typical applications include perimeter camera backhaul (CNGE managed switches at perimeter cabinets with fiber backbone to NVR closet), parking lot IP camera deployments (CLFE Ethernet extenders reusing existing UTP, CNMCSFP media converters for fiber runs beyond 100m), campus surveillance (CNFE fiber ring topology with <50ms recovery, inter-building redundancy), retrofit projects (CLFE extenders reusing legacy telephone-grade UTP wiring), outdoor-hardened deployments (-40°C to +75°C switches in unconditioned outdoor cabinets), and critical-infrastructure video surveillance (federal, utility, transit) requiring NDAA-compliant industrial networking. Comnet is specified for surveillance-first deployments where general-purpose industrial brands' feature sets don't align with camera-specific network requirements.

Why Choose Comnet

Surveillance-First Industrial Ethernet

Engineered specifically for video surveillance networks — PoE budgets tuned for cameras, ring recovery <50ms for video continuity, VLAN for camera/NVR/VMS segmentation.

CLFE Ethernet-over-UTP Specialty

Ethernet extension over existing twisted-pair telephone wiring — extends IP cameras 1,500+ feet on UTP, eliminating new cable pulls in retrofit projects.

Extended-Temperature Industrial

CNGE industrial switches rated -40°C to +75°C for outdoor enclosures, unconditioned cabinets, rail trackside, and industrial deployments.

ACRE Security Ecosystem Backing

ACRE Security ownership provides long-term roadmap stability and integration with Open Options access control, Feenics cloud, and ACRE physical security portfolio.
