Color LCD Multi-Touch Screen

The available color multi-touch screen provides convenient control and replay at the recorder's front panel. You can view the current status of each channel and each archive, receive visual and audible alerts, live-monitor multiple channels, and fully administer the system using the NexLog DX-Series Configuration Manager software. Playback functions available at the touch screen include quick replay, advanced search and replay, select calls to be protected, create incidents from groups of calls, add more calls to an existing incident, export an incident to USB, and burn the incident to CD.

Web-based NexLog DX-Series Configuration Manager Software

NexLog DX-Series communications recorders include the NexLog DX-Series Configuration Manager software, which permits secure browser-based access to system configuration parameters. NexLog DX-Series Configuration Manager software also allows the administration of password policies and assignment of each user's access permissions.

Call Evaluation and Reporting

The optional Eventide Quality Factor DX call evaluation software module allows supervisors to efficiently evaluate and score call-handling quality. Evaluation questions, answer banks, and skills can all be quickly entered and maintained, and the call evaluation forms can be created through a simple drag and drop process. The evaluation questions and forms can be quickly adapted for special incidents and changing requirements. Quality Factor DX software's reports are designed to help supervisors measure the quality of call handling and track performance.

Standard Reports

NexLog DX-Series communications recording systems include tabular and graphical reports that can be run at any time. These daily, weekly, and monthly reports provide managers with valuable information about call volumes and channel activity.
