I noticed at the end of the book a section discussing Backup Power for Large Security Systems. I am disappointed the time I spent in 2016 correcting the errors in an article about utility power backup was apparently wasted, as none of my corrections made it into this book.
As I wrote then,
The article says,
* Each Distribution Panel Supplies 11 cameras * Each Camera consumes a maximum 15 Watts * Cameras need to work for at least 8 hours on backup power. * (11X15=165W/h * 8 hours =1320 W)
Saying 165 Watts/hour is nonsense considering what is mean to be conveyed: The unit Watt is the rate of using energy.
 Technically speaking the 1 Watt = 1 Joule / second
I then went through the article correcting the terminology and units, showing the cost of the generator option was reduced and the conclusion reached could have been different.
