Uniview OEU-202S-HMK4 IP Door Station, 4 Buttons, Up to 80 Monitors

The Uniview OEU-202S-HMK4 is a camera entrance panel with four call buttons, serving four flats or units from a single gate. It links up to 80 indoor stations, opens doors with IC cards, and suits small residential buildings and villas divided into apartments.

====

The Uniview OEU-202S-HMK4 is a four-button entrance panel where each button rings a different flat or unit. It is a good fit for a small four-flat building or a villa that has been divided among family members. It links up to 80 indoor stations and opens the door by card, from an indoor monitor or from the app.

Uniview OEU-202S-HMK4 key specs

The HMK4 uses the same metal 202S housing (96 × 176 × 33 mm) and adds buttons and capacity:

• 4 call buttons and up to 80 indoor stations.
• 13.56 MHz IC card reader storing 10,000 cards.
• 127.9° diagonal field of view, adaptive IR and digital WDR.
• IEEE 802.3af PoE at 6.48W, or 12V DC at 5.35W.

One panel instead of four doorbells

Small apartment blocks in Riyadh and Dammam often end up with a separate doorbell for every flat, cluttering the entrance. With the HMK4, a visitor presses the flat's button, that flat's monitor rings, and the resident sees who is there before opening. With 80 monitors available, each flat can have more than one, say by the front door and in the living room.

Resident access with IC cards

Each resident carries an IC card to open the entrance, with room for 10,000 cards. When a tenant leaves, you delete their card instead of changing the lock. Two lock outputs support electric and magnetic locks, for example the lobby door and a parking gate. For magnetic locks a dedicated access control power supply is recommended, since the unit's own power output is 12V / 0.25A and can be switched off in the web interface.

Installing at the building entrance

Mount it on the wall with its bracket or flush in an optional recess box for a cleaner facade. The metal body carries IP65 and IK08 ratings, has a tamper alarm and runs up to +60°C. The IP65 rating depends on sealing the gap between unit and wall. With PoE, a single cable from the building switch handles power and data.

Compatibility

It pairs with Uniview indoor monitors such as the OEI-372S-H-W over Uniview's private protocol, and with the UNV-Link app for remote answering and door release. It also has RS485, Wiegand and 4 IO inputs, and batch configuration speeds up multi-unit setups.

Typical Saudi projects

• Small residential buildings with four flats.
• Villas split between three or four married sons.
• Compounds of four villas behind one shared gate.

HMK4, HMK2 or OEU-301S-HMKA?

The HMK4 and HMK2 match on camera, interfaces, protection and power. They differ in buttons (4 vs 2) and capacity (80 vs 40 monitors). For more than four flats, the OEU-301S-HMKA apartment station uses a keypad and supports up to 500 indoor stations.
