Scenario development scope
Field devices and terminals
Focus on the development of 4G networked alarm panel, development of 4G water leakage alarm terminal and other products to clarify the interface, power supply and installation conditions, and develop or transform the terminal.
Business and data
Define data, events, commands and results based on field events or broadcast tasks → Local Status Processing → 4G → Enterprise Platform → Acknowledgment and Action records, retaining associations between devices, sites or projects.
Platform and operation and maintenance
Connect with existing enterprise platforms, or develop device management, historical data, alarms, permissions and client functions, and determine the scope by module.
system constraints
In the planning stage, check event levels, local alarms, notification acknowledgments, audio modes and lost contact prompts, and clarify the responsibilities and exception handling of local and remote systems.
product development services
Select corresponding technical services based on field equipment and target business. You can start with a single terminal or combine multiple device types. The following products describe the interfaces, business processes, delivery materials and acceptance methods respectively.
4G Connected Alarm Panel Development
For alarm equipment manufacturers, security integrators and site management platform companies, access wired alarm input or authorized wireless detectors, and develop a closed loop of disarming and disarming, zoning, event reporting, backup power supply and notification.

For broadcast equipment manufacturers, park integrators and distributed site operators, it develops audio reception, cache playback, grouping tasks, priorities, scheduled playback and playback result feedback.
View Development Scope and Deliverables →System composition and business process
On-site events or broadcast tasks → Local status processing → 4G → Enterprise platform → Receipt and disposal records.
The platform manages devices according to enterprise projects, sites and permissions. After the link is restored, check the data and service status; when control is involved, separately confirm command authority, timeliness, local conditions and execution feedback.
Project Inputs
- Target business, equipment list, on-site location, equipment size and users.
- Wiring, protocols, raw data and open software interfaces to existing equipment.
- Key confirmations: event level, local alarm, notification acknowledgment, audio mode and lost connection prompt.
- Platform status, data retention, client and deployment methods, prototype and on-site verification conditions.
Deliverables and Acceptance
| stage | Delivery content | Verification basis |
|---|---|---|
| Needs and plans | Equipment interface list, business process, system architecture and development division of labor | Check the event level, local alarm, notification acknowledgment, audio mode and lost connection prompt. |
| Development and integration testing | Agree on terminal hardware, firmware, interfaces and platform applications | Check the fields, status, instructions and abnormal behaviors one by one according to the actual device. |
| Acceptance and handover | Prototype or program, design and deployment data, test records and version list | Accept according to the agreed environment, sample, duration and threshold, and record the handling of failed items. |
R&D, prototype materials, structure, testing, on-site implementation and subsequent operation and maintenance are listed separately. Project cost and cycle are evaluated based on equipment type, interface complexity, existing foundation and verification workload.

View Development Scope and Deliverables →Frequently Asked Questions
Does the platform receiving an alert mean that someone has handled it?+
Event delivery, notification results, alarm acknowledgment confirmation and processing completion should be recorded separately. Define responsible persons and upgrade notification rules by business, and keep records of equipment recovery and manual disposal.
Can I reuse existing platforms and terminals?+
You can first check the existing interfaces, data and code, and focus new development on the missing links. In this scenario, it is necessary to focus on checking the event level, local alarm, notification acknowledgment, audio mode and lost connection prompt, and then determine the reusable scope and return work.
