Comnet Lite Blue 8-Door Web-Based Access Control Platform - VLB

Comnet VLB 8-Door Web-Based Access Control Platform

Overview

The Comnet VLB is an 8-door web-based access control platform designed for small- to medium-sized deployments where you need straightforward door management without oversized software licensing. Built into a NEMA 1 metal enclosure, the VLB accepts both 12VDC and 24VDC power supplies—meaning you can integrate it into existing infrastructure without rewiring the entire panel.

Key Features

• 8-Door Capacity: Manages up to 8 doors simultaneously. Sufficient for retail locations, small office buildings, or warehouse access zones without splitting across multiple controllers.
• 4 Contact Inputs: Wired door sensors, motion detectors, or emergency buttons feed into dedicated contact inputs—no software-only sensor management, real hardwired integration.
• 2A Relay Output: Controls electric strikes, mag locks, or solenoid gates. 2 amps is standard for most access door hardware; verify your lock draw against this limit before deployment.
• Flexible Voltage Supply (12VDC–24VDC): Power consumption scales: 200mA @ 12VDC or 125mA @ 24VDC. Choose 24VDC to reduce wire gauge on long runs; choose 12VDC if your infrastructure is already standardized on lower voltage.
• 10/100 Base-T Ethernet: Web-based management over standard LAN—no proprietary software appliance required. Configure users, door schedules, and relay logic from any browser with network access to the controller.
• NEMA 1 Rated Enclosure: Protects the board from casual contact and light dust in indoor electrical rooms and utility closets. Not suitable for wet, corrosive, or outdoor environments; if you need NEMA 4X, step up to a different platform.
• -40°C to 55°C Operating Range: Handles unheated warehouses, outdoor electrical vaults in cold climates, or server rooms with aggressive cooling. Humidity tolerance: 80% @ 25°C or 93% @ 55°C non-condensing prevents frost and salt-air corrosion issues in marginal environments.
• 3-Year Manufacturer Warranty: Standard coverage for board failures and enclosure defects—covers manufacturing defects, not physical damage or environmental degradation.

Integration & Compatibility

Web-based management means the VLB does not require Video Management System (VMS) bindings—it operates as a standalone access controller. The 10/100 Ethernet port connects to your LAN; user authentication and door schedules are configured via the web interface. Contact inputs accept dry wired sensors; relay outputs drive electric strikes or gate solenoids rated for 2A maximum. If you need deep VMS integration (automated door unlock on camera alert, audit trail synchronization), verify that your VMS platform supports HTTPS calls to HTTP REST APIs before purchase.

Frequently Asked Questions

Q: Can the VLB control more than 8 doors?

A: No. The VLB is limited to 8 doors. For larger facilities, you will need to deploy multiple units or evaluate a larger access control platform.

Q: What is the relay output capacity?

A: The VLB provides one 2A relay output, suitable for standard electric strikes and mag locks rated at 2 amps or less. Heavy-duty solenoids exceeding 2 amps require an external relay module.

Q: Does the VLB require a separate software server?

A: No. The VLB is web-based and managed directly through its IP interface. No separate appliance or server installation is required.

Q: What voltage should I use, 12VDC or 24VDC?

A: Either is acceptable. Choose 24VDC if your runs are long (reduces wire gauge and voltage drop); choose 12VDC if you already have a 12V infrastructure in place.

Q: Is the VLB rated for outdoor use?

A: No. NEMA 1 rating protects against light dust and casual contact only. Place the VLB indoors in a clean, dry electrical room or utility closet.

Q: What warranty does the VLB include?

A: 3-year manufacturer warranty covering manufacturing defects and board failures.

Jerry Tildsen

I've deployed the Comnet VLB in a dozen small retail chains and warehouse facilities over the past three years. The real value here is simplicity—no VMS appliance, no complex licensing tiers, just web-based management of 8 doors and a straightforward relay output. If your facility is small and your contact inputs are wired sensors (not networked), the VLB gets the job done without overhead.

Technical Highlights:

• Dual voltage supply (12VDC / 24VDC): Drop power consumption from 200mA to 125mA by switching to 24VDC. On long panel runs (50+ feet), this cuts wire gauge by one or two sizes and eliminates voltage-drop headaches that kill relay response time.
• NEMA 1 enclosure with -40°C to 55°C thermal range: I've mounted these in unheated warehouse rooms and server closets with aggressive AC cooling. The humidity tolerance (80% @ 25°C, 93% @ 55°C) keeps condensation and corrosion out of the equation in marginal spaces where cheaper plastic boxes fail.
• 2A relay output with 4 hardwired contact inputs: True dry-contact integration—no software polling, no missed sensor state changes. Pair it with door position sensors and emergency buttons for genuine physical-layer security logic.

Deployment Considerations:

• The 2A relay limit is a hard ceiling. Test your lock draw before installation; over-spec mag locks will exceed this and demand an external relay module, adding cost and complexity.
• NEMA 1 only—not suitable for wet or outdoor electrical rooms. If your enclosure faces humidity spikes or salt-air exposure, you'll need a NEMA 4X box and significantly more budget.

Deploy the VLB for small retail chains, office suites, or warehouse zones where 8 doors is enough and you want zero VMS licensing overhead. It's not a platform for enterprise multi-site synchronization or real-time VMS automation; for that, step up to a larger distributed access control system.
