Dahua’s Analytics+ technology introduces the latest innovations in highly accurate perimeter protection. The technology enhances the tripwire and intrusion detection functions by including an object filter, a highly accurate way to distinguish between people and vehicles. Objects that cross a defined line can be categorized as humans or motor vehicles, making incidents easier to search […]

Application: You need to install a camera in the lobby of a building to capture the entrance area. Problem: The application has a lot of windows which over exposes the image making it difficult to capture who is coming and going. Solution: A security camera with good Wide Dynamic Range (WDR) is a solution to […]

Deciding what camera resolution is right for your application isn’t complicated, but it can be confusing if you’re not familiar with best practices. Here are three quick steps to make sure your video surveillance system is capturing the needed detail in a scene, without incorporating pricey high-megapixel cameras your customer doesn’t necessarily need. Finding DORI […]

The increase in security measures in educational environments brings new challenges. These include maximizing the benefits of video surveillance and addressing privacy concerns, while keeping the safety of students, faculty, and staff a top priority. Though challenges evolve, technology is evolving too. Artificial Intelligence (AI) is powering a new generation of advanced, highly effective, security […]

Can you define AI? What about deep learning and machine learning? These words are being used a lot lately, and they can be confusing. Here, we give you a breakdown of what each of these terms mean and how they are being used in video surveillance. Artificial Intelligence (AI) The concept of artificial intelligence has [...]

H.264. H.265. You’ve heard those terms, and you’ve probably heard of Smart H.265+ as well. But do you know what differentiates these video compression codecs and why you might want to choose one over the other? We’ve put together a quick guide to understanding the benefits. Save on Storage Costs When spec’ing a video surveillance [...]

Calling all tech geeks! We know that some of you are curious about how, exactly, Dahua’s optimized video compression codec, Smart H.265+ works. Here are four innovative things it does to reduce bitrate and storage requirements. Scene-Adaptive Encoding A typical surveillance scene is not fixed; the scene is constantly in flux even though these changes [...]

Pan Tilt Zoom (PTZ) cameras are useful because they can pan, tilt, and zoom, of course, but some models also have innovative features that take your security system to the next level. Test your PTZ knowledge with this quiz. True or false: IR illumination is always ineffective on PTZs because the zoom distance far exceeds [...]

Determining what kind of lens to use in a security camera isn’t as difficult as it once was. Because the majority of security cameras today have an integrated, matched lens, a lot of the guesswork has been taken out of lens selection. Yet integrated-lens cameras still require interpretation of conditions specific to the security application, [...]

Video surveillance in dark conditions is imperative for many users, since crimes like burglary and vandalism are more likely to occur at night. It’s easy to deploy a cost-effective security solution that can provide clear images in low-light situations, thanks to innovations such as infrared (IR) and Dahua’s Night Color Technology. White Light LEDs Sometimes [...]
