"There are not enough books on electronic monitoring (EM) technologies and their uses in probation and prison contexts, so this is a welcome contribution. Clear explanations of EM technologies are provided to ensure readers have a decent understanding of what is being discussed . Daems is multi-lingual and incredibly well read, demonstrating a capacity for synthesising theoretical insights and international literatures into this short book in a way that is accessible and engaging." (Hannah Graham, Probation Journal, Vol. 69 (1), 2022) "Daems impressively manages to grasp the topic of EM in its entirety and explains it in a very understandable way. The book could be of particular interest to people who are interested in the topics of supervision and penology." (Melanie Schorsch, KULT_online - Review Journal for the Study of Culture, Issue 62, November, 2020) "The book is . an easy and quick read.

It is enough to make one think and ponder. I strongly recommend this book, for its style, creativity and thought-provoking nature. I had the impression that my thoughts on electronic surveillance, although the fruit of many years of legal and empirical research, had been spontaneously reshuffled and restructured. I also felt that the rationale behind 20 years of French EM developments appeared more clearly." (Martine Herzog-Evans, Journal of Probation, June 1, 2020).
