DETECTING THE INVISIBLE, FINDING THE IMPOSSIBLE with our Leakage and Ingress localizing solutions

Autonomous Recording Device ARD4

Autonomous Recording Device

The ARD4 autonomous recording device is the key component of CPAT FLEX. It pairs with our family of products to:

  • Manage GPS positioning in real time;
  • Record both egress and ingress events, and;
  • Upload egress and ingress data points to the CPAT WEB server for reporting and closing of work orders.

Do I need to install an ARD4 in all of my vehicles?

No, we have successfully demonstrated since 2005 that operators are not required to have ARD4s installed in 100% of their service/install vehicles in order to cover their HFC plant on a quarterly basis, as required by the FCC. The number of ARD4’s that must be installed depends on the density of the network plant to be patrolled (i.e.:urban, rural). 

Does the ARD4 lose the data collected if it does not upload to the CPAT WEB?

No, the unit has an internal memory that can store data up to 3 months’ worth of continuous patrol. 

How can I tell if the ARD4 is uploading data?

When the ARD4 has established connection with the FTP server, the COM LED will turn on green.

How can I tell if the ARD4 has uploaded the data?

Go to CPAT WEB, select  Reports, then select Module statistics,  and then select Egress report.
