4: Maintaining and Troubleshooting the S2800e

Verint Video Intelligence Solutions 44

Updating the Firmware

You may need to update the S2800e to have access to new firmware or new features.

Updating the firmware of a device retains its configuration. To perform the update, use

Nextiva Control Center; for the procedure, refer to the Nextiva Administrator Guide.

The latest firmware files are available on the Verint Video Intelligence Solutions extranet

(Quick Links > Firmware and Applications > Nextiva Intelligent Edge Devices).

Troubleshooting the Camera

If the S2800e does not power up correctly, check the following:

 Check if the DP2 power LED on the interface board is on. If the voltage is too low, the

LED will stay off.

 Check with a voltmeter that 18–32V AC is measured across pins 1 and 2 of TB1. If not,

check the integrity of the power wiring. If less than 18V AC is measured, it is probable

that the power cable length is too long. If 18–32V AC is measured, return the S2800e

back to factory for service.

In Nextiva Review, if the heads-up display (HUD) overlay does not appear after clicking the

Show PTZ Toolbar button, check if the video card is supported. The list of supported video

cards is provided in the TN_5.1_004 Video Card Support in Nextiva Review technical note,

available on the extranet (Community Links > Technical Notes - HotFixes - Rollups >

Nextiva 5.1).

Maintaining the Lower Domes

The S2800e requires no scheduled maintenance; however, the lower domes require

occasional cleaning and careful handling.

 Always handle the lower dome by the flange and avoid touching the inside surface.

 Use clean dry pressurized air to remove dust or dirt accumulated in the interior of the

lower dome.

 Remove spots, streaks or stains appearing on the interior or exterior of the dome with a

solution of 50% isopropyl alcohol and 50% water using a soft microwave-safe

(aluminum free) paper towel. Dry with clean, dry pressurized air.

 Clean all surfaces with any soft, non-abrasive cleaning cloth and a cleaning agent

suitable for acrylic plastic.

Note: Firmware downgrade is not supported on any device. If you perform a downgrade,

any problem encountered will not be covered by your product warranty.
