- См. comptroller
- An electric device (or combination of devices) designed to initiate one or more functions of operation, such as starting, stopping, reversing, and speed changing, of the apparatus to which it is connected; operation may be manual or automatic. control room, console room a small room, in or adjacent to an auditorium, having a view of the stage, in which the lighting or sound-control consoles are located. control set-point in an automatic control system, the point at which the value a control setting must be pre-set in order to achieve a desired value. for example, in an air-conditioning system, the set-point is the value of temperature that must be pre-set in order to establish the desired temperature in the conditioned space.
- Устройство управления
- Differs from comptroller, which applies chiefly to the duties of an accompt. but the controller of the navy controls naval matters in ship-building, fitting, &c. there is also the controller of victualling, and the controller-general of the coast-guard.

Motion detection, английский
Dvr: allows you to pre-define motion detection zones and sensitivity for each individual camera. when motion is detected by the dvr, this will trigger a pre-programmed event (usually a recording), or it can activate an external device, such as an alarm. this benefit allows you to save hard drive space by only recording relevant video in the areas you care about. it also saves time: you don t have to sift through countless hours of useless video where nothing is happening - you can quickly scan through the captured activity in the pre-defined area of coverage.
Digital noise reduction (dnr), английский
Digital noise reduction (dnr) technology offers several benefits. first, dnr delivers a cleaner signal, resulting in up to 70% disk space savings - so you can store more video evidence on your hard drive. next, cameras equipped with dnr technology deliver a more visually appealing image, making it easier to identify suspects. finally, dnr technology makes it easier for your camera to distinguish between true motion and image noise - allowing for your dvr to be more efficient in motion detection - especially in low light conditions. how it works: the chip in a camera is constantly picking up noise (fine static) in your images, especially in low-light modes. dnr technology compensates for this, correcting imperfections in the image by removing a large percentage of this noise. when a dvr or computer is processing the video data, it must compress and save every part of the image that is moving. the less noise in the image, the less data the dvr will save, and the more real motion it will detect.
