Many end-users shell out the cash to acquire the newest high-end devices, plug in, and expect to be wowed A well-developed surveillance system can give a single security guard the power to see what otherwise might take a hundred pairs of eyes to see. But what happens when all the components are all connected and powered up, and the resulting image on the screen is, well, indiscernible, or, at the very least, terribly pixelated? Many end-users shell out the cash to acquire the...

Lighting, or the absence of it, is one issue that significantly affects a camera’s video quality Video surveillance has rapidly advanced over the last two decades. Today, integrators can purchase IP cameras offering complete network control, megapixel cameras with HD imaging, and PTZ cameras with remote directional control. Although these features are impressive, they don't solve all the challenges that surveillance solutions face. Importance Of Lighting For Camera Per...

A bright, high quality lens, a responsive high sensitivity sensor and great imageprocessing produce a good low light performance  If you’ve been to any surveillance trade show, or picked up an industry magazine in the past few years, you will have noticed that almost every camera manufacturer seems to be talking about low light. Some have specific, dedicated low light products with named technologies, while others claim low light capabilities across their whole prod...

Low-light imaging has historically been a problem for megapixel cameras. Arecont Vision, like other megapixel camera manufacturers, has struggled to solve the dilemma of low-light images, which are plagued by noise, smearing of video, high bit rates (requiring additional storage) and loss of color. Arecont Vision says it now has the answer, dubbing it STELLAR technology. The “LL” in the middle of STELLAR stands for “low-light;” the entire acronym stan...

One alternative purpose for a 360-degree camera is the ability to provide a panoramic view in a wall-mounted orientation Changing security requirements have necessitated rapid advances in video surveillance technologies.  With the ability to retrospectively track incidents of security breaches, 360-degree cameras provide a much clearer perspective into such events. Here, Richard Pineau of Oncam explains the many facets of this technology and its impact on improv...

Ambient lighting in hospitality environments pose major challenges for video surveillance Variable lighting conditions pose a persistent challenge in video surveillance applications such as large retail locations, banks and financial institutions, and hospitality environments.Challenges to lighting quality Typically, retail locations, banks and hospitality venues include an abundance of windows. The resulting excessive light can damage video image quality, by flooding the ima...
