Historically, UL listings for central stations have been important, with UL 827 having widespread support.
However, few central stations have adopted UL 827B, the companion listing for managed video, which debuted in 2015.
In this note, based on our interviews with UL, and monitoring stations that have obtained 827B listing as well as those who have not, we examine:
- Who has UL 827B certification?
- The key differences between UL 827 vs. UL 827B
- Pro case for 827B
- Con case for 827B
- Getting 827B certification
- Certification timetable
- Up-front and recurring costs
