Summary
This article outlines the Power over Ethernet (PoE) standard and the power requirements for various products. It is relevant for all Hanwha PoE-enabled devices.
PoE Types
The different types of PoE:
- Type 1 - Most standard cameras using less than 15.4 Watts of PoE power
- Type 2 - Include outdoor housings such as the SHB-4300HP, PTZ cameras without IR, and some multi-sensor cameras
NOTE: Always check the specification sheet before starting
the installation and hook up. - Type 3 and Type 4 - Used in products such as the PNM-9084/9085RQZ/QZ, PNM-9322VQP, etc.
NOTE: Always check the specification page of the product you
are installing.
Wattage Requirements
Devices falling into the Type 3 or 4 power consumption range can experience constant reboots if they are not connected to a properly rated injector or switch.
NOTE: Hanwha currently stocks (and ships with our devices) 60-watt
and 83-watt injectors that are compatible with our devices requiring
these outputs. For current part numbers and pricing, please contact
insidesales@hanwha.com.
NOTE: Refer to Hanwha's Networking and Transmission Accessories to
compare products.
To ensure proper functionality, connect the camera separately using the correct wattage output injector for the device. If using a PoE switch more PoE capabilities than needed, verify the LLDP settings are correctly configured.
PoE standards allocate power at the switch, and then deliver it to the camera.
- For standard PoE - The camera can consume up to 12.95W, while the switch needs to allocate and consume up to 15.4W.
- For PoE+ - The camera can consume up to 25.5W and the switch needs up to 30W. IMPORTANT: Depending on its specifications, this can lead to a PoE budget shortfall if the switch is fully loaded. Always make sure the switch has enough power to meet the demand.
NOTE: Most switches use LLDP to determine if a device, such as a
camera, requires more than 12.95W of power. However, many managed
switches may appear to have PoE+ with LLDP enabled but often
require additional configuration in the command line.
