⚠️ Edgewood HOA RFI Notice & Community Advisory

UPDATE: 2024/10/12

The Edgewood HOA has powered back on all RFI-emitting equipment. They know this equipment is defective.

Need help filing an FCC complaint?

Please call Shane Hill @ (279) 252-8072 or email shanehill@edgewoodhoa.org.

The Edgewood Homeowners Association on Spyglass is causing many residents in the adjacent neighborhoods electrical problems, due to powerful radio frequency interference generated by their security camera system installed on and around the “Clubhouse” (poolhouse) and RV parking area.

The biggest issue for those living near the Edgewood property is the Radio Frequency Interference (RFI), which may affect Wi-Fi, television reception, bluetooth, cellular phone connectivity (including emergency calls), public-safety two-way radios, and sensitive medical devices (e.g., pacemakers, apnea monitors, powered wheelchairs). For example: source.

If you live adjacent to the Edgewood HOA—Kingswood Dr, Cypress Point, Doral Ct—you may also see aggressive weed growth from neglected landscaping, extremely bright parking lot lighting, and strange noises at night from parked RVs (all reported by neighbors).

If you look at the installation of the camera system:

It’s metal pipe conduit fastened to a chain-link fence and to the side of the clubhouse. The simplest, least-labor approach was used, contributing to the problems—despite the high price—and it’s also quite hideous.

The problem with the camera system is it emits powerful RFI—not even considering it’s expensive and inappropriate for our needs.

What is RFI? Radio frequency interference is electromagnetic interference (EMI) from unwanted RF signals that disrupt devices and radio systems. It can degrade Wi-Fi, TV/radio reception, cellular phones, and more.

I told Russ (Edgewood Board) our phones aren’t working reliably for texts and calls. “My wife and I discussed many times we’ve had problems making and receiving calls at home. We’re disturbed knowing that if we needed emergency services, we might not have been able to reach them.”

I offered tools, time, and even to purchase and donate replacement hardware if needed to resolve the issues. Nothing progressed until I threatened an FCC complaint. The RFI still persists to this day. More effort has been spent avoiding the issue than would likely ever have been needed to fix it.

The entire system has two identical endpoints: one covers the RV parking lot; the other covers the clubhouse/pool. They’re linked with dish antennas between fence and clubhouse. A short-range point-to-point microwave link here is dubious.

Both the PoE networking gear and power components generate RFI, which is propagated by the metal conduits and the chain-link fence acting like a giant antenna.

I believe most emissions emanate from the DC-DC buck converters powering switches/cameras with battery backup. RF travels through unshielded ethernet cables, couples to the conduit, and in RV Parking, the entire fence—creating high-voltage standing waves and very powerful RFI traveling a great distance, potentially impacting people hundreds of miles away in the evening, and within a few miles on the ground. The RFI can interfere with aeronautical communications even at 40,000 feet, line of sight.


UPDATE: 2024/10/15

Radio works with photons (like light) and can radiate in unusual patterns. A device might work near the clubhouse but fail on my second story. It may work today but not tomorrow.

The radiation pattern here is significantly vertical with lobes near ~40°, skimming my house. I couldn’t “see” the RFI near the ground.

This is a real, ongoing problem. When power is removed from the camera system, the RFI stops.

End update


Ubiquiti-brand PoE switches are notoriously noisy. The top spectrum image (from another report) shows Ubiquiti-related noise; the lower is our camera system—signatures are similar despite model/installation differences.

This system generates two distinct, powerful RFI signatures from both endpoints. For years I thought it was SMUD equipment and worked with a SMUD engineer—until isolating these emitters.

The power/redundant components and PoE switch (likely Ubiquiti) radiate at both endpoints. The long conductive runs act as antennas with poor RF grounding.

By reciprocity, if RF leaks out, RF gets in—these cameras have likely been unreliable.

Emissions are unlawful. Any time components are powered, they radiate harmful emissions.

This is an inadvertent transmitter, generating broad-band interference that moves around the spectrum. It can easily compromise law-enforcement and first-responder radio in nearby neighborhoods.

The frequencies also affect aeronautical and military HF, with a significant portion of RF energy directed upward.

I’ve spoken with affected neighbors on Kingswood Dr., Cypress Point Ln., and Doral Ct. Several are prepared to file FCC complaints.

The RV parking/tennis-court segment was powered down in March/April. I can’t get reliable information on the clubhouse system; RFI persists, though coverage shifted. (Per the Oct 12 update, the system has been powered back on.)


  • RFI can arise from devices that worked in the lab but fail in the field—public-safety dispatch can be degraded by receiver saturation and interference.
  • Under the right conditions, RFI can disrupt almost any electronic device—with potentially harmful results.
  • The FCC investigates unlawful RFI under the Communications Act and rules; complaints are routed to field offices.
  • FCC enforcement can include forfeitures, equipment seizure, injunctive relief, and criminal penalties.

Email suggesting trenching and undergrounding conduit
Initial contractor response suggests trenching/undergrounding—while denying cabling/cameras are a likely source.
Email restricting inspection and downplaying remediation
Subsequent email: little they’ll do; inexplicably bans my inspection of “repairs”.

Russ attempted to get support from Ubiquiti after failing to get traction with the installer. He forwarded a basic intake question from Ubiquiti Support; I asked to escalate since the offending components were already identified. I have never received any further communications from Russ.

Mitigations that may actually work:

  • Choke the cables: Clip-on ferrites (mix 31 or 43) on both ends of every Ethernet/PoE and DC lead; stack multiple turns if possible.
  • Shield & bond correctly: Replace long UTP with STP; bond shield to chassis/earth at one end (usually equipment end). Put PSUs and switches in metal enclosures with EMI gaskets; add an AC EMI line filter on the feed.
  • Don’t use the fence as a “ground”: Avoid attaching device grounds to the fence. If the fence is already bonded (often via posts), ensure it’s a clean earth bond and remove any accidental current paths from the equipment to the fence.
  • Cable routing: Keep low-voltage/data runs away from the fence and from long parallel metal (rails, gutters). Cross at right angles if you must.
  • Microwave radios: Keep dishes/horns physically clear of the fence (several feet), use proper radomes, and verify they’re on legal channels and within EIRP limits (side-lobes can illuminate nearby metal).

An initial email response Russ received from Mr. Security Camera of Sacramento is nonsensical. They claim the cameras and cabling are likely not the source of the interference, yet they go on to suggest trenching and undergrounding the conduit.

email from mister security camera of sacramento

A subsequent email from Mr. Security Camera of Sacramento to Russ.  They are telling Russ there isn’t much they will do.  Inexplicably I am banned from inspecting the repairs.  They know I will foil their attempts to not find or fix a problem.  To their credit, they are simply not capable of diagnosing and solving this complex electrical problem.

Email from mister security camera advising that Mr. hill can't inspect.

Russ attempted to get support from Ubiquity, likely after he failed to get any results from the camera installation company, Mr. Security Camera of Sacramento.  He forwarded this question from Ubiquity support to me.

I asked him if we could escalate the support ticket since I had already identified the system’s offending components.  I have never heard back from Russ.

Thanks for contacting Ubiquiti Support! I'm Stephen and I'll be assisting you with your request. It is difficult to diagnose the issue without knowing the specific details of your setup. If possible, could you share a diagram of your network setup along with the exact model of the antennas? However, you mentioned the interference is "excessive." Can you elaborate on the symptoms you're experiencing? This could be things like dropped connections on other wireless devices, slow speeds, or disrupted signals for other radio frequencies. Are there specific devices being affected by the interference? Knowing which devices are impacted can help narrow down the source and troubleshoot further.

Most of these emissions are generated when the RV parking system is connected to power.  Some are generated by the clubhouse system.
