Modern day Time Clock Systems now use a single cable to provide both data connection and electrical power to Biometric, badge, clock card systems and even keypad entry time clock terminals.
Aptly named Power over Ethernet or PoE, uses standard IEEE 802.3 technology in which CAT 5 and higher data cables have 4 pairs of internal wires and where only two of are needed for data transmission, power is transmitted unused wires. Hence the name, Power over Ethernet, or PoE for short, that’s PoE, not Poe, as in Edgar Allen.
Because PoE provides both data and power connections from a single cable the
need is immediately reduced as far the number of data cables needed for time
clock terminals and timeclock data collection devices. But there are considerable more benefits to
the use of PoE. Since fewer cables are
required, installation is expeditious and uncomplicated. CAT5 class cables are lower in price than
other power cable alternatives, and low voltage making permits and code unnecessary
on most jurisdictions and less complicated than standard electrical code in
others. Administrators can remotely power cycle devices and equipment, which is
important for multi site facilities. And
unlike USB standards which also power devices over data cables, PoE allows for
much longer cable lengths. This makes PoE a good option for not only for automatic
time clocks, but any device requiring long cable runs, such as wireless access points, IP Phones,
and IP Cameras.
Many of the time clock devices offered from TimeClockMan.com offer standard
PoE technology
include the many obvious advantages in comparison to other data
cable alternatives.
