In the world of surveillance, Power over Ethernet (PoE) plays a crucial role in ensuring a seamless and efficient power and data connection for security cameras. As a leader in innovative camera housing solutions, we utilize Pass-Through PoE in our housings to accommodate various installation needs. In this blog, we will explore the key differences between Passive PoE and Pass-Through PoE in Dotworkz camera housings and how they impact your surveillance setup.

What is Power over Ethernet (PoE)?

PoE technology allows network cables to carry electrical power along with data, eliminating the need for separate power sources for devices like IP cameras. This simplifies installation, reduces costs, and improves reliability in surveillance systems.

Passive PoE in Camera Housings

Passive PoE is a straightforward method of delivering power to network devices without adhering to the IEEE 802.3af/at PoE standard. Instead of negotiating power levels dynamically, Passive PoE simply delivers a fixed voltage to the connected device.

Key Features of Passive PoE:

• Fixed Power Output: The power is always supplied at a constant voltage, typically determined by the power source.
• Non-Standard Implementation: Unlike active PoE, Passive PoE does not have built-in negotiation, making it necessary to ensure compatibility with the camera.
• Simplified Design: Passive PoE systems often involve simpler wiring and cost-effective solutions for installations where power requirements are known.
• Limited Protection: Since there is no power negotiation, incorrect voltage supply can damage non-compatible devices.

While some camera housings in the market utilize Passive PoE, it is important to verify compatibility before implementation.

Pass-Through PoE in Dotworkz Camera Housings

Dotworkz employs Pass-Through PoE in its camera housings to ensure reliable and standardized power delivery for surveillance systems. Pass-Through PoE is designed to pass the PoE signal through the camera housing without altering its power characteristics. This means that whatever power the PoE switch or injector provides is delivered directly to the camera inside the housing.

Key Features of Pass-Through PoE:

• Maintains IEEE PoE Standards: The camera receives power based on the IEEE 802.3af/at/bt PoE standards, ensuring compatibility and safe operation.
• Flexible Power Distribution: Can support high-powered devices without the need for additional power converters.
• Ideal for Complex Installations: Pass-Through PoE is perfect for installations where multiple devices, such as cameras and other peripherals (e.g., heating and cooling systems), need power without modification.
• Enhanced Safety: Since power is negotiated between the switch and the camera, there is less risk of voltage mismatches.

Why Dotworkz Uses Pass-Through PoE

Dotworkz integrates Pass-Through PoE in its camera housings to provide a robust and flexible power solution. By adhering to IEEE standards, Pass-Through PoE ensures seamless integration with a wide range of security cameras, reducing installation challenges and improving overall system reliability.
