Controller, reader and cybersecurity planning
Bosch AMC2 wiring, firmware, I/O, readers and mobile access
Select the exact AMC2 variant and official installation manual before designing doors, readers, power, supervised inputs, relays, extensions or firmware changes.
Hardware planning matrix
| Component | Purpose | Field verification |
|---|---|---|
| AMC2-4WCF | Four Wiegand reader interfaces with local decision/event capability. | Entrance model, one/two-reader doors, power, Ethernet, RS-485, inputs, relays, enclosure and firmware. |
| AMC2-8IOE | Eight-input/eight-output expansion for auxiliary monitoring and control. | Supported base controller, addressing, bus length, power, supervision and fail state. |
| OSDP controller/readers | RS-485 reader communications supporting modern secure-channel designs. | Reader/controller compatibility, encryption keys, addressing, termination and migration. |
| Mobile Access | AMS/BIS software, OSDP controller, BLE-capable readers, backend/app and credential subscription workflow. | Exact supported versions, licenses, phone population, enrollment, revocation and outage behavior. |
Credentials and readers
Do not describe every P-style reader or smart card as automatically supporting MIFARE DESFire EV3. Verify the exact reader datasheet, credential technology, keys, application identifiers and supported secure mode. Migration must address existing badges, issuance, revocation, lost cards and fallback—not only frequency.
Wiegand migration
May preserve installed readers but should include a security review because interface behavior, supervision and credential protection differ from OSDP Secure Channel.
Mobile credential rollout
Budget backend/software entitlements, compatible controller and BLE readers, subscriptions, administrator workflow and help-desk ownership. Do not publish the unverified $3,045 reseller bundle as a universal subscription cost.
Firmware and PSIRT workflow
- Identify exact model, hardware revision, current firmware and managing AMS/BIS release.
- Review the official Download Store release notes and Bosch/Keenfinity security advisory.
- Validate compatibility, checksum, backup, maintenance window and rollback.
- Update a controlled device group, then test communications, offline decisions, inputs, relays and event recovery.
- Record firmware, checksum, date, technician and acceptance evidence.
Installation, repair and maintenance
We install and service AMC controllers, extensions, readers, credentials, power supplies, doors and network interfaces as part of an authorized, documented enterprise system.
