Q:Ask the professional to answer, monitor the camera with water ripples

To distinguish between power problems and ground loop problems, an easy way is to control the host, the nearest access to a power supply without a problem camera output signal, if the monitor does not appear on the interference phenomenon , Then the control host no problem. Next, you can use a portable monitor near the video output of the front-end camera, and check each camera one by one. If so, then processed. If no, the interference is caused by ground loops and other reasons.

Q:What is the difference between a camera and a monitor?

You said the difference between the "camera and monitor", that is, family (professional) with the camera and monitor the difference between the camera, their biggest difference is the family (professional) with a camera with viewfinder (LCD or electronic images ) And the storage system (hard disk memory, flash memory, tape memory), and the monitoring camera does not.

Q:What is the minimum illuminance indicator of the surveillance camera?

IRE Level: The maximum amplitude of the video output of the CCD camera is generally set at 100IRE (or 700 mV), and a 100IRE video indicates that you can fully drive a monitor to show the best brightness and contrast image quality. 50IRE video shows only half the contrast, 30IRE (or 210 millivolts) that only 30% of the original amplitude, usually 30IRE is the lowest performance available image value. So there is no indication of the lowest illuminance results of the IRE grade and are not actually comparable. Finally, it is the camera's special function settings.

Q:Monitor camera parameters how to see

Field of view: In engineering practice, we often use the horizontal field of view to reflect the shooting range of the screen. The larger the focal length f is, the smaller the viewing angle is, and the smaller the screen range is formed on the photosensitive member. On the other hand, the smaller the focal length f is, the larger the field angle is, and the larger the picture range is formed on the photosensitive member.

Q:What kind of monitoring camera is used in the store? 360 ° with the introduction of ordinary

If you require a higher, such as your shop to buy something slightly worth it, it is recommended to use the network HD, or cable through the HD, the resolution of this device is 4 times the normal, of course, the price is more than 1 times higher.

4. Infrared camera, this camera in the case of light enough for the color, in the absence of light and light dark case, the infrared light to open, to black and white monitoring. Applicable to Internet cafes, underground passage, garage and other dark places.

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 does it mean to monitor the camera channel?

Channel refers to the physical location of the video input of the camera on the monitoring matrix or the DVR device. Such as: ordinary hard disk video recorders support 16 video signals, so that the back of the hard disk video recorder has 16 video input interface, the channel refers to the physical location of these video interfaces, generally from left to right sort.

Q:Monitor the camera has a video port, what is this mouth, then what machine, direct access to the TV can you?

Is BNC port, direct access to TV no problem, then the old TV video line is a BNC, one is the Lotus head, then LCD TV two are BNC; only the camera directly to the TV, then only on-site monitoring,
