Ungazikhetha kanjani izintambo ze-CCTV?

 

 

 

 

 

 

 

1. Ividiyo Cuyakwazi: SYV75-3 video cuyakwazi generally transmits within 200 meters, 75-5 transmits within 400 meters, and 75-7 can transmit 800 meters; the quality of I-CCTVCoxialCuyakwazi kubalulekile,RG59U, RG6 KokubiliRG11 and RG11 require 100% copper core and 95% copper braided shielding layer. The maximum resistance of the circuit loop connection cannot exceed 15 ohms. When the distance exceeds 500 meters, it is necessary to consider the use of optical cuyakwazi transmission.

 

2. Intambo yamandla: Flame-retardant cuyakwazis should be selected, and thicker ones should be used to reduce the attenuation of the power supply.

 

3. UkulawulaCuyakwazi:  Generally use shielded 2*1.0 cuyakwazi, RVVP2*1.0.

 

  1. Ukuchusha ipayipi: Ipayipi le-PVC noma i-PVC trunking ingasetshenziswa ngokujwayelekile, futhi ipayipi lensimbi lashukumisa kufanele lisetshenziselwe amaphrojekthi angaphansi komhlaba noma wokuqhuma.
