Home automation is the residential extension of building automation.

It is automation of the home, housework or household activity.

Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

2 separate remote controls for 2 separate security cameras. Yet these remote controls interfere with one another. Do manufacturers use generic sensors in most remote controls? (alien.top)

Let's call the 2 cameras A and B. They are not part of a "cctv system".

Yes, they are made by the same company, but they are 2 distinct units.

Yet, when you push the remote for cam A, it sometimes activates cam B. And sometimes, vice versa.

Any solutions to eliminate this type of crazy interference?
I tried searching, but wasn't able to find specific subs that discuss remote control sensors. Any suggestions for suitable subs, to discuss this issue?

Are these IR remotes, like for a TV? Id be surprised if they have any form of channels or isolation, so if the signals are the same, i dont think you can really do anything about it.

One potential workaround would be arranging your cameras in such a way where the remotes signals can really only be picked up by one camera.

Alternatively, since this is home automation, maybe slap a tiny IR blaster in front of each cameras sensor, and program something to control eqxh separately. I think there are a bunch of programs out there that can capture and replicate IR signals

you haven't really given much to go on but a couple of ideas based upon different interpretations:

if your talking about "generic 2.4ghz" check to see if there internal switches to change the frequency range. I have seen stuff that has 2 or 3 "channels" and a little switch on both the device and the remote.

if your talking about some kind of IR remote then the simple solution is to probably solve the issue with line of sight

maybe some more info might help? or if there a reason why you cant reveal much more then work out what you can hint at maybe?

"Yes, they are made by the same company, but they are 2 distinct units."

Yes, this is likely going to be a problem. Not sure why you are using cameras with remotes but point is, if you ever look at a manual for universal remotes, you'll notice some companies that have thousands of products might have 10 codes in that manual. That is because there is a lot of overlap between models. No need to come up with a completely different code set if both products have only play, pause, fast forward, rewind, stop, and power.

What do you mean "generic sensors". Give the brand and model of the cameras.
