Productbeschrijving
De TPC-DF1241-B7F8-DW-S2 vaste camera met dubbele lens biedt een complete videobewakingsoplossing voor binnen en buitentoepassingen. De camera is uitgerust met zowel thermische als visuele beeldtechnologie en is ideaal voor het bewaken van kleine, donkere ruimtes. De serie combineert één thermische camera voor bewaking in volledige duisternis en één zichtbare camera met Smart IR-technologie voor het vastleggen van details.
De camera is uitgerust met twee beeldsensoren: een standaard 4MP CMOS met een effectief aantal pixels van 2336 x 1752 pixels en een ongekoelde VOx- microbolometer met een matrix van 256x192p. Dit maakt het mogelijk om alle objecten te observeren, zowel bij normaal zicht als bij mist, rook of volledige duisternis. De effectieve gebruiksduur van de thermische sensor is vrijwel onbeperkt, waardoor de camera ideaal is voor het bewaken van grote gebieden waar conventionele oplossingen geen adequate bescherming bieden.

Warning: You will want to read the classics after you read this book!
Format: Hardcover
This book beautifully captures what I didn’t realize was possible until I got to college: That the Lord can speak through great literature. When I was younger I largely avoided reading any fiction books because I felt guilty for not reading my Bible (but for some reason my apologetic books were ok? Lol). However, this book seeks to show (and I think accomplishes quite well) that great literature isn’t a hinderance to the Christian life but actually serves to cultivate a deep and thoroughly Christian imagination. Great literature has the capacity to convict you of your sins, to invoke worship and prayer, and to cultivate our desire to live lives of virtue. Great literature is a mirror through which you can examine your own way of life, but it also acts as a lens through which you can see with fresh eyes the world around you.
The author presents a lot of helpful practical advice in here too. Like how to know if a book is worth reading, different ways to approach reading books, as well as a thoughtful critique of the bad logic often used in Christian circles to avoid reading great literature.
“In a world that tries to convince us that we are computers or animals, that treats us like automatons or worker bees, what better protest than the reading life? If we are to be fully human, we must practice human acts— civility, creativity, contemplation, charity.”
All four of these acts are intertwined with reading great books! So let’s get to it!

A Book to Read and Read Again
Format: Hardcover
I finished this book a few days ago and have been obsessing over it in my mind ever since. Hooten Wilson (which is a delightfully fun name) is a brilliant scholar, excellent guide/teacher, and lover of Christ and the written word and all of that shows on every page.
This book is a call to look up from our screens and dive deep into the written word, both Scripture and literature. It is equal parts inspiring and practical. The robust and rich writing of the author is still easily accessible.
As one who grew up in love with books and reading, I moved to almost exclusively non-fiction in my adult years. This book inspired me to return to the beauty of fiction once again and to see the value of the written word as a way to love God, not just to gather and process information.
I will definitely be reading this one again.

Rich Academic Insight
Format: Hardcover
Near the beginning of "Reading for the Love of God," Jessica Hooten Wilson addresses why we should read fiction, responding to arguments in some Christian circles that we should only read the Bible. Other topics that she covers include the difference between using and enjoying books, how reading can help us develop greater virtue, and how we can rightly interpret books through the "trinity" of rightly balancing the text, the author's intent, and our own takeaways, instead of forcing the text to mean whatever we want. She also shares "bookmarks" between chapters about the reading lives of Augustine of Hippo, Julian of Norwich, Frederick Douglass, and Dorothy L. Sayers. These sections are thoughtful and encouraging, and the latter two are my favorite parts of the book.
There is a recommended reading list at the end that offers many wonderful selections, but I want to offer one quick warning. She includes the graphic novel adaptation of Octavia Butler's "Kindred" in her list for school-age readers, and although she mentions that it's more for the 10-12 age range, it is an adult book. The main character is an adult, and the graphic novel includes vivid on-page depictions of racial violence, attempted rape scenes, and a lot of talk about rape. Some older kids can handle that, but it would terrify others and was never intended for that age group.
Reading and the Bible
Hooten Wilson emphasizes that enhancing our reading skills through literature will help us better read, understand, and appreciate the Bible. She makes excellent points about how learning to read different literary genres will help with biblical interpretation, and she makes a convincing case for how practicing our interpretive skills and becoming more fluent with metaphor and other literary devices will enhance our experience with the Bible.
However, I felt that she sometimes went too far, making it sound like Bible-reading is an activity for the well-educated and well-practiced. God intended the Bible for everyone regardless of their socioeconomic class, abilities, or educational level, and even though reading the Bible badly can have negative consequences, this book focuses more on our own literary skills than the power of the Holy Spirit to reveal truth to us, convict us, and comfort us through Scripture. Hooten Wilson provides excellent next steps for people who want to deepen their relationship with the Bible, but I wished that she had articulated additional vital context around this.
Audience
This book is highly academic in content and tone, and even though I enjoyed this book and found it very enriching, it is only for serious readers. Hooten Wilson writes about highly abstract concepts in complex ways, and she often uses specialized vocabulary without explaining what she means. She also makes lots of references to monastic practices and obscure literary works that even highly bookish Christians are unlikely to be familiar with. This book shares rich scholarly perspectives, but it is not for reluctant or casual readers, especially since Hooten Wilson only acknowledges the worth of popular-level books in the special section on Dorothy L. Sayers.
It disappoints me that Christian books about reading are almost always written at such a lofty level that they are inaccessible to the people who need them most. I read hundreds of books every year, including dozens of academic ones, but I still felt that parts of the book were beyond me. If someone wants to begin getting more serious about reading, I would recommend Karen Swallow Prior's "On Reading Well" as a more accessible alternative with similar themes.
My other concern is that Hooten Wilson was always the expert in the anecdotes she shared, never the person learning something new. Only one anecdote bothered me in and of itself, and that is the chapter-opening illustration about a time when she set up an undergrad student for embarrassment to make a point during class. The other anecdotes don't involve power differentials and were perfectly fine, but taken together, they give the impression that the author needs to feel superior. I am sure this was unintentional, but I wish she had given examples of times that she lost an argument and learned something new.
Conclusion
Overall, I enjoyed "Reading for the Love of God," appreciating Hooten Wilson's unique insights and her scholarly perspective on the spiritual importance of reading. This book is deep and thoughtful, and there are a lot of important messages about reading great books to expand your mind, enhance your understanding of Scripture, and become closer to God. However, this book is so dense and academic that it is only for scholarly readers. I wish that this book could be an on-ramp for people who want to get more serious about reading, but it will probably just make them feel judged, lectured at, and so overwhelmed that they give up. This book has great value for people who inhabit the author's literary world or are so well-read that they can make the leap, but I hope that the she will consider ways to effectively reach popular audiences in the future.

Inspiration and affirmation of the richness of a reading life
Format: Hardcover
I listened to Hooten Wilson give a talk about the book and immediately pre-ordered it. It did not disappoint. I haven’t binge read a book like I did this one since last year with Abolition of Man. It was a delight to learn more about some extraordinary and diverse readers such as Julian of Norwich, Frederick Douglas, Dorothy Sayers and others. Hooten Wilson does an excellent job make a case for the ways reading both the Word and literature expands our capacity for living rightly and for reflecting God.
