4-Channel AHD Recording
Supports 4-channel AV input with AHD 720P, 960H, D1 and CIF options, plus synchronized AV and VGA output directions.
The DST-9SD records up to four camera views, giving fleet teams a more complete picture of incidents involving buses, trucks and other commercial vehicles. Continuous local recording preserves video evidence even when mobile coverage is unavailable, helping operators investigate accidents, cargo damage and liability disputes with less reliance on driver recollection or a single camera angle. Optional Wi-Fi and 3G/4G connectivity make footage retrieval more convenient, reducing the need to remove SD cards from vehicles manually.
