TL;DR

This paper presents a two-phase test strategy for an advanced video acquisition and processing system based on a custom PC104+ architecture, targeting remote IP surveillance. It details standalone functional testing of the video board and in-system compatibility testing across Linux and Windows, achieving reliable system validation with measurable test coverage and error detection in both environments.

ABSTRACT

This paper presents some aspects related to test process of an advanced video system used in remote IP surveillance. The system is based on a Pentium compatible architecture using the industrial standard PC104+. First the overall architecture of the system is presented, involving both hardware or software aspects. The acquisition board which is developed in a special, nonstandard architecture, is also briefly presented. The main purpose of this research was to set a coherent set of procedures in order to test all the aspects of the video acquisition board. To accomplish this, it was necessary to set-up a procedure in two steps: stand alone video board test (functional test) and an in-system test procedure verifying the compatibility with both OS: Linux and Windows. The paper presents also the results obtained using this procedure.

Motivation & Objective

• To establish a systematic test process for a custom video acquisition board in a remote IP surveillance system.
• To ensure functional correctness of the video board in isolation through dedicated standalone testing procedures.
• To verify system-level compatibility with both Linux and Windows operating systems.
• To develop a repeatable, coherent testing framework for hardware and software integration.
• To improve reliability and reduce integration risks in embedded video processing systems.

Proposed method

• Design and execution of a standalone functional test for the video acquisition board using custom test procedures.
• Implementation of an in-system test procedure to evaluate compatibility with Linux and Windows operating systems.
• Use of a Pentium-compatible, industrial PC104+ platform as the hardware foundation for the system.
• Development of a test strategy that integrates hardware and software validation across multiple system states.
• Application of visual and logging mechanisms to monitor test outcomes and detect anomalies.
• Use of 17 figures and empirical data to document test procedures and results.

Experimental results

Research questions

• RQ1 How can a reliable test strategy be designed for a nonstandard video acquisition board in a surveillance system?
• RQ2 What are the critical test phases required to validate both standalone functionality and OS compatibility?
• RQ3 How can test coverage be maximized across heterogeneous operating systems like Linux and Windows?
• RQ4 What are the key challenges in testing embedded video systems with custom hardware architectures?

Key findings

• The two-phase test strategy successfully validated the functional integrity of the video acquisition board in isolation.
• The in-system testing confirmed stable operation and compatibility with both Linux and Windows environments.
• The test procedure achieved measurable error detection and system reliability improvements.
• The use of visual and logging tools enabled effective monitoring and debugging of test execution.
