Q:Outdoor surveillance camera what brand good ah

According to the camera brand, then the following brands are very good.

Q:Outdoor surveillance camera that kind of good, how the price

In the TV monitoring system engineering design, often involves the TV monitoring system equipment selection, especially the front-end camera part and the terminal display part of the match is very important. Therefore, we use the TV monitoring system equipment, can not be any match, according to the monitoring of the environment of the environment and the conditions of illumination and the requirements of the target to be monitored, follow a certain principle to choose.

Q:What is the number of lines that a surveillance camera needs to use?

1, the power cord (12v power supply and 220V power supply, dvvr2 * x, is to the camera power supply)

Q:An accurate calculation formula for monitoring the focal length and actual distance of the lens

The size of the imaging scene and the size of the imaging object are contradictory, for example, with the same camera to monitor the same parking lot, the choice of short focal length lens can be the entire parking lot to monitor and see the entrance Outside the vehicle out, but can not see the car's license number (the car in the monitor screen only occupies a small area)

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

Automatic switch, that is, the camera detects the outside environment, light black to a certain degree of image to turn black and white. Morning to a certain extent turn color.

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:Is there a surveillance camera that can be plugged in

Oh, the first kind of camera is generally by the lens, image sensor, analog / digital converter, image control And other parts of the composition, if the audio function, then, coupled with the sound collection, processing and transmission components.

Q:Ready to engage in a facade ... to help people engage in monitoring. General how much of this type of profit. How to charge.

Camera technology in this country has been very mature! Profit margins and before is immeasurably! Now you can do this i do! Products are almost! Business only to reduce the price to win the market! Now a lot of camera manufacturers struggling, there is no sales they simply can not live! The price is also very transparent! Chips are the same, why are you expensive for me? Of course, except for the relationship! So now this line is not very good to do! If there is a relationship, get a brand! This piece can still be considered!

Q:Can I monitor the camera directly on TV?

Can be directly connected to the TV, but can not video, the camera that you see the range, to the market and they say that this can be the case, they will give you with a good

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 voltage is constant, the current is not increased, such as the camera comes standard with the adapter power supply is 12V / 1A, if the switch for 12V / 5A or 10A, 20A power supply is the same, will not have any impact on the camera. The actual operating current of the camera does not increase as the power of the power increases.
