Pan-tilt-zoom (PTZ) kamere su napravljene od mehaničkih delova koji im omogućavaju da se okreću levo-desno, naginju gore-dole i zumiraju i umanjuju scenu. Obično se koriste za nadgledanje širokih otvorenih područja za koje je potreban pogled od 180 ili 360 stepeni i raspoređeni su na stražarskim stanicama gde aktivno osoblje može da upravlja njima preko daljinskog kontrolera kamere. U zavisnosti od kamere ili softvera, takođe se mogu podesiti da automatski prate aktivnost izazvanu pokretom ili da se pridržavaju unapred postavljenog rasporeda. PTZ kamere se generalno implementiraju u tandemu sa većim sistemom za nadzor, u kojem PTZ prati kretanje dok fiksna kamera snima detaljne snimke.
PTZ IP kamera: PTZ internet protokol (IP) kamere se mogu primeniti preko WiFi ili Power over Ethernet (PoE). U poređenju sa tradicionalnim analognim PTZ kamerama WiFi PTZ kamera: WiFi PTZ kamere se bežično povezuju na ruter bez žičane veze. (Međutim, i dalje im je potreban izvor napajanja. ) Takođe se preporučuje jaka WiFi veza da bi se sprečili problemi sa kašnjenjem i kvalitetom videa.

Agile Practice Guide
Format: Paperback
Una muy buena compra para tener como guia repaso de los conceptos mas importantes de las metodologías agiles, y que variables tener en cuenta a la hora de encarar un proyecto y definir con que metodología se gestionará el mismo.
En un mundo en donde todos quieren IMPONER metodologías que todavía no entienden muy bien pero estan de moda, es una muy buena herramienta para entender cuando es valido hablar de metodologías agiles, de cuando hablamos de metodologías hibridas, o inclusive discutir si no es un approach mas eficiente el de ejecutar una metodología waterfall o lineal.
100% recomendado.

Excellent Introduction to SQL
Format: Paperback
I am compelled to share my overwhelmingly positive experience with the SQL Quickstart Giude which has proven to be an exceptional resource for anyone wanting to delve into the world of SQL coding.
First and foremost, the book is written in an extremely accessible manner, deftly simplifying complex concepts into digestible portions for beginners, yet providing deeper insights for seasoned developers. It transcends the barrier of technical jargon, presenting information in an intuitive, reader-friendly style.
However, the true selling point of this book, which separates it from the plethora of SQL resources available in the market, is the ingenious inclusion of its online resources. This addition enhances the book's value immeasurably, allowing the reader to step beyond the theoretical and put their knowledge into practice immediately.
The online resources that accompany the book provide a unique learning ecosystem, an ideal blend of theory and practice. They offer a plethora of well-organized and insightful coding examples for each chapter, which are also available for download. This allows the readers not only to work along as they learn but also to experiment and implement their own iterations of the code. This hands-on approach cements the concepts learned in a way that theoretical learning alone cannot.
Moreover, these downloads enable offline access, which ensures that you can learn at your convenience, a feature that not many SQL books offer. This aspect of anytime, anywhere learning is crucial in our current fast-paced world.
Furthermore, the author provides ample exercises to test your understanding, which are then complemented by detailed solutions on the online platform. This real-time feedback is instrumental in understanding one's progress and identifying areas for improvement, which paves the way for a confident and competent SQL programmer.
In conclusion, the "SQL Quickstart Guide" with its companion online resources has proven to be an unbeatable combination for learning SQL. It has created a learning experience that is seamless, engaging, and, most importantly, effective. It is a rare gem in a field often dominated by dense, inaccessible texts and I would highly recommend it to anyone wishing to embark or advance their journey in SQL programming.

Easy to follow, well written book. Can easily be used in liue of a textbook. Get spiral edition.
Format: Spiral-bound
Walter Shields does a fantastic job of writing this book from a perspective that a reader will have no clue on databases, or SQL. I'm a former Database programmer, but after being away for so many years I had to come back to SQL, and I needed a reference quick. Everything is written in a step by step easy to swallow informational way that leaves no room for failure. Even the examples are fantastic. This book is compatible with opensource SQL so need to pay for anything but the book.
Get the spiral edition, it lays flat on the table and is easier to follow.
Unlike McGraw Hill, Cengage, Thomson Course Technology, this book doesn't expire and block you from buying a used copy to prevent you from downloading the files needed to learn.
A fantastic reference, a great book, timeless because it doesn't expire.

SQL qsg book
Format: Paperback, Format: Paperback
I've taken a couple classes on SQL some time ago and was looking for a book to go over basics. This is a perfect book to start with the basics of understanding how to write a SQL query. I really liked that there is a free database to use in SQLite to follow along with the examples in the book. That was very helpful for me. I appreciated the tips throughout the chapters and the practice questions at the end. Easy to read and follow.

This is a good very distant overview
Format: Paperback
Sometimes I need a really simplistic overview of an entire subject before I feel comfortable sitting down to learn it. Like if you are going to learn about, say, 13th Century France you might want to know just a little about the major issues of the entire century before sitting down with a text book. This book is good for that. It's short, it gets you started with the main keywords, and at the end you have a good picture of what the language can do. And you can get to the end in a day or two. It's very well written, well organized, clear, and very very limited in scope. But if you read it, you will be in good shape to start getting down to business with working with SQL with a more advanced text. This book, in my opinion, was well worth the money and the read even though ultimately I turned to something far more advanced.
