Access Systems Fundamentals

Access control has stopped being a wiring trade. Modern systems are IP-based, software-driven, and tied into the customer's network as deeply as their CCTV. An installer who only knows the door-side hardware will run into ceilings within months. This plan is built around that reality: it bundles the full Access Systems Fundamentals course with the full Network Fundamentals course, because you need both to do the trade properly — and you get both for $99.

14 hours of structured video, 14 days of access — across two complete courses.

Course 1 — Access Systems Fundamentals (6 hours)

What access control is and how a system fits together

• What access control actually is — beyond "keys you can switch off".
• The three factors of authentication — something you have, something you know, something you are — and how real systems combine them.
• The complete system on one diagram — credentials, readers, controllers, locks, software, network.
• Access control vs mechanical keys — the practical and audit differences customers care about.

Credentials

• Proximity cards and fobs — the legacy 125 kHz formats and where they still appear.
• Smart cards: MIFARE, DESFire, encrypted credentials. The reasons modern installs avoid plain prox.
• PIN codes — when they are appropriate and when they are a liability.
• Mobile credentials — Bluetooth, NFC, and the cloud back-end every mobile credential depends on.
• Biometrics — fingerprint, face, vein, and the install considerations each one brings.

Readers

• How a card reader actually reads a credential.
• Reader types — proximity, smart, multi-technology, keypad, biometric.
• Reader positioning and accessibility — DDA / ADA, mounting heights, weather.
• Wiegand vs OSDP. Why OSDP is the modern standard, and what to do on sites still running Wiegand.

Door controllers

• What a door controller is and what it has to do.
• Controller architecture — single-door, multi-door, distributed vs centralised.
• Inputs and outputs on a controller board — REX, door contact, lock relay, auxiliary I/O.
• Standalone vs networked — and the migration path between them.

Locking devices

• Electromagnetic locks (maglocks) — holding force, fire-egress requirements, brackets.
• Electric strikes — fail-safe and fail-secure variants, frame compatibility.
• Other locking devices — drop bolts, motorised locks, deadlocks with monitoring.
• Fail-safe vs fail-secure — the rule that decides which side of a door each lock belongs on, and what fire and life-safety codes require.
• Key override and emergency release — the legal and practical considerations.

Power and wiring

• Powering access control — voltage, current, voltage drop on long cable runs.
• Battery backup sizing.
• Cable types and topologies for readers, controllers and locks.
• Wiring a complete door — a cable schedule from controller to reader to lock to door contact to REX.

IP and cloud architectures

• IP-based access control — when controllers sit on the LAN.
• RS-485 and TCP/IP communication — the field-bus and network layers, side by side.
• Cybersecurity for access control — the most overlooked liability on a modern site.
• Cloud-based access control — what the architecture actually looks like, and what the trade-offs are.

Software, schedules and operations

• Access control software — what every package has in common.
• Cardholders, credentials and permissions.
• Access levels, schedules and time zones.
• Events, alarms and reporting.
• Enrolment — adding users efficiently.

Advanced features

• Anti-passback — the rules and the configuration.
• Interlocking and mantraps — secure rooms and high-security entries.
• Mustering and roll-call — life-safety integrations.
• Elevator control — high-rise and floor-by-floor restriction.
• Visitor management — pre-registration, badges, audit trails.

Integration with other systems

• Integration with intruder alarms — set/unset on entry, alarm acknowledgement.
• Integration with CCTV — event-driven recording and visual verification.
• Integration with fire alarm — release on alarm, with the right safeguards.
• Building management integration — HVAC, lighting, occupancy.

Site work, commissioning and fault-finding

• Site survey and door schedule.
• Installing readers, controllers and locks cleanly.
• Commissioning, testing and handover.
• Common installation mistakes that cost callbacks.
• Systematic fault-finding.
• Common faults and how to recognise them quickly.
• Preventive maintenance and service schedules.

Course 2 — Network Fundamentals (8 hours, included)

Modern access control runs on the network. Door controllers sit on the LAN; mobile credentials go through the cloud; integrations with CCTV and intruder all happen over IP. Without networking, the install stops at the door. This course gives you the IP foundations: addressing, subnets, switches, PoE, VLANs, bandwidth, secure remote access, and how to actually talk to the customer's IT department.

The Network Fundamentals course is included with this plan at no extra cost — bought separately, the same content is $69 on its own. The combined plan is the right plan for installers serious about doing access control work on modern, networked sites.

Who this plan is for

• Locksmiths and door-hardware installers extending into electronic access control.
• Electricians taking on access work as part of low-voltage and security install jobs.
• CCTV and intruder installers adding access control to a single-trade business.
• Junior access engineers who learnt one platform on the job and need the underlying principles.
• IT staff who suddenly own an access control system and need the trade context to support it.

What you will be able to do at the end

Read a door schedule and produce a wiring plan. Choose the right reader, controller, lock and credential combination for the threat level and the doorset. Wire and terminate readers, controllers and locks against a clean cable schedule. Configure a controller, software and access levels for a small to mid-sized site. Specify the network the system needs and configure the relevant switches, VLANs and PoE. Commission, document and hand over. Diagnose faults methodically across the door, the network and the software stack.
