That won’t really work, you would have to convert the cameras to IP cameras & modify the homebase to be a NVR also the cameras & homebase have a low power 900mhz link, if you turned them into IP cameras the battery would last a fraction of the time
[eufy cam] The big "Range Extenders we need!" Survey ;-)
Radio signals have dramatically improved and more reliable with recent firmware updates. Live video play is still hit-or-miss; but at least motion footages get recorded.

As just mentioned in the forum just now in some other relation, i would like to PUSH this thread after some months, to remember eufy to develop a eufy cam range extender, as pomised, years ago.
I know, will never happen, as their try to develop one failed … but hope dies last!
Ironically, a couple of updates ago I noticed a significant improvement in range and was able to maintain four cameras in locations previously impeded by solid walls. However, the update at the end of May has reversed that and two of my cameras now fail to connect.
Still, I’m getting adverts for products on the app instead. 
Did you try anything other than venting and wishing?
Did you try:
- parabolic dishes
- soldering directional antennas
- shielding
I realise the energy to move finger ends is small, so it is easy.
The energy to move the mind, about 10% human energy, is much higher, but you have 100% control of it, and is far more effective than moving finger ends to change dozens of other minds.
Learn and make your own extender,

I would rather say unconstructive and kind of trolling. Not helpful at all, it is not OUR job to extend the horrible range of eufy cams!
No it’s our job to not buy products.
Simply don’t buy on a promise, it’s your fault for doing that. Buy on what is here now and if they say it can do something now and it doesn’t then its immediate return for full refund.
Loads of reasons why promises don’t transpire, some of them good reasons. Technology you buy is a moment-in-time decision. Technology you intend to buy in the future is seeking out reviewers with hands-on.
The effort to make a vendor deliver on a promise exceeds the effort to avoid promises in the first place.
Simple tip: it isn’t true til someone independent proved it. Regardless of brand.
But who is independent?
Do you think those thousand of influencers and reviewers are?
Not me.
I write as true reviews as possible.
May be this is a reason I am not invited to many programs anymore.
And I dont use social media., that may be the main reason.
If true helpers and their honest, profounded answers are not needed any more,
the frustrated users should ask those influencers at Youtube and elsewhere.
I dont mind.
I am not greedy to get donated devices only to create “beautiful” videos and reviews.

So if you have a problem with a vendor, you should email them privately, this notion you can bully someone in a public forum is not going to work. The ability to resolve issues between customer-vendor is higher when private because it then becomes person-to-person and not public-to-corporate. Companies have product roadmaps, costs, and market analysis which influences them more than anything anyone can type here.
Public forums is for those who own and those interested in owning to exchange information.
Independent good reviewer would be someone who says what they find, and the best ones put in the effort to find as much as possible. It is hard to find a good reviewer, if you reject the ones who keen to do camera panning, unboxing, music overlay and say “powerful”, and narrow to the ones who use meters and make sound, audio, image comparisons, then these forums become much more valuable as we critique to understand the reviewer’s conclusions.
Now to radio transmission extension, well that’s just a matter of find the frequency so you can get the correct length antenna. Half wavelength, so speed of light / frequency / 2. A parabolic dish to focus it needs to be at least that half wavelength.
Moving the homebase to be mid-way between cameras and then using Wifi extension techniques to homebase would be someone can do today and get a resolution faster than forum venting.
I know I have built such antennas for DAB+.
I will take a photo later.
This is a “high class design” antenna.
“single piece”
There are instructions to be found for others who dont know the matter.
To be fair, an antennae in the context of a homebase would involve finding the frequency, nullifying warranty, cracking open the homebase, finding where the Antenna is solder, desoldering, using a shielded (coax), solder it in place, then place an external antennae pointed at the camera.
If you’re not willing to do that, a non-invalidate-warranty would be to use a parabolic dish and simply focus the existing beam from omnidirectional.
The wavelength is still needed to be known, the FCC listing implies a 900Mhz signal?
Depending on what is the problem, could be intereference. So metallic paint between the source of intereference (but again, you’d need at least a wavelength’s diameter to block most). Faraday cage.
FCC:
FCC also shows 902 - 928 MHz
So optimal Homebase 2 non-Wifi to camera antenna would be 0.16cm, it looks a little too short to me?
of course you need the frequency :
DAB+ BR 4 Klassic in München is simple .
Monopole or dipole?
Monopole (simplest) antenna length:
299792458 metres per second / 222064000 Hz / 2 = 0.67 meters unshielded preferably outside at height, and shielded coax from it to your radio.
I built a special one.
Photo tomorrow.
The length you said is correct (as usual) 
Coax. claro!

@professor I think you have the wrong mentality when it comes to a Kickstarter product, we could only go by their false promises
I also think 1 to 1 they will fob you off where as publicly people can unify & apply more pressure on a company
As for doing something about it I did & it make a big difference
Ps it’s 2.4ghz WiFi for cameras, roughly 900mhz to wake cameras for live view & for sensors
I personally only bothered with the 2.4ghz & not had any issues

How so? I never buy anything from kickstarter. As by definition you’re buying promises. Who does that in technology? Logic: why can’t you make it yesterday? What have you not thought of? If you can make it today then it’s trivial, if you can only make it in the future then it contains risk. Worse is to buy risk and spend $$$ on it.
So then that’s buyer beware. How is that then any other fault than the buyer? The seller has a mind’s eye vision but if you believe it, then it’s not their fault, they don’t know if they can make something, if they did know its because they already done it… so not Kickstarter.
In Anker’s case, they got enough cash to make a prototype, alpha test, beta test, launch. Why do they use Kickstarter…? Because there’s a real risk they can’t actually make it.
Issue with a 900Mhz extender is you have to make a 900Mhz receiver (from the camera) a power source and a 900Mhz transmitter. You then caused your own interference as you doubled your use of the 900Mhz spectrum, so then you make all other 900Mhz devices in the vicinity have a worse experience. So you must then add the logic of channel scanning to find least-interference. They probably picked 900Mhz as its able to travel further than 2.5Ghz.
That extender then takes engineering resources from something else, potentially something with a bigger market and, by definition on Kickstarter you don’t have the cash, means the next product competes with past products. A good logical reason to never believe any future product, because the future is uncertain including they thought of a better idea which makes more money and is looking more popular.
So you wish they hadn’t released the cameras & that many companies never have a chance to go past prototype stage?
We should all wait for the biggest companies to become bigger, release items for no one to buy until a few have managed to get them for free then tried & tested for several months?
Also as said above, there’s no need to extend the 900mhz just the 2.4ghz
Ps

True words @Haloweenhamster !
@professor eufy cam is great and most (kickstarter) promises (not all for sure) are kept after 1,5 years now.
So your argument does not apply, because all (most) we knew and got told on kickstarter, is available and existant. But noone could know or even guess that the range of the eufy cams/homebase is so much horrible in a midtown city environment - again: i got maximum of 12-13 meters with just one wall in between!
So that is the reason why we have this thread and survey … by the way … here is the current status of the survey:
75% (!) is a stunner!
And yes, its a shame that a company like anker / eufy isn’t able to develop such a simple and easy thing like a little box which is just forwarding signals … yes … a very simple RANGE EXTENDER! (we ask for, for nearly 2 years now)
They tried it … they failed … they stoped developing it. That’s very sad.
