Passive POE (Power-Over-Ethernet) Injector for IP-Camera / VoIP / WiFi Access Point 12v|48v

A passive Power over Ethernet (PoE) injector is a device used to deliver power to network devices, such as IP cameras, VoIP phones, and wireless access points, through an Ethernet cable. This eliminates the need for a separate power supply, simplifying installation and reducing cable clutter.

Power Delivery:

* Voltage Range: Supports a wide input voltage range, typically from 12V to 48V, making it compatible with a variety of network devices.
* Passive PoE: Unlike active PoE, which negotiates the voltage with the powered device, passive PoE delivers a constant voltage. The devices connected must be compatible with the voltage provided by the injector.

Components:

* Injector: The main unit that combines the Ethernet data and power into a single Ethernet cable.
* Ethernet Ports: Usually has two Ethernet ports: one for the data input (from the network switch or router) and one for the combined data and power output (to the powered device).
* Power Input: A power jack for connecting to an external power supply that provides the necessary voltage.

Applications:
        
IP Cameras: Used to power surveillance cameras that are installed in areas where it's difficult to run separate power cables.
VoIP Phones: Provides power to VoIP phones, simplifying installation on desks and reducing cable management issues.
Wireless Access Points (APs): Supplies power to APs, enabling flexible placement in optimal locations for signal coverage without needing a nearby power outlet.
Other Network Devices: Suitable for various other PoE-enabled network devices.

Benefits:
        
* Simplified Installation: Reduces the need for separate power lines, making it easier to install devices in locations without easy access to power outlets.
* Cost-Effective: Generally less expensive than active PoE solutions and PoE switches.
* Flexibility: Allows placement of devices in optimal locations for performance without being constrained by the location of power outlets.

Considerations:
        
* Device Compatibility: Ensure the connected devices are compatible with the voltage provided by the passive PoE injector. Connecting a device that requires a different voltage could damage it.
* Distance Limitations: Passive PoE may have limitations in terms of the maximum distance over which it can effectively deliver power, typically up to 100 meters (328 feet) over Ethernet cabling.
* No Negotiation: Unlike active PoE, which can negotiate power requirements, passive PoE provides a fixed voltage, so devices must be manually checked for compatibility.

Example Use Case

Imagine you are setting up a security system with IP cameras around your property. Instead of running separate power cables to each camera, you can use passive PoE injectors. Each injector will combine power and data onto a single Ethernet cable, making it easier to install the cameras in optimal positions without worrying about nearby power outlets.
