When to install PoE?
Consider the following scenarios:
• • You're planning to install the latest VoIP Phone system to minimize cabling
building costs when your company moves into new offices next month.
• • The company staff has been clamoring for a wireless access point in the picnic
area behind the building so they can work on their laptops through lunch, but the
cost of electrical power to the outside is not affordable.
• • Management asks for IP Surveillance Cameras and business access systems
throughout the facility, but they would rather avoid another electrician's payment.
