When changing over and converting older Surveillance Camera Systems there is often the need to convert the voltage being used . Older systems Pre Digital Chip days which used tubes where mostly run using 24 Volts AC while almost all modern Analog and Analog HD systems use 12 volts DC power.
This means changing out the master power supply for all cameras if doing a full change out .
But what if it is only one camera you are changing?
That's where Voltage converters like the one made by MG Electronics makes sense
It converts 24 VAC to 12 VDC and is a great option for one camera being changed
However I recently encountered a dangerous situation where one of these units for unknown reasons melted down.
As you can see it started melting down and could have possibly caused a fire.
I have been in touch with manufacturer and not heard back from them yet.
But I suspect a power surge caused this as 24 VAC power to it was just a simple plug in transformer
with no filtering or regulation . But was plugged into a surge protected strip.
If your using these converters and see cameras stop working check it out you may have a problem.
