1. Smart property overview
Smart property covers access control, repairs, energy, and security. Device data and work orders move over 4G. A PMS (Property Management System) holds work orders, energy, and access control in one place. Inspection means scheduled equipment checks with the record sent back. SimtoLink supplies property companies with 4G, a shared data pool, a private APN, and an API into the PMS.
2. Typical applications and connectivity needs
Smart property covers access control, repairs, and energy. Bandwidth and response time differ by job:
Repair work orders and inspections
The repair system and inspection terminals report work orders and inspection records over 4G for dispatch, progress tracking, and a satisfaction callback.
Energy monitoring and water and power meters
Water meters, power meters, and energy sensors report usage over 4G for household billing, anomaly alerts, and energy-saving analysis.
Access control and visitor management
Access readers and visitor terminals report passage records over 4G for face recognition, booked visitors, and blacklist checks.
Security monitoring and elevators
Cameras and elevator IoT devices report over 4G for video monitoring, trapped-person alerts, and maintenance reminders.
3. Core connectivity requirements
- Spread-out sites: Access readers, cameras, and repair terminals sit across buildings and estates, and most have no wired network. 4G is what covers them.
- Work orders and inspections: Repair systems and inspection terminals need a mobile link for dispatch, progress tracking, and a satisfaction callback.
- Energy and billing: Water meters, power meters, and energy sensors report usage for household billing and anomaly alerts. NB-IoT fits meters that report infrequently.
- Access control and visitors: Access readers and visitor terminals must check passage in real time and send the record, tied to face recognition and the blacklist.
- Platform integration: The PMS holds work orders, energy, access control, and security in one place, with an API that closes the data loop.
4. IoT SIM card comparison and recommendations
Devices differ in bandwidth and response time. Match the card to the device:
| Use case | Recommended standard | What matters |
|---|---|---|
| Access readers and visitor terminals | 4G | Passage records, face check, live reporting |
| Repair and inspection terminals | 4G | Work-order flow, mobile work |
| Energy meters and smoke detectors | NB-IoT / 4G | Infrequent reports, low cost |
| Security monitoring and elevators | 4G | Video upload, trapped-person alerts |
5. Data demand and usage
A device averages about 50-200MB a month, mostly video. Pool by residential community, keep a 20%-30% buffer, and use a private APN.
6. Security and compliance
The security level is medium. The link needs TLS/SSL, a private APN, and an IP allowlist. SimtoLink provides one-stop real-name registration.
7. SimtoLink recommended solution
For smart property, use 4G IoT SIM cards on access control, cameras, and repair terminals, and NB-IoT on energy meters, smoke detectors, and other sensors that report infrequently. Access control and cameras need live upload. Repair terminals need to work while staff are moving. The core advantages are 99.9% network availability, a shared data pool, and an API into the property management system.
8. Implementation guidance and best practices
Rollout steps:
Size the card to the community, confirm coverage inside the buildings, set the APN and allowlist, and alert at 80% of the data allowance. SimtoLink covers survey through daily operations. Contact us for a plan sized to the estate.
