RF Detector?

If you have specific devices, it will be easier to help.
I doubt a neighbor will block that big of a spectrum.

Ok, he seems to be targeting the NVR and cameras. Doesn't seem like anything else has issues. I'm not sure what spectrum would cause issues with the camera system. Sometimes, I turn on the monitor, and the NVR is on a single camera instead of the camera overview screen, other times it is on the playback screen, which requires a password to access.

Here's another thing, he used to play vehicle shuffle on a regular basis. Meaning he moved several vehicles to different positions on his front lawn. Wonder if they may have something to do with finding the best location for RF. Then the vehicles were put in his back yard and the "coil" of wire appeared leaning against the bottom of his fence perpendicular to our house.

Again, this could be an issue with the NVR, but I would like to have peace of mind knowing if there might be RF being emitted.

Do you have any wireless component in your NVR/Cameras setup?
If not, I don't see way he could affect you (unless he is very close to the Ethernet cable), the more probable option is someone hacked your NVR or a a configuration issue.

No wireless components in the NVR/camera system. And the NVR and cameras are not connected to the network or internet. It is a standalone system.

I really believe it is directed RF energy causing the random issues. I say this because my movie film capture machine started dropping frames as of this morning. Something is interrupting the data transfer, slowing or corrupting the data rate causing the dropped frames and it is very random. It will be fine, then drop 4 or 5 frames in a row and then be ok for a period and then drop 4 more. I don't use this machine daily, only when I need to capture film which could be 3 days straight or it may sit for a month or 2 before being used.

I'm going to start with the 3 in 1 EMF, ELF and RF analyzer

This can be a new anti drone weapon if someone got it working.
I doubt your neighbor have these tools, but please update us with your findings.

The old saying, "never underestimate your enemy", holds true here. I have no idea what he is capable of. I have to presume the worst and hope for the best. A little investigative work goes a long way to collecting actual evidence.

I'll update when I have made some scans.

Waiting for the RF analyzer. In the meantime, whatever is causing the odd behavior, it's definitely local since the NVR is not connected to the net. A one in a million chance it is a failing NVR, but I doubt it as I don't think a failing NVR would either choose camera one from the available cameras, or show the main record screen, which again needs a password to access. Someone local is accessing the NVR wirelessly somehow.

And while I was out cutting the grass this morning, when I came in, the monitor was on camera 1 and not the camera overview screen like it is always on. I personally think he seen me out front and decided to pull his little prank.

I never did a damn thing to this guy and he's hell bent on trying to make my life miserable.

Got the scanner today. Walked around our entire property and the RF readings are higher in his direction than any other.

Viewing the RF table, the RF most prevalent frequencies are 430Mhz and 2.4 Ghz. Now I know 2.4 is Wi-Fi frequency, but the signal from his direction was peaking at 4 to 5 watts.

Oddly enough, shortly after walking around outside with the scanner and going inside, he opened his garage door did something in the garage and near the fence then closed the door.

Now when I view the RF table, I see 430 MHz at low power and random infrequent spikes of 2.4 GHz at no more than a half watt in strength

I'm going to continue to monitor the airwaves to see if we can see a pattern. It's nice that this scanner has a data logger and date and time to pinpoint spikes

The 2.4 GHz emissions from his direction had readings of 4 - 5 watts of regular cyclical spikes, prior to his "adjustment" in the garage. Afterwards, the readings were random and in the low milliwatts. I think not a coincidence

Random pixelation issues stopped and I haven't seen any screen changes on the NVR since then My gut tells me he is up to something.

Regarding the 420 to 450 MHz readings, I know that ham radio operates in that range and some RF remotes (garage door openers). Older cordless phones and two-way radios also fall into this range. We do have a few hammies in the area and

His other frequencies were in the ISM bands. Also sounds like he is messing with a
Magnetron out of a microwave oven. He might backtrack w/ his 5 Watt reading and
play with RF exposure limits..

At least he will not be "blind" w/o facts.

I wouldn't doubt that he would be messing with a magnetron out of a microwave oven. The question is, is it illegal to do so, and if so, how does one prove what he is doing? And just what are the limits?

On a side note, our digital TV with OTA antenna has certain stations that freeze and pixelate at times. Not sure if there is a correlation, but I thought it was worth mentioning

5 watts, if accurate, is a very large issue. When you post results could you please include the model number of the device you are using and a screen shot of the levels being displayed?

I'm using a GQ EMF-90. Tried to upload a photo and it's not letting me

So you are implying that he turned off the jammer after you walked around with the scanner, like he was covering his tracks? How would he know that is what you were doing? Could he observe you with the scanner? Could he tell that it was a scanner?
