Connecting two PoE switches to a Network Video Recorder (NVR) can sound intricate, but with the right guidance, this configuration can be achieved effortlessly.
This article delves into everything you need to know about how to connect two PoE switches to an NVR, ensuring optimal performance for your surveillance system.
Understanding PoE Technology
Before diving into the steps for connecting two PoE switches to your NVR, it’s essential to understand the fundamentals of PoE technology.
What is PoE?
Power over Ethernet (PoE) is a technology that allows network cables to carry electrical power alongside data. This setup eliminates the need for additional power cords for devices like IP cameras, VoIP phones, and wireless access points. By integrating power and data transmission, PoE simplifies installation and reduces equipment clutter.
Types of PoE
There are several types of PoE standards available today:
- IEEE 802.3af: Provides up to 15.4 watts of power per port, suitable for most low-power devices.
- IEEE 802.3at (PoE+): Offers up to 30 watts of power per port, catering to higher-power devices such as PTZ cameras.
- IEEE 802.3bt (PoE++): Delivers up to 60 watts per port, ideal for devices that require more power, like certain advanced IP cameras and network switches.
Understanding these standards is crucial when selecting your PoE switches to ensure they meet the power requirements of your NVR and connected devices.

What is a PoE switch and how does it work?
A Power over Ethernet (PoE) switch allows network cables to carry electrical power along with data. This eliminates the need for separate power sources for devices such as IP cameras, VoIP phones, and wireless access points, streamlining installation processes. Each port on a PoE switch can deliver power to connected devices while also facilitating data communication over a single Ethernet cable.
By using PoE switches, you can simplify your networking setup, reducing both cable clutter and installation costs. They are particularly beneficial in scenarios where it’s challenging to install electrical outlets, such as outdoor environments or ceiling-mounted devices. The switch identifies the PoE requirements of connected devices and supplies appropriate power levels as needed.
How do I connect two PoE switches together?
To connect two PoE switches, you’ll need an Ethernet cable that complies with the appropriate category (Cat5e, Cat6, or higher) specifications for your network’s requirements. Connect one end of the Ethernet cable to a PoE port on the first switch and the other end to a PoE port on the second switch. Ensure that both switches are powered on during this process.
Once connected, the switches will communicate with each other, allowing devices connected to either switch to share data seamlessly. Make sure to monitor the PoE power budget for both switches to ensure that the ultimate power delivery to connected devices remains within limits. This connection will enhance your network’s performance and reliability.
What is an NVR, and why is it important in a PoE setup?
A Network Video Recorder (NVR) is a device used for recording video footage from IP cameras over a network. In a PoE (Power over Ethernet) setup, NVRs play a crucial role by receiving video data directly from PoE-powered cameras. This integration eliminates the need for additional power sources, as the cameras can be powered and networked simultaneously through a single cable.
Using an NVR allows for centralized management of video feeds, providing better control over recording schedules, storage management, and live viewing options. It also enhances security by enabling remote access and monitoring capabilities, thereby offering peace of mind and efficient surveillance solutions.
Can I connect non-PoE devices to a PoE switch?
Yes, you can connect non-PoE devices to a PoE switch; however, the non-PoE devices will not receive power from the switch. The Ethernet port on the switch will provide data connectivity but will simply ignore the power aspect for those devices. When connecting, ensure that your non-PoE devices are Ethernet-compatible to maintain data communication.
It’s beneficial to use a PoE switch even if some ports are going to non-PoE devices. The flexibility allows for future upgrades where more devices may be added, allowing for improved scalability within your network configuration.
How do I troubleshoot connectivity issues between two PoE switches?
If you’re experiencing connectivity issues between two PoE switches, start by checking the physical connections. Ensure that the Ethernet cable is securely plugged into both switches, and check for any visible damage to the cable. Additionally, verify that both switches are powered on and functioning correctly; indicators on the switches can help you assess their status.
If the connection remains unresponsive, perform network tests to isolate the issue. This may include pinging devices connected to each switch or using network diagnostic tools to analyze traffic. Reviewing the PoE budget can also be pertinent, as exceeding limits may lead to insufficient power delivery, affecting overall functionality.
Do I need to configure settings for connecting PoE switches to the NVR?
While basic configurations may not be necessary for connecting PoE switches to an NVR, it is essential to ensure that each device is correctly set up for optimal performance. Typically, if both the NVR and PoE switches support Auto-Negotiation, they can self-configure the most suitable settings for data transfer and power delivery. However, manually setting IP addresses may be required depending on your network architecture.
Before finalizing your setup, check the NVR settings to confirm that it recognizes the connected cameras and that the right IP addresses are assigned. Ensuring that the firmware for both the NVR and the PoE switches are up-to-date can also play a key role in avoiding compatibility issues and leveraging new features for a smooth operation.
