Jinsi ya kuchagua kebo za CCTV?

 

 

 

 

 

 

 

1. Video Cuwezo: SYV75-3 video cuwezo generally transmits within 200 meters, 75-5 transmits within 400 meters, and 75-7 can transmit 800 meters; the quality of CCTVCwaxialCuwezo ni muhimu pia,RG59U, RG6 Wote wawiliRG11 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 cuwezo transmission.

 

2. Kamba ya umeme: Flame-retardant cuwezos should be selected, and thicker ones should be used to reduce the attenuation of the power supply.

 

3. UdhibitiCuwezo:  Generally use shielded 2*1.0 cuwezo, RVVP2*1.0.

 

  1. Bomba la kukanyaga: Bomba la PVC au trunking ya PVC inaweza kutumika kwa ujumla, na bomba la mabati linapaswa kutumika kwa miradi ya chini ya ardhi au milipuko.
