Development Scope
Device and interface access
Connect the camera or encoding equipment and clarify the video protocol, bit rate, resolution, video storage, and terminal heat dissipation and power supply.
Product business functions
Develop camera or encoding device access, cellular networking, video sessions, bit rate configuration, local recording and network interruption recovery.
Platform and data connection
Combined with the business link of image collection → encoding or local inference → video recording and evidence caching → 4G → video or event platform, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
Continuous video needs to verify the on-site uplink capability; when the network fluctuates, the bit rate, recording or session recovery will be adjusted as agreed, and fixed public network delay is not promised.
Data and Operational Workflow
Video capture and encoding → Local recording → 4G transmission session → Enterprise video platform → Viewing and record retrieval.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business process and parameters: encoding format, number of video channels, bit rate, video storage and on-site uplink.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Record the continuous upward movement of the target point and the picture conditions. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test disconnection, reconnection and video continuity. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Check access rights, session closures and traffic statistics. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
Can 4G support simultaneous uploading of multiple videos?+
It is necessary to comprehensively evaluate the bit rate, number of channels, encoding method and on-site continuous uplink capability. Projects can be divided into strategies based on real-time preview, local recording and event clip upload, and then multi-channel load testing can be performed.
Can I entrust only part of the functions of the video surveillance terminal?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing information and target boundaries, first check "encoding format, number of video channels, bit rate, video storage and on-site uplink", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking the encoding format, number of video channels, bit rate, video storage and on-site uplink; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
