Higher Power PoE 802.3bt Ratified, Impact on Security Products Examined
Power over Ethernet has become one of the most popular features of many video, access, and other security products. See our PoE for IP Video Surveillance Guide and PoE Powered Access Control Tutorial.
Now PoE is able to transmit even more power, with the new standard boasting:
the newly ratified specification increases maximum power levels supplied by a factor of three.
But how impactful will the increase be for security?
Inside this note, we explain:
- The new classes and levels of max power delivered
- PSE vs PD power availability
- Impact on cameras
- Impact on switches, NVRs and monitors
- Potential for PoE lighting and Display Signange
