Q:Monitor camera parameters how to see

Focal length (f): focal length is the distance between the lens and the photosensitive element, by changing the focal length of the lens, you can change the lens magnification, change the size of the captured image. When the distance between the object and the lens is very far, we can use the following formula: lens magnification ≈ focus / material distance. Increase the lens focal length, enlarge the magnification, can be closer to the vision, the scope of the screen is small, the details of the vision to see more clearly; if the lens to reduce the focal length, magnification reduced, the scope of the screen expanded, See the bigger scene.

Q:Ccd monitor how the camera and computer connection

3. After the completion of the connection, the Internet to find a video software can start your video surveillance trip.

Q:How does the surveillance camera solve the backlight problem?

Second, always use the corresponding function of the camera, improve the backlit appearance. There are two kinds of cameras inside the security camera can be better to deal with the problem of camera backlight, one is a backlight compensation function of the camera, one is wide dynamic camera. Backlight compensation, also known as backlight compensation, is the screen dividends of several different areas, each area from the exposure. In some applications, the field of view can contain a very bright area, and the subject is included in the bright field surrounded by a picture of a bleak, no level. At this point because the AGC detects the signal level is not low, so the amplifier gain is very low, can not improve the brightness of the main screen, when the introduction of backlight compensation, the camera only the entire field of view of a sub-region, Area of the uniform signal level to determine the AGC circuit operating point.

Q:Infrared surveillance camera at night (no light) no picture and flash is how the matter

Is the daytime image normal? If the normal day, it is likely that the infrared light-related components are broken, there may be problems with the photoresistor.

Q:Home wireless surveillance camera price, how much money?

Q:HD camera is said that his clarity, infrared camera is that it's night vision function, in order to highlight the main features of the name of a

1, the camera generally talked about the camera, it is natural to think of home cameras. In fact, surveillance cameras and home cameras are many different, first of all fundamentally design standards are different, one for industrial applications and design, one for home use and design, so they work in a long time, the use of the environment The volume is small, the monitoring machine with small size, and the home machine because all the control parts and tape all installed in the same chassis, so the volume to be much larger, and must be on-site manual control, can not achieve remote remote control ; In the key resolution, the home machine is generally about 300 lines in the horizontal, and monitoring machine for the blackboard on the blackboard, the horizontal resolution should be more than 400 lines. The JY-803 integrated color camera, 480TV line center resolution, 1Lux low illumination, with automatic white balance, backlight compensation and automatic electronic shutter adjustment function, built-in 22x optical lens.

Q:Monitor the camera often flashing why
