Patlite NHV Signal Tower Light Application Examples

Application Examples


Application Example #1
A manufacturing warehouse has installed a new network camera configuration in their factory to monitor their equipment and for general security purposes. This type of camera setup requires an operator to physically arrive on-site to troubleshoot in the event the cameras stop working and require a restart. By equipping PATLITE’s new NHV Series network towers, the warehouse can automatically restart the camera by utilizing the remote power controller used to monitor the port. If the camera cannot restart automatically, the NHV Series will alert you of this activity via visual and email notifications. Additionally, you can send voice commands remotely to the NHV to audibly alert workers of equipment downtime, personnel arrival, and other unique commands via MP3 Playback. With PATLITE’s NHV Series Network Signal Tower with Voice Annunciator, you can confidently use network cameras.

Application Example #2


PATLITE’s NHV series signal towers can be used in call centers to reduce call wait times. This is done by using the signal tower to notify employees that there are calls waiting to be answered.

By indicating the operator’s call status with the NHV Series, administrators can monitor each situation remotely and in real-time, thus, in practice, reducing call long call wait times for its customers. Administrators can also send user-specific voice commands to the call center to alert workers with a "Text to Speech (TTS)" function on the NHV signal towers that converts text data to voice. This function makes it easy for the call center to create voice messages or read text messages aloud by typing text written by managers.

From email alerts to remote notifications and more, a busy call center can notify its personnel of call volume spikes by implementing PATLITE’s new NHV Series Network Signal Tower with Voice Annunciator.
