HD surveillance: Secrets to producing the best possible image quality

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...

Shedding light on integrated cameras and independent illuminators

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...

Tackling the challenge of low-light imaging for megapixel cameras

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 colour. 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 sta...

Enhancing security with 360-degree video surveillance

One alternative purpose for a 360-degree camera is the ability to provide a panoramic view in a wall-mounted orientation Surveillance cameras that capture 360-degree images are unique. However, cameras with technology that enables a user to retrospectively track an incident back in time are even more unique. This combination provides customers with total situational awareness—a field of view much larger than the capability of narrow-field, fixed-view cameras. In this art...
