HID 4045CGNUO EntryProx Proximity Reader, Stand Alone Access Control Unit, Charcoal Gray, Red and Green LEDs

No. The 4045CGNUO EntryProx is a stand alone access control unit, meaning the reader and the decision-making electronics are in one housing at the door. You do not wire it back to a panel or a head-end controller to make it grant access. That makes it a fit for a single opening, a small building, or one controlled door added to a site that otherwise has no access control system.

Not really the right tool. The EntryProx is a stand alone unit that makes the access decision itself, so putting it in front of an existing panel duplicates the controller you already own. If you are feeding a panel, you want a straight Wiegand reader instead, such as the SDC IPRW Series Wiegand proximity reader, which is built with 125KHz HID credential compatibility and reports to your controller rather than deciding on its own.

The HID 4045CGNUO EntryProx is a stand alone access control unit, so the reader and the door control decision live in the same housing at the opening. The SDC IPRW Series is a Wiegand proximity reader with 125KHz HID compatibility, which means it is a credential reader that sends its output to a separate access control panel or controller to make the unlock decision. If you are controlling a single door and do not want to install a panel, the 4045CGNUO EntryProx does the job on its own. If the door is being tied into an existing Wiegand head end, the IPRW is the reader-only format that architecture expects.

Not as a direct swap. The SDC IPRW Series is a Wiegand proximity reader, so it reads the credential and passes the data on, but it does not include the stand alone access control function that the HID 4045CGNUO EntryProx provides. Dropping an IPRW onto a door with no panel behind it leaves you without anything to make the unlock decision. To substitute it you would have to add a Wiegand controller and the associated relay output, which is the hardware the EntryProx already has built in.

The unit has red and green LEDs on the face, so the person at the door gets a visual indication of the read result rather than having to guess. That matters on high-traffic tenant doors where you do not want people re-presenting a card repeatedly.

Yes, if those cards are 125KHz. The SDC IPRW Series reader is listed with 125KHz HID compatibility, so an existing 125KHz HID credential population carries over. The difference between the two is architecture, not the card: the IPRW is a Wiegand reader that reports to a panel, while the HID EntryProx decides at the door on its own.

It is a proximity credential reader. Users present a prox card or fob to the face of the unit rather than entering a PIN on buttons. If your requirement is code-only entry with no credentials to issue or collect, a proximity reader is the wrong category for that opening.

Yes, it is an electronic access control device, so it requires power and connection to whatever lock or strike it is releasing. Budget for a power supply and the lock hardware separately; the reader by itself does not secure the door, it controls the release of the locking device you install with it.

The SDC IPRW Series is the one built for that scenario. It is a Wiegand proximity reader with 125KHz HID compatibility, so it reads the same 125KHz prox credentials your cardholders already carry and reports them over Wiegand to the panel you have in place. The HID 4045CGNUO EntryProx is a stand alone access control unit, which duplicates control logic you already own when there is a panel on the job. Reserve the EntryProx for openings that are not tied into a head end.

The SDC IPRW Series is specified as being 125KHz HID compatible, meaning it is designed around the same HID proximity credential technology the HID 4045CGNUO EntryProx reader is built on. On a site running a mix of both, the practical difference is not the card in the user's pocket but the architecture behind the reader: the EntryProx handles access control on its own at the door, while the IPRW hands its read off over Wiegand to a controller.

It is classed as commercial door hardware. Property managers and integrators use the EntryProx on tenant entries, back-of-house doors, storage and equipment rooms, and similar openings where you want credentialed entry without building out a full networked system.

The 4045CGNUO comes in charcoal gray, and that is the only finish this model number is built in. If your other openings are running a lighter or metallic reader face, this one will read as a dark unit against them, so plan on charcoal across the group if appearance is being standardized.
