Update;
I was able to once again borrow a friends iPhone so I could reset the Altas PT Ultra camera and go through the set up process again.
Once I went through this process, the camera is currently connecting to the Reolink Client on a more consistent basis.

Further Update:
I am still having issues with Altas PT Ultra connecting to Reolink Client. Most times I have to open, close, and reopen client several times before the camera will connect. Very frustrating!
I recently added an E1 Outdoor Pro to the client and this camera connects every time I open the client and this camera is located further away from the router and has a weaker Wi-Fi signal!
What is wrong with the Altas? Are others experiencing these issue...or am I alone with this problem?

@joseph_1979 Apologies for delayed reply...I am new here and only allowed 1 post/day! Silly!
The camera is only about 10-12 feet from the router, any closer and I would have to bring it inside. It is mounted under my deck just below where the router sits inside the house. Thanks for the suggestion.

I have just reset and and set up the camera again. I have not been able to try this in the past two weeks, as I have to borrow a friends iPhone, which I had to use to set up the APP, as I don't use or have a smart phone...thus the importance of the Reolink Client on my laptop. 

I may have stumbled across a possible solution today. I will do some testing and give it some time and update here...if it keeps working.

I purchased the new Reolink PT Ultra two weeks ago and I am using the Reolink Client on a Windows 10 Laptop to attempt to view the camera. I say attempt as the camera will not stay connected to the Client.
Once I finally get the camera connected to the Client all is fine...until I close the Client. When I reopen the Client the Altas "fails to connect". The only means to get a reconnection is to delete the camera and shut down the Client, then it takes several, usually at least 6 attempts to add the camera and reconnect to the Client. Both support and customer service have been involved in trying to resolve this issue and have had me going in circles for the past two weeks, with no progress.
Has, or is, anyone else having this connection issue with the Altas PT Ultra and Reolink Client? If so, were you able to resolve?
This is my 2nd Reolink camera, the 1st I had to return as it was not Wi-Fi 6 compatible, and my 1st use of the Reolink Client. Not having a positive experience!

@reolink-daisy I don't see how to set up Pre-record Mode in the Reolink Client. Please provide instruction. Thanks.

I specifically chose Reolink because it has a client that I can link a camera to my Windows laptop, as I do not have a smart phone.
Imagine my frustration when I received my newly released Altas PT Ultra and could not connect it to my Reolink Client! After contacting support I was informed the camera had to be initialized on the Reolink App prior to connecting the the client! I had to have a friend with an iPhone install the app in order to initialize my camera, then I got it connected to my client. Yeah! The next day my camera would not connect to my client! Now I am being told, buy support, I have to reset my camera, reinitialize on my friends phone, add camera to client then delete camera from client and reconnect to client manually! So now I have to bother my friend yet again!
Please remove the requirement to initialize in App before adding to Client. A previous Reolink Argus Track did not have this requirement or issue!
