If you are looking, spy camera for your office, then you should choose the device according to the area of your working place. Normally people go for closed-circuit television (CCTV). It is a TV system in which signals are not publicly distributed, but are monitored, primarily for surveillance and security purposes,Mini,Video Audio CCTV camera is an example of a CCTV camera.
Progression is a way of smoothing out a picture. Usually, most such systems go with 30p (thirty frames per second, progressive rate), which is a video format that works well with cameras that capture imagery and then send them to LCD displays and most any sort of monitor, LCD or older cathode ray tube (CRT) included.
If a 30p capture card is used for 2 cameras, they’ll each be able to shoot at 15 frames per second and so on down, with more cameras added to the card input/output plugs. Really, there’s no need to use any faster or slower speed than 30p and the image needed for surveillance activities will be poorer if another FPS is used.
