Balun FAQ:

1.     What is a BALUN? An acronym for BALanced/UNbalanced. A device commonly used to change one cabling media to another (example: coaxial cable to twisted pair Cat5 cable).

2.     Why use Video Baluns? Video Baluns provide an excellent solution to long cable runs for CCTV security surveillance cameras.  Typically video signals are limited to about 300' before video quality becomes undesirable. In situations where longer distances are needed video baluns are your best choice. Twisted pair and CAT5 cabling is much less expensive than the industry standard RG59 and Siamese cable making video baluns the best cabling solution for CCTV security surveillance cameras.

BNC Connectors FAQ:

3.     What is a "BNC" connector?  "BNC" connectors have a locking interface ring which is used when quick connect/disconnect connection are required. BNC connectors are used in CCTV security, laboratory instruments and radio equipment applications.

RG59 Cable FAQ:

4.     What does RG/U stand for?: Symbols used to represent coaxial cable that is built to U.S. government specifications (R=Radio Frequency, G=Government, U=Universal Specification)

5.     What is the difference between UL, CM, CMR or CMP cable ratings codes?  Cable rating codes mean that the cables meets different UL-NEC requirements based mostly on the quality of the cable jacket.

6.      Why does RG59 cable comes with different ratings, either 'CM', 'CMR' or 'CMP', as well as 'UL' ?  Below is an explanation of the rating codes for each cable type.  

7.     What is the correct choice of cable rating code for my job?   Below is an explanation of the rating codes for each cable type.  

8.     What is UL rated cable? - The National Electrical Code (NEC), published by the National Fire Protection Association (NFPA), details advisory safety considerations for electrical wiring. NEC Article 800 Communications Cables are manufactured to meet these different cable types.  Most network cables have some sort of basic UL rating.

9.     What is CM (R-732, R-752, R-757) rated cable?  - These are cables for general building wiring. CM cables are used in areas other than plenums and risers. These cables are resistant to the spread of fire and pass the UL 1581 Vertical Tray Flame Test.

10.  What is CMR (R-731, R-751, R-756)rated cable? - The 'R' in CRM is for 'Riser'.  Riser type cables are engineered to prevent the spread of fire from floor to floor and are suitable for vertical shaft applications

11.  What is CMP (R-733, R-753) rated cable?  - The 'P' in CMP is for Plenum. Cables meeting type CMP requirements are suitable for installation in ducts and plenums without the use of conduit. These cables are designed for fire resistance and low-smoke and toxin producing characteristics.  The 'P' in CMP is for Plenum. 

12.  Getting Full Category 5e Compliance
Using Category 5e cabling in your network installation does not necessarily achieve full Category 5e performance and 100BaseTX compliance. To achieve any category-rated performance, make sure all cabling components, including the modular plugs, trunk cables, and patch panels, are at least of the minimum category required.  To achieve full Category 5e performance and 100TX compliance, all components must be  Category 5e compliant and terminated properly according to EIA/TIA-568 TSB-36 and TSB-40 guidelines and tested with proper cable-certifying equipment.
