Snmp short message

I've seen this kind of thing in Japan before, but it seems that I can't notify the problem through voice broadcast. Recently, I saw a similar product in the domestic IT market, which should be called the black cat detective network acousto-optic alarm lamp. I have a general understanding of this kind of alarm lamp, and its performance is better than what I have seen before. It has the function of SNMP trap alarm and can send out audible and visual alarm. When problems are found, the operation and maintenance personnel can be reminded to solve them in time by turning off the lights and voice. You can learn about it.
