Productbeschrijving
Dahua IPC-HDBW2441E-S IP-domecamera, ontworpen voor professionele videobewaking, met een resolutie van 4 MP (2688x1520) en geavanceerde WizSense-technologie. De 1/2,9-inch CMOS-sensor garandeert scherpe beelden onder alle lichtomstandigheden, dankzij een kleurweergave van 0,006 lux en 30 meter slimme IR.
Het beschikt over een vaste lens van 2,8 mm voor optimale hoekdekking en een ingebouwde microfoon voor het vastleggen van omgevingsgeluid. Het bevat geavanceerde functies zoals SMD Plus en perimeterbeveiliging voor mens en voertuig, wat valse alarmen vermindert en de systeemefficiëntie verbetert.
Dankzij de echte WDR van 120 dB biedt hij uitstekende prestaties in contrastrijke lichtscènes. De metalen behuizing met IP67 en IK10-bescherming maakt hem bestand tegen zware buitenomstandigheden. Hij ondersteunt PoE voor eenvoudige installatie en is uitgerust met een MicroSD-slot voor maximaal 256 GB.

New favorite
Format: Kindle
I have been working my way through KC Kean's series's and this is my new favorite! Raven is a magicless girl living in a wasteland. She is taken to a magical academy where nothing is as it seems, and her life is forever changed.
This is an original story with characters you can't help but love or hate depending on who you are talking about. There were no slow parts, the steam is at a perfect level, and I can't wait to start the next book.
Edit: Added after finishing the series. FYI Book 1 was AMAZING. Book 2 was not quite as good, but still worth reading. Books 3 and 4 really went downhill. If I had known, I don't know if I would have started the series.

Main Characters: Huntyr and Wolf
•
I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆
We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger!

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟
This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens.
The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him.
I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure.
My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times.
Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️
I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well.
Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on.
Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc?
However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy.
Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book.

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book.
I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.
