IT Infrastructure for Residential Site Management: IP Cameras, Elevator IoT, and Dues Systems

Summary: IT infrastructure in residential site management becomes meaningful when IP cameras in common areas, elevator IoT links, dues collection systems, resident request/issue management platforms, and 5651-compliant common-area Wi-Fi are designed as an integrated whole. The classic setup — dues tracked in Excel, fault tickets written in the doorman's notebook, camera recordings on a local disk — leaves you without documentation in a KVKK audit and without follow-through on a resident complaint. A correctly designed IT infrastructure merges these three flows in one panel and cuts a site manager's day from 8 hours to 3.

In a residential site, a resident wakes up to an elevator alarm ringing all night, calls the doorman, the issue is passed to the manager in the morning, the manager calls the elevator company — the chain takes 12 hours. The dues collection report is pulled from Excel, but a resident who paid at 23:00 still appears on the "debtors" list the next morning. In a KVKK audit, pointing to the filing cabinet in the doorman's office as the answer to "where and how long do you store resident data?" is no longer a valid answer.

In this article we cover integrated IT architecture for IP cameras, elevator IoT, dues systems, and resident management platforms — aimed at residential site managers, apartment-block managers, and property management firm owners. Our target scale is residential sites and housing developments with 50-1,000 units.

Five Different Systems in Site Management

A modern residential site has five core systems that look independent on paper but should actually work as one.

1. Dues and Collections System

Per-unit dues calculation, payment tracking, late-payment alerts, invoices and collection reports.

2. Resident Requests and Fault Management

Residents submitting requests to management, status tracking, assigned personnel, and resolution-time measurement.

3. Security and IP Cameras

Cameras at the site entrance, common areas, parking, and inside elevators (within legal limits).

4. Elevator and IoT

Elevator fault/maintenance alerts, common-area heat/smoke sensors, remote meter reading.

5. Common-Area Wi-Fi (if applicable)

Wi-Fi in lobby, pool, social facilities — 5651-compliant logging is mandatory.

Managing these five systems from a single panel dramatically speeds up the site manager's day-to-day operations.

Dues and Collections System

Tracking dues in Excel works up to about 50 units; beyond that, the error rate climbs and resident complaints start.

Typical Dues Software Features

• Per-unit dues calculation (proportional to m² or fixed)
• Automatic invoicing (monthly/quarterly)
• Online payment integration (credit card, wire transfer, EFT)
• Automatic late-fee calculation
• Resident profile (contact info, unit size, tenant/owner)
• Annual audit report
• Residents see their own dues history (resident portal)

Online Payment Integration

Popular integrations at SME scale: iyzico, Param, ipara, Garanti BBVA Virtual POS. The resident logs into the portal, pays by card, and the system marks the payment automatically.

Per PCI-DSS, card data is not stored on your side; the payment provider's tokenization handles it.

Doorman/Manager Collection Mode

Some residents still pay in cash or in person. The software should include a "doorman collection" mode: the doorman enters the payment, a receipt is generated, and the resident gets an SMS notification. This minimizes "I paid but it does not show" disputes.

Resident Request and Fault Management System

Instead of "the sink is leaking" notes in the doorman's book, a centralized request system:

Request Flow

1. Resident opens a request via portal/app
2. The system auto-categorizes (water, electrical, elevator, security, etc.)
3. Management sets priority (urgent/normal/low)
4. Assigned personnel are notified
5. Personnel update the status (en route, started, completed)
6. Resident confirms completion and rates with a satisfaction score

Benefits

Classic	Modern
Requests are passed verbally, forgotten	Every request is logged and traceable
Status is unknown, residents call repeatedly	Residents track it themselves in the app
Resolution time is not measured	Average resolution-time report
Management performance is subjective	Objective satisfaction scores
Annual general meetings turn into arguments	Data-backed performance report

Annual General Meeting Report

The year-end management report shown to residents:

• Total request count (by category)
• Average resolution time
• Resident satisfaction score
• Most problem-prone areas
• Cost analysis

This report answers "management does nothing" complaints with data.

IP Camera System

Cameras are the eyes of site security. A correct design has to balance KVKK and technical considerations.

Recommended VLAN Structure

A typical segment structure for a site network:

VLAN	Purpose
10	Management (switches, routers, APs)
20	Management office (computers, printers)
30	Dues/resident software server
40	IP cameras + NVR
50	Elevator IoT, heat sensors
60	Common-area Wi-Fi (lobby, pool)
70	Guest Wi-Fi (if any)

The camera VLAN has restricted internet access (only for cloud backup). NVR access from the management office is role-based; residents under no circumstance get access.

Camera Placement Rules

What to watch for from KVKK and privacy perspectives:

• ✅ Site entrance, parking, lobby, elevator cabin (limited), common areas
• ⚠️ Garden, children's playground (heightened sensitivity for children's data)
• ❌ Angles that directly view apartment doors (neighbor privacy)
• ❌ Apartment balconies, windows
• ❌ Toilets/showers, changing rooms
• ❌ Recording neighboring buildings or public roads (unless there is a lawful basis)

An Informational Notice Is Required

A "recording in progress" sign must be posted at the site entrance and inside the elevator. The privacy notice must be shared with residents at the annual or extraordinary general meeting.

Retention Period

• Standard corridor/lobby: 30 days
• High-value areas (parking, storage): 60-90 days
• Post-incident evidence archive: 2+ years (immutable)

When the retention expires, the recordings are deleted automatically; no manual action from the manager is needed.

Elevator IoT and Sensor Systems

IoT connectivity is becoming standard in modern elevators.

Typical Elevator IoT Data

• Elevator call counts (by day/hour)
• Fault/warning codes (real time)
• Maintenance reminders (statutory cycles, wear)
• Emergency button signal (someone trapped inside)
• Door open/close counter
• Motor temperature, vibration data

IoT Network Architecture

Elevator IoT devices live on a separate VLAN (we recommend VLAN 50). Internet access is restricted to the manufacturer's cloud (Otis One, KONE Care, etc.). No access to the IoT devices from the internal network — a one-way design.

Other IoT Sensors

• Remote water meters: LoRaWAN or NB-IoT, per-unit consumption tracking
• Heat/smoke sensors: Parking, storage, social facilities
• Door/window sensors: Social facilities, pool lockers
• Air quality sensors: Parking exhaust tracking (mandatory in new buildings)

All these devices must be strictly segmented to keep "Mirai"-style IoT botnet attacks from reaching the site network.

Common-Area Wi-Fi and 5651

If Wi-Fi is offered in common areas such as the lobby, pool, social facility, or children's playground, the 5651 obligations fall on the site management.

Obligations

• Access logs must be kept for two years
• User authentication (SMS code, resident's ID, etc.) is mandatory
• Logs must be signed and tamper-proof (TIB-approved logger or cloud service)
• You must be able to produce records within 30 minutes during an audit

Practical Solution

Cloud-based 5651 services make sense at site scale: a monthly cost of TRY 500-1,500, no hardware to buy, deployment in a few hours. A hardware logger is TRY 30,000-100,000 up front + annual maintenance.

For resident Wi-Fi, one-time authentication via Turkish ID or resident number; for guests, an SMS code.

Resident Data and KVKK

Site management processes residents' Turkish ID, name, address, contact info, property status, and payment data. Under KVKK it is the data controller.

VERBİS Registration Obligation

Site managements that meet certain criteria (employee count, annual revenue, etc.) are required to register with VERBİS. Failing to register carries the risk of administrative fines.

Privacy Notice

A privacy notice that lays out residents' rights and how their data is processed:

• Which data is processed (Turkish ID, contact, payment, camera, IoT, etc.)
• For what purposes (dues collection, security, legal obligation)
• How long it is retained
• Who it is shared with (the cleaning company, the elevator maintenance company, etc.)
• Residents' rights and the contact channel

Data Processor Agreements

The dues software provider, the camera cloud provider, the elevator IoT company — a data processor agreement must be signed with each of them. Otherwise, KVKK breach liability falls directly on the site management.
