Q:Monitor the camera often flashing why
Video head problems, poor contact performance. The video head to try again.
Q:What do I need to do with video surveillance systems?
Video surveillance system developed a short period of twenty years, from the 19's 80's analog monitoring to hot digital monitoring and then to the Internet video surveillance, has undergone enormous changes. In the IP technology gradually unified global Today, we need to re-understand the history of video surveillance system development. From the technical point of view, the development of video surveillance system is divided into the first generation of analog video surveillance system (CCTV), to the second generation based on "PC + multimedia card" digital video surveillance system (DVR), to the third generation based on IP network video surveillance System (IPVS).
Q:What is the difference between monitoring cameras CCD1 / 3 and 1/4?
Only 1/3 inch, 2/3 of the lens through the aperture of 2/3 inch, so under the same lighting conditions, 2/3 lens allows more light through, thus indirectly enhance the camera's illumination, ? 16MM of the small perspective, according to far, 8MM lens perspective, according to the relative, relatively speaking, the principle of record: the greater the number, according to the more distant, the smaller the angle; the smaller the number, The more widely
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.
Q:What is the power consumption of the camera day?
This power consumption is negligible. The The 10 cameras plus 24 hours can consume about once electricity
Q:Will the video surveillance camera screen will jump out of this camera settings like the option?
If you can not quit, you can power off the camera after a few minutes to re-power, there is no, if the process is often used for no reason to jump out of the menu, you have to consider whether the control keyboard is faulty, or control the line whether there is interference , Causing garbled.
Q:Can the general camera be monitored?
Schools, hotels, public places Camera: with a single hard disk can be a single branch, you can also run the network, you can also real-time monitoring. Features: high rate requirements, large data capacity, long storage time.
Q:Hai Kangwei depending on the surveillance camera how to achieve continuous automatic capture, such as a second catch a?
If you want to install ten cameras then the traditional camera is necessary for each coaxial line must be inserted at the same time a video recorder can be used normally, but the network camera can add a switch, that has ten network switches into only need Through a network cable to pull another switch on the normal use, so do not have to spend a lot of trouble, save a lot of labor)
Q:An accurate calculation formula for monitoring the focal length and actual distance of the lens
While the use of long focal length lens can see the car's license number (the car occupies most of the area on the screen), but can not monitor the entire car park
Q:Monitor the camera why the black screen?
First, check the power supply under the surveillance camera is a problem, if it is infrared surveillance cameras, can see the red light at night, then that power supply normal; if not, you can use a multimeter on the power supply and power lines to measure.
