In order to ensure much higher performance stability and reduce product defect rates, we have extended the machine's Aging Testing time to 16 hours before shipping which was 12 hours for former shipments.

That's why our recent order of mobile dvr and bus passenger counter system devices' lead time was extended to 5 days instead of 3 days, we hope all of our customers could understand and support this, thank you so much!

Sufficient time for testing will shorten the defect happening rate. We hope all the machines can work in stable and good operation!
