Q:Wireless surveillance camera security is not? Easy to be peeped not? LAN and external network access speed how?: That visit is the time of video transmission, of course, will be faster in the local area network if you want to visit soon need to have a high bandwidth of LAN connection.

Q:What is the difference between a dome camera, a gun camera and a dome camera in security monitoring?: Hemisphere is generally installed ceiling, the bolt is installed on the wall, whether with infrared light, the size of the lens according to the actual situation and customer requirements to consider. The dome can be rotated 360 degrees, set the preset position can be automatically cruise, you can automatically zoom to the center of the scene picture auto focus, keep the image clear, you can also manually focus.

Q:Wireless micro-surveillance camera how to see what to shoot: If it is with memory, then the memory card can be placed on the card reader to the computer to play, if there is no memory, then there is a receiver, the receiver connected to the hard drive will receive the signal stored in the hard drive, Can be played through the hard drive on the monitor.

Q:Monitor camera parameters how to see the bigger the bigger the better?: The more the focal length, the more able to shoot distant objects, but the smaller the perspective, so depends on your specific needs, if you need a large range, you have to choose a small focal length, if you need to shoot distant, then select Focal length.

Q:What is the effective range of infrared surveillance cameras?: 6 mm more than a narrow angle lens, the general effective distance is about 100 meters. And some 25 mm is about 150 meters, if the high-speed laser PTZ machine can reach 300 meters of infrared distance, but this cost is very high, about 13,000 or so, commonly used lens general angle is as follows: 2.8mm 101 ° 3.6 Mm 83 ° 4mm 76 ° 6mm 53 ° 8mm 35 ° 12mm 28 ° 16mm 21 ° 25mm 13 ° 1 / 3CCD and 1/4 CCD angle difference around 20 ° Hope to help you.

Q:Remote monitoring principle: Network communication using TCP / IP and network multicast (Multicast) technology, to maximize the use of the network transmission performance and network bandwidth, to avoid network congestion.

Q:Monitor the camera's focal length how to choose?: First, choose to monitor the camera lens also pay attention to the focal length of the lens, the focal length is actually the perspective of the problem, the focal length of different perspectives are also different.

Q:How quickly remember to monitor the camera model, to do business, such as the DS_2CD3T20D-I5 which is what is the Thank you: 1.3 "structure type code is represented by a capitalized English letter, where:" C "means analog camera," H "means dome," Z "means one machine," M "means one machine movement," D " The

Q:Monitor what is good for video recorders: Dahua's software is easy to use, but DVR's BNC plug is easy to loose, resulting in poor contact, sometimes the channel screen will not show or interfere with the screen.

Q:The working principle of the camera with infrared light: Second, the infrared camera imaging principle In the night vision monitoring system, the conventional approach is to use the visible light, but this way there can not be hidden, easy to monitor the target and other shortcomings, so use less; the current hidden, scientific night vision monitoring Is the use of infrared camera technology. Infrared camera technology is divided into passive and active. Passive infrared camera technology is the use of any substance in the absolute zero (-273 ℃) are more than infrared radiation, the higher the temperature of the object, the more infrared radiation. The most typical of the cameras made with this principle is the infrared camera, but this special infrared camera is expensive and therefore limited to military or special occasions. The active infrared camera technology is the use of infrared light radiation "lighting" (mainly infrared light), the application of ordinary low-light black and white camera, color to black and white camera or infrared low-light color camera, feel around the scene and the environment reflected back to the infrared light to achieve Night vision monitoring. Active infrared camera technology is mature, stable, become the mainstream of night vision monitoring.
