I currently have nine V3 cameras. All work fine but there is one that struggles to maintain connection. Which Wyze camera (similar to the V3 footprint) has a stronger antenna to help maintain connection. My wifi is fine, I have a strong mesh system and fiber internet. As I said, the other cameras all work fine and have been for years. This one is a problem, most likely because it is at the front of my house immediately outside a metal garage door. I thought there might be a newer camera which has a stronger antenna.
Jon @TheNetGuyDotCom did a good comparison on the reception strength of the last three models: V3 vs V3Pro vs V4.
The V3 is king far away ( 75ft-120ft) but the V3Pro beats it at all closer distances less than 75ft

You may have better luck putting an extender (or better yet, wired AP) where it will give that camera a better signal than trying to find a cam with better reception. They have tiny internal antennas. Other brands do have cameras with external antennas.
A better main router may solve your problem too, or repositioning it/moving it to a higher location.
You may want to simply rotate a camera that is far from the router and working well with the one that is not. I have found some cameras do not have the sensitivity of others.
You can also try an extender, or remounting it in a position that includes less metal.
The tiny internal antenna is no doubt by design: A quarter wavelength is like 1.25” at 2.4 GHz. A V3 is 2” across, so it can easily accommodate it.
But try a more proven camera first.

I have basically the same setup. Left side is a double garage door and to the right is a single garage door. I’m using a V3 and a v4 both outside of the doors. To solve connectivity issues, which constantly changes due to the weather, I ran an AP to inside of the garage and haven’t had any issues.
My setup is i’m running 2 different mesh systems, setup in AP mode. I blanket the exterior to a particular channel, which causes the neighbors routers to switch to a different channel when they periodically check for interference. The 2nd mesh is WiFi 6E, whereas the other mesh is WiFi AC and I have each AP set for AUTO channel selection in the 2.4ghz range. Everything on a wired backhaul.
The AP that you have that is closest to the garage, can you set the 2.4 channel on that to AUTO? If so, try that.and see if signal strength changes.
BTW, i apologize if none of what I said makes any sense… It’s waaaaayyy past my bedtime. Cheers!

Is the metal garage door a new addition? I had an issue when I lived up north. I replaced the garage door with an insulated one. After that the garage door opener would not work.i solved the issue but extending the opener’s antenna with phone wire. I had a couple of inches stick out if the top of the door.
My point is that the door can block a signal. If you can place an extender or a mesh system node in the attic above the garage (if there is one and weather in your area is not too harsh) or next to a window in the garage, etc, you may solve the issue.

Exactly what i did and suggested. Personally i wouldn’t place it in the attic becuase of multiple reasons: heat, roofing nails, flashing, etc… but mainly because of heat. Detrimental to electronics. Wireless is always hit or miss due to the overlapping bands and practically every house has some sort of wifi setup too. Another funny thing is a device can literally be 6 feet away from your AP, node, router, extender, etc. but if it starts raining or humidity is high, etc. like it is in the Sunshine State, it screws up the signal. 
I’ve learned to laugh at stuff like that because it can cause so much frustration.
I always advise people, recording reliability is of extreme importance, go with a wired setup for the exterior because of all the things that can affect wireless signals.
Cheers! 
Having lived in Florida before, I agree. The solution can depend on where you live for sure.
Heat, cold, and humidity can have a big impact if they are severe. Attics can be good places in mild weather if you don’t have a lot of metal there and have some walls. I have dormers that allow signals fairly well.

Wow. I didn’t realize that having the camera outside is so detrimental. It does make sense with our Florida heat. The attic and garage are like a sauna.
I have always placed my cams on window sills but I didn’t realize they were protected so well from the environment. My cams have it good sitting inside with a controlled 77°F environment year round. I was concerned about the sun coming into the tinted windows but I got over that after reading your post. Thanks.

The OP says there is a mesh WiFi in place. I would try adjusting a node or adding another node to see if a stronger signal could reach the garage area.

thank you. That’s exactly the information I was looking for. IMO it looks like I’m ok with the V3. The one camera gives me a little problem every now and then but I can usually get it reliably reconnected (one of… restart the camera, restart the mesh system, restart my modem, etc, Sometimes it’s an easy quick fix, restart the camera, other times it’s an all or nothing solution). Eventually it’s good to go for another month or so, rinse and repeat, Eventually I can reliably stream while in my office. Thanks again for the info.

believe me, don’t put anything electrical in the attic in FL (temps can reach 160 deg.), When I run low voltage wiring through my attic and drop out at various spots around the eaves I run special Marine grade wires good to over 180 deg. Even running direct bury landscape wire is a code violation. I have my mesh node in the adjoining bedroom against the one wall between it, the garage door and the camera (25 feet). It’s just a nuisance at times but not a deal breaker. I can usually figure out a workaround. Thanks for the recommendation.
