Access Control Systems

Access control is about knowing who can open which door, and when. We install two platforms across the Hudson Valley and pick between them on the job, not in the brochure: DMP, where access rides on the same panel as the burglary and fire system, and UniFi Access, where doors sit on the network alongside the cameras.

Either way you stop re-keying locks. A credential is deleted in software the day someone leaves, and every door event is on record.

Which platform, and why

The honest answer is that it depends on what else the building needs. Here is how we decide.

Choose DMP when

The building also needs burglary or fire. One panel, one monitoring account, one app. A badge can unlock the door and disarm the area in the same action, which no two-system setup does cleanly.

Choose UniFi Access when

The building is already on UniFi, or the doors want a camera, an intercom, and mobile or face unlock. Readers run over one PoE cable and share the console with UniFi Protect.

DMP XR150: access on the security panel

The XR150 is a combined access control, burglary, and fire panel. Doors are added with 734 Series modules, so credentials, schedules, and door events live in the same system as the alarm, and staff use one app for all of it.

  • Eight doors on the XR150, 32 on the XR550, expandable to 96
  • Access by schedule, authority level, and user profile
  • Badge to unlock and disarm the area in a single action
  • Add, change, or delete a credential from the Virtual Keypad app
  • Same panel handles burglary zones and, on FC models, fire
  • Door events in the same history as alarm events

DMP door hardware

Modules are matched to the door and the wiring that is already there.

DMP 734N network access control module

The 734N puts a door on the existing IP network and the 734N-POE runs on a single PoE cable. The 1134 goes wireless where trenching to a gate or a detached building is not worth it.

DMP 7800 Series touchscreen keypad with proximity reader

A 7800 Series touchscreen keypad arms, disarms, and annunciates in plain English, and a keypad with a built-in proximity reader can serve as the reader on a main entry door.

DMP AX-20 multi-technology access control reader

Readers support OSDP and Wiegand, 26 to 40 bit, up to eight card formats, covering prox, smartcard, key fob, biometric, and mobile wallet credentials.

DMP mobile credential on a smartphone

Mobile credentials mean no card to issue or collect. Access is granted from the app and revoked the same way, which matters most for contractors and temporary staff.

UniFi Access: doors on the network

UniFi Access puts readers on the same console as UniFi Protect, so a door event and the camera clip that goes with it sit side by side. Readers are Power over Ethernet, one cable per door back to an Access Hub, and there is no per-door licensing to keep paying.

  • NFC cards and key fobs, PIN entry, and mobile unlock
  • Apple and Google Wallet credentials on supported readers
  • Camera and two-way intercom built into the G3 Reader Pro
  • One PoE cable per reader back to the Access Hub
  • IP55 weather rating for exterior doors
  • Shared console and user directory with UniFi Protect cameras

How a UniFi Access door is put together

Readers land on an Access Hub, the hub sits on a PoE switch, and the whole thing runs from the same gateway as the network and the cameras. One system to learn and one place to look when something needs checking.

Day-to-day management

Most of the value shows up after the install, in the small things that used to take a locksmith or a site visit.

  • Doors unlock and lock on a schedule, including holidays
  • Add a new hire, or cut a leaver, in seconds
  • Remotely lock or unlock any protected door
  • Alerts on forced doors and doors held open too long
  • Entry and exit reports by person, door, and time
  • Temporary credentials for contractors that expire on their own

Reporting you can actually use

Every presentation of a credential is logged, whether it opened the door or not. That record answers the questions that come up after an incident, settles disputes about who was on site, and gives you an audit trail for insurance or a compliance review.

On a DMP system, reports are available from the Virtual Keypad app and MyVirtualKeypad.com. On UniFi Access, they come from the same console as the cameras, so a door event and its video are one click apart.
