Engineering Scope
The development of low-power time-lapse photography terminals is oriented to the usage requirement of "project sites need to record construction progress at low frequency", and the collection, processing, communication and power supply are designed as one set of products. The project can start from new main board development, existing firmware modification or designated module integration. The development scope is confirmed based on the target function, existing foundation and delivery requirements.
Interfaces and Product Integration
Develop shooting schedules, image storage, batch uploads, solar powered interfaces and remote configuration.
Power Supply and State Scheduling
Capture and store according to schedule, transfer centrally at designated times, and adjust non-critical tasks based on battery power.
Data and System Integration
Clarify connections and data formats around cameras, RTC, storage, solar interfaces and communication modules, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form schedule firmware, image management, remote configuration and daily energy statistics, focusing on verifying the number of shots throughout the day, energy storage without light, upload window and configuration effective time.
System Architecture and Operation
Capture and store according to schedule, transfer centrally at designated times, and adjust non-critical tasks based on battery power.
- Interface composition: camera, RTC, storage, solar interface and communication module.
- Work scheduling: Determine each status based on sampling, interaction and reception requirements, indicating which circuits continue to run.
- Exception handling: Define deadlines, bounded retries, and recovery behaviors for applicable communication, sensing, or execution tasks.
Design Conditions and Functional Limits
The length of time without light and the shooting plan need to determine the energy storage capacity together.
Define power targets together with functional requirements. Battery-life estimates must specify the battery, temperature, operating cycle, event frequency and network conditions. Keep estimates separate from continuous-operation test results.

How does the equipment operate when it rains for many days?+
Define mission and low-battery thresholds that must be retained by project, assess the business impact of reducing non-critical uploads or shots, and verify mission status after energy storage is restored.
Is it possible to develop only part of an existing product?+
Module development or power consumption optimization can be carried out according to the existing interface and modifiable range. For this product, you first need to check the camera, RTC, storage, solar interface and communication module, and then determine the scope of changes and regressions.
How to determine the cost and period of this project?+
The evaluation is split based on the delivery items such as schedule firmware, image management, remote configuration, and daily energy statistics; the prototype materials, structure, platform, external tests, and new functions are listed separately, and quotations and nodes are formed after the requirements and interfaces are confirmed.
