Productbeschrijving
De SD4A216DB-HNY high-speed netwerkcamera is uitgerust met een 1/2,8" STARVIS CMOS-beeldsensor, die hoogwaardige beelden levert met een resolutie van 2 MP (1920x1080). De lens, met een brandpuntsafstand van 5 tot 80 mm, biedt 16x optische zoom. Een ingebouwde infraroodstraler met een bereik tot 100 meter maakt nachtbewaking mogelijk. De camera beschikt ook over diverse signaalverwerkingsfuncties die ruis verminderen en de beeldkwaliteit verbeteren, zoals WDR120dB, AGC, HLC en BLC. De IP66-geclassificeerde behuizing en het brede temperatuurbereik maken het mogelijk om de camera te gebruiken in zware omgevingsomstandigheden.
Apparaten uit de WizSense-serie zijn onder andere voorzien van kunstmatige intelligentie (AI) op basis van deep learning-algoritmen. Ze beschikken over geavanceerde beeldanalysefuncties gericht op mensen en voertuigen. Deze intelligente en uitgebreide oplossingen detecteren potentiële bedreigingen met hoge nauwkeurigheid, wat de beveiliging verbetert.
De camera wordt aangestuurd via een IP-netwerk en is compatibel met de meest gangbare communicatieprotocollen. Automatisch protocol Herkenning maakt apparaatconfiguratie snel en efficiënt.
Uitgebreide bedieningsfuncties maken onder andere het volgen van objecten mogelijk, het programmeren en oproepen van presets, het creëren van patrouillepaden en bewegingsroutes, het terugzetten van de camera naar een geprogrammeerde taak na een bepaalde periode van inactiviteit van de gebruiker (Idle Motion), en meer. Het aanpassen van de bewegingssnelheid aan het zoomniveau, het Auto Focus-systeem en het Auto Iris-systeem maken de camerabediening eenvoudig en plezierig.

🙌 body diversity 🙌
Format: Kindle
Body diversity for the win in this new twist on a classic vampire x human trope! A Rose For The Taking explores the arranged marriage between an under-appreciated “spinster” and a vampire magistrate stuck in her own grief. Beyond the budding romance, we are also given a piercing look into the struggle of vampire/human politics including classism, worker exploitation and policy reform. The spice was sparingly scattered throughout the book and was unfortunately almost exclusively one-sided…which continues to be my biggest pet peeve in these books. Overall, the steamy bits were effective and blended well into the storyline. No kink, mostly open door. Additionally, Trapp lovingly incorporates a realistically proportioned FMC, the grief of losing a spouse and the familial trauma of being tolerated only for what you bring to the table. Solid read and it definitely got me adding more of Trapp’s body of work to my TBR!

It was a good read.
Format: Kindle
While I did enjoy the book, it moved a little fast with little plot development. Rose started strong and then she seemed to get weaker and weaker throughout. Even the parts where she found her back bone didn’t compare to her initial anger towards her family.
Lena was a good character. A little huffier than I liked but overall well rounded. Overall, I enjoyed the book, it just wasn’t my favorite.

Lovely sapphic vampire and human romance!
Format: Kindle
I was given an ARC copy of A Rose For The Taking by author Katie Trapp. Thank you Katie for the chance to be an ARC reader.
A Rose For the Taking is a sapphic vampire and human romance with topics of arranged marriage, self-discovery, and a little bit of mystery. Rose is a human, who is pressured by her family to enter an arranged marriage with a vampire, Lina. Lina is a vampire whose job is to maintain the peace between vampires and humans. With tensions rising between the two Lina agrees to marry a human in order to hopefully ease those tensions. Lina chooses Rose expecting to be friends, but nothing else. Instead love starts to blossom between the two as Rose learns to find her inner strength and stand up for herself, while Lina learns to open up her heart again. However, a threat causing the tension between the humans and vampires puts there love at risk as well.
The journey these two characters take is so relatable. Rose has been taught by her family to be subservient and basically have no voice. Lina has grown closed off in terms of romance due to her past experience. Together they go through a process of self discovery and fall in love during the process. They aren't perfect though with some ups and downs, which makes this story even more relatable.
This book has it all. There is growth of characters finding themselves, a spicy romance, and a little bit of mystery that blended together creates a story you don't want to put down till you finish it. I have read a few of Katie Trapp's books so far and each one has captured me in some way and just drawn me in. Katie has a way with words that you can somehow relate to the characters in one way or another. This one was no different and I enjoyed this book a lot. If you like vampire and human romance this is the book to read. I look forward to Katie's next book.

Ford.Grant. That is all
Format: Kindle
Umm ok so this was literally the most PERFECT thing. This book is special. These characters are special and beautiful, and so wonderful. So precious. I love them all. I love this book. I'm blown away.
You know those rare books that enchant you from the very first sentence, the ones that grab your heart and don’t let it go? THIS. This is one of those books. I adore this book with my entire heart. It was so utterly perfect in all the best and right ways. I honestly just wish I could go back and read this again for the first time because it was SO GOOD.
I devoured this in two days and was just absolutely giddy while reading about Ford and Rosie’s love story. I swear, Elsie Silver wrote my love language with these two. The sarcastic and witty exchanges between them is what I absolutely loved and couldn’t get enough of. Their attraction towards one another and the fact they were so clearly head over heels in love was undeniable and the tension between the two of them was so palpable that it gave me all the feels. My heart absolutely ached for these two, even when I was literally laughing out loud over their banter. And boy, the way they loved each other just swept me off my feet in my most favourite way.
I don’t know what my favourite part of this story was. There isn’t just one. There’s many. It’s all of it. There’s so much to it that if I was to really dive into it, I’d come out with an essay. All of that to say, I loved it. I really, really loved this story. Soul level and all the good stuff. I cannot say anything bad about this book. It’s up there as one of my all-time favourites and I love it with every fibre of my being. A million hats off to Elsie Silver for this one, because I know this is a story I’ll be thinking about for a long time. Elsie Silver can truly do no wrong. She is the blueprint, and I will read her books forever.
