Question six: daytime color reduction is not enough
Don't know what color you have noticed the infrared dome camera color will be more or less during the day, the most direct reason is the general problem of camera filters, Infrared Dome camera can through a certain proportion of Shuangfeng filter infrared light, the utility model has the advantages of low cost, but because the infrared ingredients contain more natural light. When will the interference color reduction after entering the CCD, such as green plants into gray and so on (the sun outside environment especially). The use of double IRCUT filter is an effective solution to this problem, IRCUT double filter by an infrared cut-off filter and a full spectrum of optical glass, when the light during the day when the full infrared cut filter, CCD to restore the true colors, when the night light is insufficient, the infrared cut-off filter automatically removed, the full spectrum of optical glass start to work, make full use of CCD to all light, thus greatly improving the performance of infrared.
Question seven: Infrared Dome camera without image
First check the external power supply output voltage polarity is correct, whether meet the requirements (power error: DC12V + 10%, AC24V + 5%), then check the video cable is good contact; if you use manual aperture lens to check whether to open the aperture, auto iris lens is required to adjust the aperture in the right position to LEVEL potentiometer. Richmor-China Professional Vechile video recorder manufacturer.
Question eight: infrared hemisphere camera image quality is not good
A. checks if the lens has fingerprints or is too dirty;
B. check that the aperture is properly adjusted;
C. check video cable for poor contact;
D. check the electronic shutter or white balance settings for any problems;
E. check if the transmission distance is too far;
F. check if the voltage is normal;
G. check for interference sources nearby;
H. check that the elevator should be insulated from the elevator during installation;
I. checks if the CS interface is connected.
Problem nine: infrared hemisphere camera images appear distorted or geometric distortion
This phenomenon may be a problem with the circuit or the optical lens problem of geometric correction of Infrared Dome Camera, monitor, there may be output impedance characteristic impedance video cable or device and Infrared Dome camera does not match. Richmor as a professional manufacturer, we focus on providing customers with the most advanced Hdd for dvr on sale.
When the above phenomenon occurs, please check the optical lens is abnormal and monitor input impedance, switch is set at 75 terminals, and then check the video connection cable impedance is 75.
