RF Interference on Amateur Radio HF Frequencies

Subject: RF Interference on Amateur Radio HF Frequencies
Model # RLK16-810B8-A
(REOLINK H.265 4K PoE Security Camera System, 8pcs Smart 8MP Wired PoE IP Cameras with Person Vehicle Detection, 8MP 16CH NVR with 3TB HDD )

System cause extreme radio interference to Amateur Radio HF (High Frequency) spectrum.

Specifically interferes from roughly 1- 30MHz. I hear extreme "hash'" and other spurious emissions RF noise on many frequencies including and not limited to 14.212Mhz, 18.181Mhz, 21.173Mhz, 24.959Mhz and 28.500Mhz.
I am sure it is coming from your switching power supply, but may also be from the NVR too.
It may also be radiating along the Cat5 cables.

This essentially makes a good portion of my amateur radio frequencies useless!

I would like to know whar Reolink has to say about this problem.

@karate8_435410537787569 After nearly a week of removing all of my network and replacing everything, after unplugging my Reolink NVR...my noise vanished on my station. My issue is with specific 2 meter repeaters. It causes a big enough bubble that goes away after I leave my driveway.

@karate8_435410537787569 I also have this issue. I'm thinking a majority of the noise is coming from the NVR itself rather than the power supply, because it only starts happening once the POE starts up for the cameras. Did you ever find a solution to this?

Proper grounding ensures that RF noise is conducted away to the ground instead of being emitted as radiation. Shielding, filtering, and grounding are the immediate answers to the question of how to stop radio frequency interference in electronic circuits.

Same issue here. The noise begins once the cameras link up with the NVR and the noise changes once the video stream starts. The interference is ridiculous. Any solutions to this yet?

great information that I can find on the radio en ligne. They are more interesting and unique than ever

Radio Frequency (RF) interference on amateur radio High Frequency (HF) frequencies can be a frustrating issue for radio amateurs. Interference can come from a variety of sources, including nearby electrical devices, poorly designed or malfunctioning electronics, and even natural phenomena like lightning strikes or solar flares.
Here are some steps you can take to help mitigate RF interference:

1. Identify the source of the interference: To start, you will need to identify the source of the interference. This can be done by disconnecting all of your equipment and antennas from the power source and then systematically adding them back in one at a time until you can identify the source of the interference. This process is known as "isolation."
2. Ground your equipment: Grounding your equipment can help to reduce the effects of RF interference. Ensure that all of your equipment is properly grounded, and that the ground connections are secure and not corroded.
3. Use a choke: A choke is an inductor that blocks high-frequency signals from passing through. You can add a choke to your coaxial cable to help reduce RF interference.
4. Use a filter: Filters can be used to remove unwanted signals from the radio frequency spectrum. You can use a filter to block out frequencies that are causing interference.
5. Use shielded cables: Shielded cables are designed to block RF interference. You can use shielded cables to connect your equipment and antennas.
6. Position your antenna: Sometimes, the position of your antenna can affect the amount of interference you receive. Try moving your antenna to a different location, or using a different type of antenna.
7. Consult with other radio amateurs: If you are unable to resolve the interference issue on your own, consider consulting with other radio amateurs. They may have experienced similar issues and may be able to provide additional advice and support.

It is important to note that while RF interference can be frustrating, it is also a part of the hobby of amateur radio. By following the steps above and working to mitigate interference, you can continue to enjoy your hobby and communicate with other radio amateurs around the world.
