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?

Would be interesting to know which brands of battery powered cameras record "pre motion detection"

I have never thought it was a good idea to expose cameras to weather, and mount my cameras "under the eaves" where they will be protected. If you do depend on the weather rating of the camera and the lens gets water inside, contact Reolink for a warranty replacement (as long as the camera is still under warranty).

Please provide a more detailed description of the request.

Push notifications are defined on the camera using either the Reolink Client or the Reolink 'app'. There are no 'ports' involved.

FTP 454 error is saying that the user name used to connect to the FTP server does not have permission to access the directory.

Most Reolink cameras can "change WiFi" after the user connects to the camera and enters the Settings menu.

I use VLC (free for Windows, Linux, MacOS, Apple, Android from Videolan(dot)org.

FTP is a feature built in to the RLC cameras. (not the battery powered cameras). I use it to store recordings from 8-10 cameras using FileZilla FTP server. Provides backup for the camera SD card and (I know this is goofy) allows me to use VLC to view motion recordings.
There are no fees to use Reolink products unless one subscribes to a "cloud storage" plan (I have not)
Looking forward to someone reporting actual temperature experience. My guess is the cameras might function at lower temperatures, but if they don't then Reolink's answer will be "told you so."

Memory is one possible explanation. Another might be that privacy zones are implemented differently for cameras which must be connected to a Reolink NVR to function.

This sounds like a perfect question to ask Reolink support (with an email). I have always received prompt and thorough explanations from them.

@user_858173756547208_858173756547208 How strange. I have set up a privacy mask with over 40 separate zones on an RLC-1212A.

Privacy masks do not have to be contiguous. Each segment appears to be limited to a small rectangle, but there can be dozens of them spread around the screen.
