Q:What is the meaning of the camera function heartbeat?
In the previous case, the implementation steps are as follows: 1, in a unified authentication system to open a "heartbeat" thread, the timing of the implementation of a visit A system operation, access to the A system S interface; 2, A system to achieve an interface S, Function for each access to an access request, then record a record of access, for example: 2009-3-18 fw 3, System A also need to also open a "heartbeat" thread, not separated by a certain time, access to the interface S is done Visit the record to see if the last record of the old record logo, if not, then prove that the single point of the system has the latest "heartbeat" came, its function is no fault.
Q:Camera clarity, 1080p. 3mp. 4k, what does it mean
1080P that is 1920 × 1080 resolution, progressive scan (equivalent to two million pixels)
Q:What kind of surveillance camera is good
According to your workshop size 8mm focal length, CCD1 / 3 inch camera almost, other parameters of course, the higher the better, but the price is higher, better international brand cameras have sony, Panasonic, Sharp, WATEC, etc. With the small, Shenzhen Weizi seems okay; I use the WATEC with 8mm, computar lens, the effect is good, the price of your side, a set of about 2800
Q:Monitor the camera, how much money one, the kind of video
20 meters of infrared one machine, domestic Sharp Rui tablets, between 180-300, SONY Rui film, between 200-400, which means that night vision can reach 20, if you are not demanding on the night, but the day See it, it is cheaper, Sharp Rui film 150, SONY Rui film 180. Give you a price, do not require the price of night vision.
Q:What is the difference between a dome camera, a gun camera and a dome camera in security monitoring?
Mainly the use of the difference, the dome camera is generally used for indoor ceiling place, because it is relatively small, so more beautiful. Gun camera is generally installed in the channel, plant or parking area and other areas. The advantage is that you can install long focal length lens to expand the scope of monitoring, the disadvantage is more obvious.
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:Elevator in the monitor camera lens focal length with the number
Elevator lens generally use wide-angle lens, commonly used wide-angle lens is 2.8 mm, 3.6 mm. Generally installed in the upper right corner of the elevator or the upper left corner of the location
Q:Monitor the camera live
Generally the case is the reason for static electricity, in theory, if your camera is using a transformer, that is DC power supply, then basically can be excluded from the leakage caused by the low-voltage (DC12V) camera, if There is a strong power into the words, then the camera will not be able to use, and here to note is not only the camera will have static electricity on your own may also have static electricity, you may say the same two cameras have a One is not, but you have to know the principle of electrostatic discharge, only when you come into contact with the conductive body when the static electricity can be released, you will have the feeling of Ma. In fact, if the camera is used properly, you do not have to worry about whether it is with static electricity, if you really worry, you can ground the camera, the general ceiling has a fire pipe and bridge, you can choose them to ground.
Q:What is the difference and connection between the optical zoom and the digital zoom of the camera in the security monitoring?
Optical zoom is that we often say that the mechanical zoom (manual and automatic), manual is the lens we usually zoom, auto zoom is common is that we use the ball machine and PTZ to pull closer to control zoom.
Q:Hello, because no electric video recorder did not manually set, but I would like to look back a few days before the monitor can be transferred out
1, if the surveillance camera is only access to the monitor, no access to the hard disk video recorder, video images are not stored, you can only see the real-time picture, can not playback.
