- Q: Monitor camera parameters how to see
- Aperture: the aperture installed in the back of the lens, the greater the aperture open, the greater the amount of light through the lens, the higher the clarity of the image; the smaller the aperture, the smaller the amount of light through the lens, the image clarity low. Usually with F (luminous flux) to represent. F = focal length (f) / light aperture. In the camera's technical indicators, we can often see 6mm / F1.4 such parameters, which indicates that the focal length of the lens is 6mm, luminous flux of 1.4, then we can easily calculate the aperture of 4.29mm. In the case of the same focal length f, F value is smaller, the greater the aperture, reach the CCD chip, the greater the luminous flux, the better the lens.
- Q: Monitor the camera when shooting white, is the kind of white, basically do not see the image, and exposure like
- The image is not adjusted, there may be two reasons, the first aperture is too large, the exposure is too high; the second brightness is too high, the best brightness, saturation, contrast recovery under the default.
- Q: What is the difference and connection between the optical zoom and the digital zoom of the camera in the security monitoring?
- Optical zoom is that we often say that the mechanical zoom (manual and automatic), manual is the lens we usually zoom, auto zoom is common is that we use the ball machine and PTZ to pull closer to control zoom.
- Q: What is the effective range of infrared surveillance cameras?
- Now that the effective range of infrared camera monitoring is how much, bad conclusion, the general infrared camera 3.6-6 mm camera is generally within 40 meters, belonging to the indoor machine and the door is dedicated to wide-angle lens.
- Q: Monitoring camera POE power supply is good, or centralized power supply good?
- If you have to use (see profits, you understand), it is recommended to choose some big brands of products, such as Huawei, 3com, etc., the cost is high, 20 meters if the use of oxygen-free copper feet .5 super five twisted pair , The loss on the wire can be ignored, but the use of POE power supply to consider the lightning ah, a break is a big string ah! :) POE to be used to do lightning protection measures Oh. And POE power supply in the event of failure when the investigation than the use of some trouble with the transformer.
- Q: 3.6mm and 6mm surveillance camera can see the screen angle is how much
- This depends on how much the face of the CCD friends, 1/3 is 71 degrees 1/4 is more than 51 degrees
- Q: Monitor the camera if the power supply to him a large current, pay attention to the current is not the voltage, the voltage is 12V, then what will happen to the camera?
- The current is very rare to see this situation, but the current is low, then I am sure that the monitoring head will appear like a pattern like interference
- Q: How to use the network cable to connect the surveillance camera?
- Short distance directly with the network cable can be, I remember as if 40 ~ 70 should be no problem (my longest used 20 to 30 meters). If you can buy twisted pair transmitter, then each pair of cameras need a pair of distance greater than 300 meters with active, active recommended front-end ground. If you use a network camera or a normal camera + digital module (this name is not allowed) direct crystal head + switch.
- Q: Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it
- 1/4 and 1/3 refer to the size of the camera's sensor chip. The camera image sensor (CCD or CMOS) has an area of 1/3 inch or 1/4 inch. The same manufacturing process and standards, the larger the image sensor (CCD or CMOS) area, the better the image quality (resolution).
- Q: Why mobile phone surveillance camera is always not online
- 2, with the network cable through the computer connected to the switch, you can see the online camera, and can also be connected through the Wifi wireless network IPAD, notebook, first of all to see if this camera is to support mobile phone viewing, if supported and this IP CAM has Access to the public network, and the phone is a smart phone that can be remotely monitored online
