What are the problems with the surveillance camera?
Wait for you to meet the situation to say it again, I give you answer, you ask the question is like to buy a mobile phone, mobile phone will generally what the same problem. People are so depressed! The The Surveillance cameras, Dongguan Le Pu Electronic Technology Co., Ltd., this is very good!
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.
What is the number of lines that a surveillance camera needs to use?
3, the control line (it is the PTZ, the spherical camera control line, with a two-core dvvr line)
Monitor how the camera is connected
2. How to use the cable connection to monitor the camera cheap. The price of the ordinary ultra-five cable is quite comparable with the 75-3 video cable, the outdoor waterproof super five cable prices are comparable with the 75-5 video. VGA cable (also known as VGA cable, signal line, image transmission line), is used to connect the host computer and monitor. The general minimum length of the standard shall not be less than 1.5M, without both ends of the thread. The market also has 1.8M, 2M, 2.5M, 3M, with a host computer, these lengths are generally used for foreign customers. The maximum length of the VGA is not a uniform standard, how long do you want to do to give you how long to do, of course, the line is too long, the impact of image transmission. Moreover, the price is very expensive, the maximum length can do 30M has been very good.
What is the minimum illuminance indicator of the surveillance camera?
IRE Level: The maximum amplitude of the video output of the CCD camera is generally set at 100IRE (or 700 mV), and a 100IRE video indicates that you can fully drive a monitor to show the best brightness and contrast image quality. 50IRE video shows only half the contrast, 30IRE (or 210 millivolts) that only 30% of the original amplitude, usually 30IRE is the lowest performance available image value. So there is no indication of the lowest illuminance results of the IRE grade and are not actually comparable. Finally, it is the camera's special function settings.
What kind of monitoring camera is used in the store? 360 ° with the introduction of ordinary
If you consider the general monitoring, select the analog camera, ordinary video recorder (remember with a hard disk), plus a display, the estimated cost of 1000-1500 or so.

It should be accidentally transferred out of the camera settings menu, if it is, then select the corresponding camera, and then exit the menu
Monitor the camera gray screen
1, power reasons. The basic can rule out this reason, because it has been running for 2 months. If you do not worry about the power, you can do this: remove the camera, change the new power (or now use a normal) next to the host test. (Because the output line of the power cord is too long, there may be insufficient voltage.)
