Camera Frequently Asked Questions
 
Q: Why is our camera in the professional monitor image effect is very good, and in some no-name monitor, the TV image is poor and there is interference phenomenon?
  
A: Our camera output is standard 75 ohms, and some no-name monitors, TV input resistance is not standard. The solution is: in the monitor, the input of the TV and the ground side and a 75 ohm resistor.
   
Q: Why is our camera on the hard disk video recorder on the yellow side and not in the general monitor?
  
A: Because the camera in the factory standard on the image there are two settings: sharp or soft. The solution is to apply the soft standard to the camera in the hard disk video recorder.
   
Q: 3, the integration of the lens perspective than the general camera lens narrow perspective.
  
A: At present, the world's production of integrated lens (automatic zoom, zoom lens is the best of only two, they are the same lens perspective, so now all the integration of the lens of the lens are the same, and that there is no One of the integrated functions has improved in perspective.
   
Q: 4, the integration of the negative function of the machine what role?
  
A: The machine's negative function is mainly used in teaching, its role is to film (film) into normal mode displayed on the screen, (such as photo negative hair color is white, with the normal hair color is black opposite , The negative function of the integrated machine can restore the white on the film to black and display it on the big screen.
   
Q: 5, intelligent high-speed ball in the screen processor after the interference fringes.
  
A: Any weak product requires an external power supply using a standard power supply (the smaller the ripple factor, the better).
   
Q: 6, intelligent high-speed ball can add automatic tracking function?
  
A: This is the current security industry, a technical problem, there have been several manufacturers have been modified to try, but did not hear anyone who can succeed. At this time you can use the smart ball preset point, coupled with the alarm method to make up, such as: in the smart ball preset point, installed on the alarm, and compiled the corresponding procedures, once the alarm alarm, such as Fifth preset alarm alarm, the smart ball lens can be the first time to switch to the preset point to monitor, so you can greatly improve the monitoring effect.
   
Q: 7, backlight compensation in some circumstances the effect is not obvious enough.
  
A: As a manufacturer, we can according to the needs of customers for its corresponding backlash compensation function. Such as in a position only in the upper left corner of the screen to achieve backlight compensation function, in the lower right corner of the screen to achieve BLC function, we can achieve one by one.
   
Q: 8, the camera to increase the digital output interface (S terminal).
  
A: At present, the increase in the practicality of the interface is not, temporarily not increase.
   
Q: 9, black and white low solution, high solution is not obvious distinction.
  
A: You can distinguish between the following two aspects, a, on the intake of computer monitors have been activated, with less for the high solution; b, intake of some smaller characters, can clearly show the high solution.
   
Q: 10, the camera's resolution of the minimum illumination for how much?
  
A: Please refer to and remember the technical parameters of various cameras.
   
Q: 12, auto iris lens and camera match, often there will be some problems, I do not know why?
  
A: The auto iris lens servo motor drive in two ways, one is the DC drive, the other is VIDEO drive, their drive signal from the camera, so the camera's auto iris output signal also DC and VIDEO two, only When the camera output signal and the lens to receive the same way, the lens to work properly.
   
Q: 13, the monitor image clarity is not high, the details of the loss, serious color signal or color saturation will be too small, how is this going?
  
A: This is due to the high frequency of the image signal loss is too large to 3MHZ above the frequency of the basic loss caused by the signal. Such as the situation or because the transmission distance is too far, and the middle without amplification compensation device; or because the video transmission cable distribution capacitance is too large; or because the transmission link in the transmission line between the core and shield line appears a centralized distribution of the equivalent capacitance Caused.
   
Q: 14, why our products in the application process have to re-adjust the focus?
  
A: Because we are using the standard 8mm F = 1.2 lens test shipments, so as long as the use of F = 1.2 can be clear and do not have to move after the coke, with the lens angle has nothing to do (regardless of the lens a few millimeters).
   
Q: Why is the camera output image with thin strips of interference or coarse stripes rolling?
  
A: can be considered from the following two aspects: a, the power adapter quality (ripple is too large) caused by aging or bad, this time through a good camera to compare, with the same power adapter, if the phenomenon disappears The camera itself is caused by aging, it is recommended to return to repair, and vice versa to replace the power adapter. B, the machine appears coarse stripes rolling is generally the system wiring is subject to strong electric field interference, it is recommended that the machine to avoid strong installation, wiring, check the ground is solid, followed by the replacement of power.
