Why Security-Grade Monitors Matter for Surveillance
Posted by Camille Chiu on
Posted on March 3, 2017 in Security Cameras Retail Security Quality matters when it comes to security camera monitors, and there’s a big difference between professional security-grade monitors and standard consumer-grade displays. You may think that a standard consumer-grade LCD monitor is acceptable for video security applications and will save you money. However, while consumer-grade displays do cost less, they are not designed to meet the rigorous demands of security applications. A cheaper monitor can quickly burn out with continuous use. 1. Designed for Continuous Use Consumer-grade displays are not meant to be used for more than...
HDTV (High Definition Television) and video surveillance
Posted by Camille Chiu on
Introduction The TV market is moving rapidly towards high-definition television, HDTV. This change brings truly improvements in image quality and color fidelity, HDTV provides up to five times higher resolution and twice the linear resolution compared with traditional, analog TV. Furthermore, HDTV comes with widescreen format and DVD-quality audio. Growth in the consumer market for HDTV is impressive. In 2007 the HDTV household penetration in the US was approximately 35 %. According to estimates, 85 % of all viewers will have an HDTV set at home by 2012. Already today, virtually all major television productions are HD. The two most...
The easy path to network video- Video encoders bring immediate benefits of IP-Surveillance
Posted by Camille Chiu on
1.The easy path to network video The introduction of network video has revolutionized video surveillance in many ways. 1. IP-based video surveillance systems bring many important benefits, such as vastly improved image quality, better scalability, event management, intelligent video and - in many cases lower cost of ownership. Nevertheless, it is too early to claim that this development has rendered all analog CCTV surveillance sys obsolete and useless. The technology shift does not force security managers to immediately choose between either an IP-Surveillance system or an analog video surveillance system. It is in fact possible to combine the two, thereby...
What's the difference between fixed lens and varifocal lens cameras?
Posted by Camille Chiu on
fixed lens camera, is a camera lens with a fixed lens which you can't adjust the focal length, angle of view and also level of zoom. but almost of all fixed lens cameras are wide angle and also smaller than varifocal cameras. varifocal lens cameras, is a camera lens with variable focal length in which focus changes as focal length (and magnification) changes, as compared to parfocal ("true") zoom lens, which remains in focus as the lens zooms (focal length and magnification change). Many so-called "zoom" lenses, particularly in the case of fixed lens cameras, are actually varifocal lenses. Usually the...

Some CCTV Cameras have IP66 some don't, What does IP66 mean?
Posted by Camille Chiu on
The IP rating system The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof. The rating’s first digit e.g. IP66 relates to the ingress protection against dust (6 means dust tight,...
