Q:What do I need to do with video surveillance systems?
The monitoring system is composed of a large part of the camera, transmission, control, display, record registration. The camera transmits the video image to the control panel through the coaxial video cable, controls the host computer and assigns the video signal to each monitor and video equipment, and can simultaneously input the voice signal to be transmitted into the video recorder. By controlling the host, the operator can issue commands to control the up, down, left and right movements of the pan / tilt and zoom in on the lens, and can be controlled by the host in multi-camera and PTZ Between the switch. The use of special video processing mode, the image can be input, playback, processing and other operations, so that the video effect to achieve the best.
Q:What is the minimum illuminance indicator of the surveillance camera?
Therefore, the use of different F value of the lens, the camera's minimum illumination value of the determination will have a decisive impact. Second, the light source color temperature. The color temperature is an indicator of the light wavelength content in the light source. A 3200K light source is mostly between 600 nm and 900 nm, and a 9300K light source is between 300 and 500 nm, so the different color temperatures will change completely Test Results. On a typical CCD sensor, a light source with a wavelength of 600 nanometers will produce 10 times more electrons than a wavelength of 900 nanometers. This is why the color temperature is particularly marked for the meaning of the minimum illumination measurement results.
Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera? How far can its DC current output? Please have experienced master answer, thank you
General 2 * 1 power line transmission 300 meters is no problem.
Q:Hello, because no electric video recorder did not manually set, but I would like to look back a few days before the monitor can be transferred out
1, if the surveillance camera is only access to the monitor, no access to the hard disk video recorder, video images are not stored, you can only see the real-time picture, can not playback.
Q:What is the difference between a wireless surveillance camera and a cable surveillance camera?
Monitoring camera is a semiconductor imaging device, which has a high sensitivity, anti-glare, small distortion, small size, long life, anti-vibration and so on. Surveillance camera security system, the image generation is mainly from the CCD camera
Q:Home pinhole wireless surveillance camera where to sell? How much is the miniature camera?
Object-oriented is the decomposition of the composition of the transaction into the various objects, the purpose of the object is not to complete a step, but to describe a thing in the whole problem-solving steps in the behavior.
Q:Camera clarity, 1080p. 3mp. 4k, what does it mean
1080P that is 1920 × 1080 resolution, progressive scan (equivalent to two million pixels)
Q:Elevator in the monitor camera lens focal length with the number
The smaller the number of millimeters, the greater the angle, see the closer .3.6 mm angle of about 75 degrees, the proposed monitoring distance of 5 meters .2.8 mm angle of about 90 degrees, the proposed monitoring distance of 3 meters
Q:What is the meaning of monitoring the focal length in the camera?
Under normal circumstances, the fixed focus of the surveillance camera, the seller told the larger size, through the camera to see the target larger (that is, look far), but the narrower the angle of view (observation range), the shorter the depth of field. The smaller the size of the lens, the smaller the target (see near), the wider the viewing angle (the viewing range), the longer the depth of field.
Q:Monitor the camera what is the zoom
Zoom, is the focal length, that is, long-term problem! Is to see the camera to the object far, closer. Change is to see the object to enlarge. Do you understand that?
