Digital wireless camera. Wireless security cameras are closed-circuit television (CCTV) cameras that transmit a video and audio signal to a wireless receiver through a radio band. Many wireless security cameras require at least one cable or wire for power; "wireless" refers to the transmission of video/audio.
Samsung NX1 - First prosumer camera to record in HEVC, 4K downsampled from 6.5K, 80 Mbit/s in H.265. 30 min max recording time limit Samsung NX500 - Same 28 MP APS-C sensor as NXI but 4K video is not downsampled from 6.5K so less details and more noise than the NX1 - with this 2.4× crop factor the kit lens become a 38–120mm f8.5–13.4 ...
Early smart camera (ca. 1985, in red) with an 8MHz Z80 compared to a modern device featuring Texas Instruments' C64 @1GHz. A smart camera is a machine vision system which, in addition to image capture circuitry, is capable of extracting application-specific information from the captured images, along with generating event descriptions or making decisions that are used in an intelligent and ...
Extensive video surveillance systems were relegated to merely recording for possible forensic use to identify someone, after the fact of a theft, arson, attack or incident. Where wide angle camera views were employed, particularly for large outdoor areas, severe limitations were discovered even for this purpose due to insufficient resolution. [4]
The ARGUS-IS, or the Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System, is a Defense Advanced Research Projects Agency (DARPA) project contracted to BAE Systems. ARGUS is an advanced camera system that uses hundreds of cellphone cameras in a mosaic to video- and auto-track every moving object within a 15 square mile area.
Cameras using a CMOS Sensor, designed for faster auto-focus and low light capability. All cameras have optical image stabilization and can zoom optically while filming. DSC-WX1 (2009, 10.2 MP, no Manual mode, 5× optical zoom, G Lens, Sweep Panorama, HD Movie 720p) [ 75 ]
A wireless ad hoc network does not have fixed topology, and its connectivity among nodes is totally dependent on the behavior of the devices, their mobility patterns, distance with each other, etc. Hence, wireless mesh networks are a particular type of wireless ad hoc networks, with special emphasis on the resultant network topology.
The emergence of very high quality phone cameras since the early 2010s are making lower end, small sensor digital cameras redundant, almost as quickly as they grew the decade before in the 2000s. Consequently, manufacturers are focusing attention to premium models such as compact system cameras and large sensor compacts.
