Q:What is the meaning of the camera uid?

Each uid corresponding to a user name on the general use of user name landing

Q:Monitor the camera what models

Longitudinal and under the "and too" series for the industry's top ten users recommend the brand. Product quality and cheap, trustworthy! Longitudinal and was with the major government, military, schools, enterprises and institutions are all cooperation.

Q:Monitor inside the infrared network camera infrared light automatically switch and synchronous switch What does this mean?

Synchronous switch has not heard, another set according to set the time to switch. For example, set 18 points to night into black and white

Q:Now the surveillance camera really tmd nonsense, four hundred or five hundred products with more than a hundred USB camera are not as good as poor resolution did not shadow, and generally are so, monitoring products are pit father,

Mode. CMOS is complementary to each other metal oxide semiconductor, CMOS is mainly the use of silicon and germanium made of these two elements of the semiconductor, through the CMOS on the negatively charged and positively charged transistor to achieve the basic functions

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 the camera automatically zoom, electric zoom, manual zoom, zoom lens meaning and difference?

Manual zoom: Change the focus on the front-end camera by manually rotating the lens. This function usually appears in the bolt + manual zoom lens configuration, set once, do not change later, if you want to change the focal length, need to open the shield again, rotate the lens. This type of lens usually needs to adjust the focus ring after the zoom work is completed.

Q:Monitoring camera POE power supply is good, or centralized power supply good?

With the POE-powered switch and the exchange of the difference between the exchange is enough to buy the power of the! POE power supply is a relatively high demand for the switch, the second is extremely unstable, but also increase the post-sale probability!

Q:What is the maximum visual range of a video surveillance camera?

Visual range with the camera lens: General: 4mm angle of exposure of 70 degrees, about 6 meters away

Q:Monitor how much power the camera has

General camera are 5W (with infrared) high-end are 10W ~ 50W ranging from the need to confirm the specific model (the manual will have).

Q:Use home computer camera how to install home monitoring?

The first transmission distance monitoring camera installation, generally need to use a few meters to tens of meters ranging from the transmission distance, but in accordance with the provisions of the USB standard, USB device, the longest transmission distance is 5 meters, so USB are Can not use long distance, which is what we use the USB camera to do monitoring the first problem encountered, the camera transmission distance. In fact, USB transmission distance can be resolved, USB can be extended through USB? HUB transmission distance, each additional HUB, you can extend the 5 meters, a total increase of 5 HUB, which is extended 5 times, each 5 meters, so The longest extension of 25 meters. Why is the USB demanding on the distance so strict? This is because the USB signal frequency is very high, the line in the process of transmitting the signal attenuation of the signal is very large, when the signal attenuation can not maintain the normal transmission of the signal, WINDOWS will prompt "to find unrecognized USB device" So the general distance can not be more than 5 meters!
