Here is the factsheet . . .
PoE switch ( Power over Ethernet switch ) was invented around 1999.
PoE switch was designed to run various remote IP devices by providing them both power and IP data link, so that they can operate without need of external power.
Later in 2003 , IEEE laid down the specifications for the PoE switch ~ IEEE 802.3af
Thereafter , it's wide usage started for running many different devices.
It was designed as a generic product to run several type of IP devices which need very low to a certain level of power.
Example of devices it can run :
IP cameras , IP phones , IP sensors , IP controlled relays , IP Access Points , IP Speakers and many other standalone devices.
In reference to IP CCTV cameras , following are the 'Facts' and 'Problems' of PoE switches :
In a standard PoE switch . . .
Facts :
( But practically it can run max upto 60-70 mtr only )
Problems :
Moreover , PoE switches cause these problems in IP cameras :
Still , for last more than 20 years , PoE switches are being used to run IP cameras worldwide.
Thereafter , our technical head , who is qualified from IIT Roorkee ( B.E. E&C - 1984 , M.E. E&C - 1986 ) invented an alternative and very revolutionary solution in 2023 to run IP cameras . .
'CLD PoE Tree in Air'
PoE switch was invented for generic use and later IP Cameras were also run by them.
While after analyzing IP Cameras , ‘CLD PoE Tree in Air’ was invented specially for them.
Govt. of India has already granted Patent for this innovative and game changing technology for IP CCTV installations !
While , the Patent application is pending in USA & CHINA.
It results full 100% performance from all cameras which customers need for their security.
And upto 50% or more savings in Copper Cat6 cable , Manpower and Time. And Super Reiliability for years to come.
