These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
Wireless security cameras function best when there is a clear line of sight between the camera(s) and the receiver. If digital wireless cameras are outdoors and have a clear line of sight, they typically have a range between 250 and 450 feet. If located indoors, the range can be limited to 100 to 150 feet.
The Nikon 1 series used Aptina sensors with dual conversion gain sensors, allowing users to choose from a mode with high dynamic range (DR) but low ISO, and a low light mode with low read noise but also less DR. [12] In 2014 the company started offering a 1-Inch 4K Image Sensor for security and surveillance cameras. [13]
DSLR cameras often have image sensors of much larger size and often higher quality, offering lower noise, [50] which is useful in low light. Although mirrorless digital cameras with APS-C and full frame sensors exist, most full frame and medium format sized image sensors are still seen in DSLR designs.

This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors. Some cameras use a larger sensor including, at the high end, a pricey full-frame sensor compact camera, such as Sony Cyber-shot DSC-RX1, but have capability near that of a DSLR.
Until the development of SLR, all cameras with viewfinders had two optical light paths: one through the lens to the film, and another positioned above (TLR or twin-lens reflex) or to the side (rangefinder). Because the viewfinder and the film lens cannot share the same optical path, the viewing lens is aimed to intersect with the film lens at a ...
Lytro Illum 2nd generation light field camera Front and back of a Lytro, the first consumer light field camera, showing the front lens and LCD touchscreen. A light field camera, also known as a plenoptic camera, is a camera that captures information about the light field emanating from a scene; that is, the intensity of light in a scene, and also the precise direction that the light rays are ...
