I have mentioned this several times. It makes SO much sense.

I also think there is no reason not to have SETTINGS for several parameters.
"Prerecord", for example, seems to be a fixed number of seconds or none at all.
The user should be able to set up to some maximum value, say 0-20 seconds.
Post record is the same.

I finally solved the "flying insect problem" by purchasing separate Infrared LED lights and placing them 6-8 ft. away from the camera. Bugs are drawn to them and do not appear to be BIG BRIGHT OBJECTS to the camera.

I believe under Profile... Settings (gear symbol) there are options for what notifications to receive.

I believe that all important settings are kept on the cameras themselves. When the Client program starts on the new computer, it will scan the LAN looking for cameras and import the settings from them.

I agree with Fiona that FTP is based entirely on the server IP address. When the server is on the LAN, FTP will not attempt to access the internet.
(caveat: I have no NVR. My individual cameras FTP motion recordings directly to the LAN FTP server.)

On the cameras, there is an option in the FTP setup to "Test" the FTP settings. Took me several tries to get the FTP logon information/password/directory parameters correct.
Should be relatively simple to do a "Test" with a live internet connection and also without a live internet connection.

Absolutely. I have two "battery" cameras that are USB powered. The battery cannot possible run down, so this alert is not useful.

I know of no method to set a constant FTP file name on the Reolink RLC cameras. (Battery powered cameras do not support FTP at all.)
(Lack broad experience with web cams, but some brands such as Wyze and Arlo also lack FTP.)

The effect you seek may be possible some other way, such as:

• Have an app that watches the FTP server and when a new file shows up, erase the previous file and rename the new one.
• Use something besides FTP to gather images from the camera. For example, this article describes how to load JPEG images to a web server:

support.reolink.com/hc/en-us/articles/360007011233-How-to-Capture-Live-JPEG-Image-of-Reolink-Cameras-via-Web-Browsers

I agree. Would even go so far as to ask to be able to specify the notification sound for each camera and the volume level.

Click on the Plus sign ("+") and the Reolink Windows Client application will automatically search the local IP subnet for cameras and display any that it finds.
To add cameras that the program does not find on the local network, enter the UID code for the camera in the box and the program will search the Reolink "Cloud" for the camera, similar to the way the Reolink Apple or Android app does.

My guess: People will be ice skating in.... (that place) before Reolink releases a camera with PowerLine built in. That's not their 'niche'.

A substitute would be either:

• Comtrend PG-9172POE Powerline Ethernet +PoE Adapter ($70US) which bundles Powerline and a PoE injector into one box, or
• A Powerline adapter plus a PoE injector (these are really cheap).

Would you mind sharing the reasoning for not using Google to watch for and notify of new Reolink app versions?

Agree. Goofy.

The original Argus uses a 1/4 x 20 screw (standard camera fitting).

This may be a situation where Reolink support has to become involved. Even if a hardware rest is done on the camera, there is a good chance that the camera UID remains in the Reolink "cloud" tied to a specific User ID. That would mean creating a new user account and attempting to add the camera would fail.

Is it correct that you cannot use the app at all? i.e. cannot view the camera? Cannot view the camera settings?

Does "2SI" stand for "Two Factor Authentication"?

To access a Reolink camera, the user must input the camera password. My battery powered cameras* define only a single user account. Even if a person knows the UID (or gets it from the QR code), they have to have the password to log into the camera.

• RLC cameras (not battery powered) allow the owner to define multiple user accounts with different capabilities.

Would it not be better to have an option to allow the user to install any sound file to be what the chime plays? If the user wants to hear an English Butler speak, "There are people at the door." Or to hear a recording of crying babies. Mooing cows. Whatever.

My Argus camera has a setting for "Post Motion" record, that can be set to different values.
Is there a similar setting on the TrackMix LTE?

It is available on Amazon.

The Windows Client shows the E1 Outdoor camera having separate notifications for Vehicle, Person, and Animal. Surely the E1 Pro has similar settings?

Customers have been asking for a Linux version of the Reolink Client from Day One. Never going to happen.

The Argus 4 specifications are pretty clear that the power requirement is DC 5V/2Amp

This means it needs a USB power supply, 5V/2amp that ends in a USB-C connector.
