 More Information: 

【4K Ultra HD - 8MP Resolution】 4K means there are over 8 million pixels which are more than 4X the number of pixels of Full HD 1080P. It results in vivid resolution, sharper video, and realistic color representation and makes the faces, license plates, details, and close-ups much clearly during the day and night time even when you digitally zoom into far away objects. With Elder 4K security camera system, you'll experience the difference that 4K resolution (3840 x 2160) makes when it runs to your surveillance system.

【Color Night Vision, Full-Color NV】 Elder security camera system color night vision allows you to get full-color images even in extremely low-light conditions with the state-of-the-art spotlight night vision technology. Full-Color Night Vision technology brings you a higher level of security and enhances image qualities in the nighttime.

【 DIY Easy Installation, Plug-&-Play】 Elder security camera system is a real plug-&-play DVR surveillance system! Only a cctv cable (included) is needed for the connection between the camera and the DVR for video, power, and audio. A plug-&-play connection makes it simple to set up and install your DVR security camera system, especially for beginners and fans of DIY (Do-It-Yourself) security systems.

【Intelligent Detection & Smart Playback】 Thanks to this innovative feature, you will get an immediate push notification to your smartphone via its smart app whenever a movement, a person, or a vehicle is detected on your home & property. So, you can act immediately to prevent unwanted activity. You also can customize the detection zone from your DVR to effectively reduce the number of unwanted false alarms. With smart area playback technology, you can select a specific area of the image to automatically search for movement within recordings.

【Built-in Mic & Listen-in Audio】 The Elder cameras come equipped with built-in microphones that allow for crystal-clear audio. It features Audio-over-Coax technology, which means the audio and video will be transmitted over a single coaxial cable. An audio recording would enhance the security coverage and add a significant new feature to your security system, as you will have recorded videos with clear audio and voice. 

【H.265 / HEVC Video Compression】 This advanced encoding technology compresses video file sizes without sacrificing any quality which improves bandwidth efficiency, saves hard drive storage space and reduces storage costs. This new type of encoding can save up to 50% more space when compared to conventional H.264, so the hard drive could record for a much longer time with H.265 recording technology.

【HDD Storage All-Day 24/7 Recording】 With a pre-installed security-grade hard drive, users are provided continuous 24/7 local recording and all-around protection for home & business without any additional costs or subscription fees. Elder DVR has the possibility of increasing local storage space up to 8TB. You can also backup and transfer the desired playbacks from stored videos to a USB memory or external hard drive. Elder DVR automatically overwrites the oldest internally stored footage.

【Weatherproof Heavy-Duty Housing IP67】 This system’s cameras are suitable for anywhere, outdoor or indoor installation. The weatherproof rating and heavy-duty exterior add extra protection against vandalism and harsh weather, providing you truly year-round protection. Elder weatherproof cameras can withstand pretty much anything, such as snowfalls, rain, dust, heat, and wind, all year round.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

An absolute must for everyone dabbling with Unity 6 Game Development
Format: Paperback
Half of this book is about C# (until Chapter 6), and the other half is about actually making games. The book is very well written, and it is everything I needed to get a few problems solved with Unity 6 projects. I love how clearly things are explained, and the only thing I wish for is that I was able to spend more time delving into this while maintaining my financial status...

A Seasoned Developer's Fresh Perspective on Game Development
Format: Paperback
Finally, a game dev book that respects your existing programming knowledge As someone who's spent two decades architecting enterprise web applications in C# and ASP.NET, I approached game development with what I thought was a solid foundation. I was wrong—not about C#, but about how differently it's applied in game engines. After five frustrating years of trying to bridge that gap through scattered tutorials and documentation, Harrison Ferrone's eighth edition finally gave me the structured path I needed. What This Book Gets Right for Experienced Developers: The pacing is deceptive. Yes, it starts with programming fundamentals, but don't skip ahead. Ferrone's approach to OOP in the context of Unity's component architecture was revelatory. In web dev, I'd been writing services, repositories, and dependency injection for years. Here, the MonoBehaviour lifecycle and component-based thinking required a genuine mental shift that the book handles exceptionally well in chapters 5-6. Chapter 10's revisit of types and methods isn't redundant—it's strategic. By this point, you've written enough Unity scripts to appreciate why game code patterns differ from traditional enterprise patterns. The discussion of value types vs reference types hits differently when you're optimizing frame rates instead of HTTP response times. The Unity 6 Update Matters: Having struggled with outdated Unity tutorials for years, the Unity 6-specific content is invaluable. The screenshots are comprehensive (full-screen mode can make text small, but the GitHub repo and graphics bundle solve this). More importantly, the code samples reflect current Unity APIs and best practices, not deprecated approaches that still litter Stack Overflow. Where It Shines for Career Transitioners: Chapters 11-13 are worth the price alone. LINQ in Unity isn't just about querying collections—it's about performance considerations I never had to think about in web apps. The coverage of generics, delegates, and events finally connected how Unity's event system relates to patterns I already knew, but in a real-time context where every allocation matters. The serialization chapter (12) bridged my understanding of data persistence from databases and JSON APIs to Unity's PlayerPrefs and ScriptableObjects. This practical grounding is what most tutorials skip. Minor Quibbles: The FPS prototype is solid for learning, but I wish there was more discussion of common anti-patterns experienced developers bring from other domains. I still catch myself over-engineering solutions when Unity's component system offers simpler approaches. Also, while the book touches on performance, those coming from async/await-heavy web development will need supplementary resources on Unity's coroutines and the Job System for more complex scenarios. Bottom Line: If you're a professional developer trying to break into game development, stop collecting random Udemy courses. This book provides the structured progression and context-appropriate examples that respects your intelligence while teaching you to think like a game developer. The C# you know is necessary but not sufficient—Ferrone bridges that gap methodically. After years of false starts, I finally have a working game prototype and, more importantly, the mental models to keep building. That's worth significantly more than the cover price. Disclosure: I received an advance review copy from Packt Publishing. This honest review reflects my genuine experience as a career-changing developer.

A Worthy Touchstone for Anyone Who Wants to Master Unity
Format: Paperback
Harrison Ferrone’s Learning C# by Developing Games with Unity 6 is one of the strongest beginner-to-intermediate Unity guides I’ve read: carefully structured, patient in its explanations, and quietly packed with insight about how Unity 6 and C# truly work together. I read the physical edition while sitting in front of a blank Unity project, and the experience felt like having a seasoned sailor point out the currents of a river I’ve been navigating for years. You see the familiar terrain differently. The book’s early decision to spend real time on C# fundamentals is a welcome choice. Most Unity books skip past the language; Harrison slows down, defines concepts, and gives you enough clarity that when you finally enter Unity, you understand why things behave the way they do. Those chapters are dense in the best way: they prep beginners to stand on solid ground and give experienced users a clean, refreshed mental model of the language under the engine. Ferrone’s real strength is his voice. He strikes a balance I rarely see in technical writing: conversational introductions that explain what you’re about to learn and why it matters, followed by crisp, accessible technical walkthroughs. The pacing (explanation → example → implementation) is excellent. And the inclusion of ready-to-use assets removes one of the biggest barriers for new developers who want to understand systems without getting lost creating placeholder art. The book doesn’t talk down to anyone. It makes Unity feel more accessible without flattening its complexity. Beginners will come away with genuine competence; advanced users will appreciate the clear framing of new Unity 6 tools and the subtle recognition of how AI-assisted coding is shaping modern workflows. It’s a guide you can read once for understanding, then keep at your desk as a reference. If you’re a serious hobbyist, a technically inclined beginner, or someone who’s ready to work through your first real project, this is the Unity book I’d hand you first. It bridges concept and execution with clarity and confidence, and it does so with a tone that feels patient, practical, and quietly encouraging. In a space crowded with copy-paste tutorials, Harrison Ferrone has written a Unity 6 guide with real staying power.
