Is there a device that can filter out noise from electrical outlets?

[digicube]

One of my electrical outlet is producing noise on my video capture. Is there is device that can eliminate this electrical noise coming from the outlet? Using a different outlet fixes the problem but I think it's a shame that I can't use that outlet at all. There maybe more in the house too.

Will this surge protector eliminate the noise? https://www.amazon.com/ESP-MFP-1-Surge-Protector-Filter/dp/B00L0JWKYE

or this power conditioner? https://www.amazon.com/Furman-SS6B-Power-Conditioner/dp/B0002D017M

Maybe I need an isolated power supply but can't seem to find one for sale for AC currents.

plug your equipment into a surge protector single power strip or power center - https://www.techhive.com/article/3063590/how-to-get-rid-of-hum-and-eliminate-other-noi...o-systems.html

All my equipment is connected to a Belkin 12-Outlet Power Strip Surge Protector such as this. https://www.amazon.com/Belkin-BE112230-08-12-Outlet-Power-Protector/dp/B000J2EN4S

Thanks for the link. After reading it, it seems my problem is ground loop and it's caused by equipment connect to different AC outlets. I have 2 power strips connected to 2 outlets next to each other. Since they are next to each other, they are considered the same AC outlet, judging from the link you provided. Maybe I should daisy chain the power strips and connected them to one outlet only.

Ebtech Hum X is a little expensive, for a little more I can get a isolation transformer.

DON"T daisy chain powerstrips or plug a powerstrip into a UPS! ! It may cause more electrical interference and it's a fire hazard. If a fire is caused by daisy chaining, your insurance will very likely not allow the claim. As well as any equipment damage claim from the powerstrip manufacturer will be void.

If you need more outlets, get a powerstrip with more outlets.

Edit: I see you're already using a 12 outlet strip. There's a reason that's the max (AFAIK) you'll find on a power strip. Any more devices, even if they're just low power wall warts, need to be on a separate outlet/circuit.

Lots of sites about safety and electrical issues with daisy chaining powerstrips: https://www.google.com/search?q=don%27t+daisy+chain+powerstrips&rlz=1C1MSIM_enUS785US7...hrome&ie=UTF-8

No, you are looking for what's known as a "power conditioner".

It could very well be Ground Loop Interference

More common know as electrical noise power filter

I just bought this, we'll see if it fixes the problem. https://www.amazon.com/Furman-SS6B-Power-Conditioner/dp/B0002D017M

If not, according to this link I can get a UPS or isolation transformer albeit a cheaper one. https://www.techhive.com/article/3063590/how-to-get-rid-of-hum-and-eliminate-other-noi...o-systems.html

I'm playing from a 3 prong power cable VTR.

This is grounding loop issue, use same phase ans same plug orientation (i know USA plug is coded but anyway check wiring first).
Try to connect equipments enclosure with additional wire so al devices are on same level.
Finally check signal cables, sometimes coaxial cables may have broken shielding (video works trough capacity coupling but with increased noises and frequently hum).
Power inverter (so called UPS only if they are TRUE sine avoid so called modified sine) or isolation transformer are not recommended unless you are aware of all problems they introduce (also improperly use may be dangerous to your live) finally check home/office wiring - for sure may have electrician with decent tester to verify that your power wiring is OK.

Overloading the circuit isn't the only reason to avoid using too many devices on it. All devices, even 5-12V wall warts generate heat in the transformer and cords. One device shorting at the plug or cord may not cause a fire, but it may cause other devices to fail and spark., This is especially true of cheap wall warts that included in many devices.

By design, a spike/surge suppressor is good for one strong spike/surge after which it needs to be replaced. Yes, some strips have a reset switch, but if it keeps tripping, that's a sign that it's done for.

Is it likely more than 12 devices on an outlet will cause a fire? No. Is it possible? Yes. Will your insurance pay if after the fire the inspector says the cause was too may devices on one powerstrip? No.

Don't know I'm not dumb enough to run 1500/2000 watt heater on a one that what cause a fire but it really boil down to house wiring and how many other circuit are tired to one 15 or 20 amp breaker

How is it dangerous and bad?

It depend on weather or not the isolation transformer is ground which what you don't want
Here Vid that explained and demonstration the diff

What happens if you pause the source player? If it continues then is is a hum loop type problem, if it freezes then it is actually recorded on the source material.

[digicube]

Yes the moving horizontal lines continues. Found this video isolation transformers website. https://www.allenavionics.com/categories/video-isolation-transformers

I wonder if they are the magic pill to solve this problem. They are super expensive. $664. https://www.vac-brick.com/products/video-isolation

Is there something with an electric motor on the same circuit or near your capture setup? I seem to recall that this can cause interference with VCRs and TVs. Also, have you tried changing your cables to better shielded ones? Maybe you're getting interference that way? I used to get interference with my VCRs if I allowed the video cables to cross over each other.

What look for is a composite video isolator, go ebay search for Jensen Iso-Max or want that cover both Audio and Video get an RDL EZ-HK3

[Cornucopia]

Furman makes GREAT power products, but I wouldn't expect ANYTHING that costs just $30-40USD to do a proper job of it.

The furman (and other brand) products that I can vouch for cost $180 and up.

You have issue with cabling and power distribution... fixed it. And there is very cheap alternative to expensive galvanic separators - search for CCTV camera balun https://videos.cctvcamerapros.com/uncategorized/cat5-video-balun.html - connect both balun's trough https://en.wikipedia.org/wiki/Film_capacitor (something like PP 4.7 - 10uF) you will have fully galvanic isolation and decent bandwidth for price around 10$

I guess you can search in the direction of audiophiles, these people are queit experienced in that (cleaning mains interference) for their audio equipment.
