The Fanvil i504 is built for that job: a 7-inch SIP indoor station for villas, apartments, offices, hotels, and residential community projects. It gives the user a wall-mounted colour screen for visitor calls, two-way hands-free talk, live video from door phones or linked IP cameras, door release, alarm inputs, and message handling. The i504W is the same model family with dual-band Wi-Fi added for sites where a network cable is not available at the final wall position.

For Dubai projects, this is usually specified by an ELV contractor, villa automation team, system integrator, or building management buyer. A Jumeirah villa, a Dubai Hills townhouse, a Business Bay office entrance, a serviced apartment floor, a staff accommodation block — the requirement is the same: visitors call from the door station, the indoor screen rings, the resident or receptionist sees who is outside, speaks hands-free, and releases the door from the wall unit.

What the Fanvil i504 is

The i504 is a SIP indoor station with a 7-inch IPS colour capacitive touchscreen at 1024 × 600 resolution. It is wall mounted, slim at 22.5 mm deep, and sized for indoor entrance control points where a normal desk handset looks wrong and a mobile app is not enough. The front screen is for the person inside the property. The door phone or entrance station sits outside. The SIP platform sits behind both.

It supports SIP 2.0 over UDP, TCP, and TLS. Audio is hands-free through the built-in 2 W speaker with acoustic echo cancellation, so the user can speak to the visitor without lifting a handset. Video decoding supports H.264, with H.265 optional, and display resolutions up to 1080p from compatible sources. That makes it useful for more than one door station: it can also show live video feeds from linked IP cameras when the project design needs a side gate, service entrance, reception camera, or delivery bay view.

The i504 connects to the network through one 10/100 Mbps RJ45 Ethernet port. Power is by PoE 802.3af or 12 VDC, 1 A. The i504W adds built-in dual-band Wi-Fi at 2.4 GHz and 5 GHz, which matters in retrofit villas and apartments where the old intercom cable path does not end at a clean data point.

This page covers the i504 and i504W as the same project family. Choose i504 where the wall position has Cat6 and PoE available. Choose i504W where the indoor station must join Wi-Fi because the wall point cannot be cabled without rework. For new Dubai fit-outs we still prefer wired PoE where possible. It is cleaner, powered from the comms room, and easier to support after handover.

SIP accounts and call handling — what to size on an indoor station

Desk phones are sold by SIP line count. Indoor stations are different. Fanvil does not position the i504 as a multi-line office phone; it is a SIP 2.0 indoor station for entrance calls, monitoring, messages, alarm events, and door release. So the right sizing question is not “how many trunk calls can it make?” The right question is: which door phones, indoor stations, IP cameras, and PABX extensions need to talk to this wall screen?

In a villa, the design might be simple: one outdoor door phone at the gate, one i504 in the living room, and one call path to the owner’s extension or mobile app through the PABX. In a residential community, the design can be larger: an i504 inside each unit, a guard room extension, multiple entrance stations, and a management desk. In an office building, the i504 can sit behind a reception door or server room entrance so staff can see and speak to visitors before pressing the release key.

This is the same mistake we see in PABX replacement projects: buyers oversize the wrong number. For an i504 project, the wall screen does not need 20 desk-phone lines. It needs the correct SIP registration, the correct door phone pairing, correct relay permissions, correct camera view, and a clean power path. That is what we stage before dispatch from Dubai.

The 7-inch screen is the point

A door call is visual. The person inside wants to see who is outside before opening the door. The i504’s 7-inch IPS touchscreen gives enough room for visitor video, on-screen controls, call status, and simple day-to-day use. It is not a small keypad with a tiny preview. It is a wall screen meant for family members, reception staff, security guards, hotel staff, and facilities teams who may not care what SIP means but do care that the button does what it says.

In a Dubai villa, that means the resident can see the gate camera, speak to the driver or delivery person, and release the gate without walking to the entrance. In a JAFZA warehouse office, the indoor station can let admin staff answer a loading-bay visitor while keeping the office door controlled. In a serviced apartment, the same model family can give each unit a fixed screen for lobby calls without giving every guest access to the building security system.

The screen also supports linked IP camera viewing. That gives integrators a useful design choice: the door phone handles the call, while another camera can show a wider angle — gate approach, parking barrier, reception corridor, or service entrance. When paired with a Fanvil door phone, the i504 becomes the indoor side of a complete SIP entrance system.

Inputs, outputs, and the hidden value for ELV projects

The i504 is not only a screen. It has eight alarm inputs, one short-circuit output, one doorbell input, and one reserved RS-485 interface. That matters for ELV work because an entrance system often touches more than one trade: door contact, panic button, sensor, bell input, relay output, guard room call, and PABX registration. A cheap screen may show video. A proper indoor station gives the contractor connection points to finish the job without adding extra boxes for basic signals.

For villa projects, the alarm inputs can support contact-type signals around the entrance design. For offices, they help when the indoor station sits near a controlled room or staff-only door. For residential communities, they give the integrator a cleaner way to map events back to the indoor screen and management call flow. The exact wiring depends on the access controller, lock type, and project drawings, so we review the IO requirement before quoting project quantities.

Where the i504 fits in a UAE project

The i504 fits best where the buyer wants a fixed indoor answer point. Villas with gates. Apartment units with lobby entrances. Offices with controlled reception doors. Hotels and service apartments where staff need a known wall device instead of depending on a mobile phone. Community management rooms where a guard desk must call or receive calls from indoor stations.

For wired projects, the i504 is the tidy choice: Cat6 to the wall point, PoE from the comms room, SIP registration on the PABX, and door phone pairing tested before dispatch. For retrofit projects, i504W saves the wall. Dual-band Wi-Fi lets the indoor station work where the existing cable route is wrong, damaged, or not worth reopening after paint and joinery are complete.

Vector Digital Systems supplies Fanvil indoor stations from Dubai for single villas, small office access-control jobs, and multi-site projects. We also map the indoor station with the wider Fanvil IP phone and intercom range, so the same engagement can cover reception phones, door stations, indoor monitors, paging, and PABX endpoint staging.

Power and network — the wall point decides the variant

The Fanvil i504 has one 10/100 Mbps Ethernet port and supports PoE 802.3af. Power can also be supplied through 12 VDC, 1 A. In a new villa, office, or residential fit-out, the clean design is Cat6 to the wall point and PoE from the comms room. One cable carries data and power. No visible power brick beside the indoor screen. No local socket dependency at the entrance wall.

For retrofit work, the i504W gives the contractor another option. It adds dual-band Wi-Fi at 2.4 GHz and 5 GHz. That matters when the wall has power nearby but no usable data point, or when reopening the wall after joinery, marble, or paint is not acceptable. We still check Wi-Fi strength before approving that route. An indoor station is part of the access system. Weak Wi-Fi becomes weak door answering.

For project quantities, send the floor plan or door schedule before ordering. We mark which indoor stations should be wired i504 units and which locations genuinely need i504W. That saves the common Dubai retrofit mistake: buying Wi-Fi screens for every wall when half the points already have data cable behind the old intercom.

Current i504 features that help at handover

The i504 family is useful because it is not just a video answer screen. It supports local discovery of Fanvil door phones and indoor stations on the same network, so staging and site pairing are faster when the door hardware, guard room device, and indoor monitors are all on the project LAN. That is a real handover saving in villas, staff accommodation, and small residential buildings where multiple screens must find the same entrance station.

The indoor station can show live video from linked IP cameras, not only the main door station. For a villa, that can be the pedestrian gate plus a driveway angle. For a warehouse office in DIP or JAFZA, it can be the reception entrance plus the loading-bay door. For a serviced apartment, it can be the lobby camera with the apartment call. We confirm camera format and path during staging before dispatch.

There are also small operator details that make the unit easier to live with: custom incoming call ringtones, message send and receive, DND schedule, monitoring permissions, missed-call snapshots, manual screenshots during a call, SOS emergency call options, and Arabic interface support. These are the features buyers rarely see on UAE supplier pages, but they come up after installation when residents and facilities teams start using the system daily.

For managed buildings, the i504 can also fit into a call path that includes a management centre or guard desk. That lets the indoor station work as part of the building’s access flow rather than a standalone screen. The exact layout depends on the Fanvil door station, PABX platform, network design, and whether the site needs apartment-to-guard, guard-to-apartment, or door-to-apartment calling.

PABX and platform compatibility in Dubai

The Fanvil i504 uses SIP 2.0 over UDP, TCP, and TLS. That makes it a fit for common SIP platforms used in UAE projects, including 3CX, Grandstream UCM, Yeastar, Asterisk-based systems, and SIP intercom environments built around Fanvil door phones. It can sit on the same voice network as the office PABX, or on a dedicated intercom VLAN where the ELV design separates door access from desk phones.

Etisalat and du matter where the indoor station must call an external number or where a PABX is tied into licensed UAE SIP trunks. For most intercom layouts, the i504 speaks to door stations, reception, guard room, and internal extensions. If the project requires calls outside the building, we check the PABX routing, operator trunk, and TRA context before we commit the call path.

Fanvil i501, i504, or i506W — indoor station comparison

For most Dubai villa and office projects, the i504 is the balanced choice. It gives the user the screen they expect, keeps the hardware compact, and still gives the integrator alarm inputs, doorbell input, output control, SIP registration, camera view, and PoE power. The i501 family is better where video is not part of the design. The i506W is better where the client wants a larger wall screen and the project budget supports it.

Pricing, supply, and staging from Dubai

Vector Digital Systems supplies the Fanvil i504 and i504W from Dubai for villa intercom, office entrance, residential building, and hospitality projects. Same-day AED quotes are available on WhatsApp. For project quantities, we quote the indoor stations, door phones, PSU add-ons where needed, VAT breakdown, delivery, and installation scope in one offer.

Project buyers can send a door schedule instead of a retail shopping list. Tell us the number of gates, apartments or rooms, indoor screens, guard room points, reception extensions, and whether the site already has Cat6 at each wall position. We then map i504, i504W, door phone, and PABX registration before the quote goes out.

Frequently asked questions

Will the Fanvil i504 work with our 3CX / Grandstream UCM / Yeastar system?

Yes. The i504 uses SIP 2.0 over UDP, TCP, and TLS, so it can register to common SIP platforms used in Dubai projects, including 3CX, Grandstream UCM, Yeastar, and Asterisk-based systems. We register the indoor station, pair it with the door phone, test video, and confirm the door release path during staging.

Does the Fanvil i504 come with a power adapter, or do I need PoE?

The i504 supports PoE 802.3af and 12 VDC, 1 A power. We do not assume the DC adapter is inside the box unless the pack list is confirmed for that batch. If your site has a PoE switch, one cable powers and connects the indoor station. If not, we quote the correct Fanvil PSU as an add-on.

What does SIP mean on the i504 — can it make normal phone calls?

SIP means the i504 registers as an IP endpoint on your intercom or PABX platform. It is mainly used for door station calls, guard room calls, reception calls, indoor station communication, and door release. External calling depends on your PABX routing and licensed Etisalat or du SIP trunk setup, not the indoor station alone.

Fanvil i504 vs i506W — what is the difference?

The i504 has a 7-inch IPS touchscreen and is available as i504 or i504W with Wi-Fi. The i506W has a larger 10.1-inch IPS touchscreen and includes dual-band Wi-Fi. Choose i504 for most villas, offices, and apartment indoor points. Choose i506W when the client wants a larger wall screen.

Does the i504W work on our existing office or villa Wi-Fi?

Yes, the i504W supports 2.4 GHz and 5 GHz Wi-Fi. The Wi-Fi must be stable at the wall point because call quality and video view depend on it. For new projects we prefer wired PoE. For retrofit villas and apartments, we test Wi-Fi strength before approving i504W placement.

Can the Fanvil i504 show our gate camera or IP camera?

Yes. The i504 can show live video from linked IP cameras and compatible door stations. It supports H.264 video decoding, with H.265 optional, and video display formats up to 1080p from compatible sources. We check camera format, network path, and user permissions during staging.

Does Vector Digital Systems configure the indoor stations before delivery?

Yes. Staging is standard for project quantities: SIP account registration, provisioning template, door phone pairing, camera view test, two-way audio test, door release test, room labels, and site-wise packing before dispatch from Dubai.

Is VoIP legal in the UAE and will this work with Etisalat or du?

Business VoIP over licensed operators is standard in the UAE under TRA regulation. The i504 can work inside a licensed business voice setup through your PABX and Etisalat or du SIP services where external call routing is required. For normal door intercom use, most calls stay within the site network.

Is the Fanvil i504 covered under Fanvil warranty in the UAE?

Yes. Vector Digital Systems supplies Fanvil products from Dubai with Fanvil manufacturer warranty handling for UAE projects. We support warranty coordination for supplied units and keep the project documentation ready for procurement and facilities teams.

Who is the supplier of Fanvil i504 in Dubai?

Vector Digital Systems LLC is an authorised Fanvil supplier in Dubai, UAE, operating since 2009.

What is the best Fanvil indoor station for villa gate intercom projects in Dubai?

For most villa gate intercom projects, the Fanvil i504 is the right 7-inch indoor station: SIP 2.0, colour touchscreen, PoE, 12 VDC power option, alarm inputs, doorbell input, live camera view, and door release from the wall screen. If the client wants a larger display, step up to the Fanvil i506W.
