Description
1. Product Overview
The DT-A86 is a versatile, compact, and rugged tester designed for CCTV professionals. It brings together every tool needed for testing, commissioning, fault diagnosis, and maintenance of surveillance equipment in a single handheld unit.
Beyond video and network testing, the A86 adds a high-precision digital multimeter and an optical power meter, so electrical and fiber measurements no longer require carrying separate instruments. Its data-logging and waveform-capture capabilities help technicians pinpoint equipment and line faults, including hard-to-catch intermittent issues, and significantly improve on-site troubleshooting efficiency.
Powered by an embedded Linux system, the A86 delivers smooth display performance and responsive operation for intensive daily use on job sites.
