Yes, the Longshot Marksman Wireless Target Camera includes a carrying case as well as a tripod and charger.
The Longshot by Target Vision LONGSHOT Marksman Wireless Target Camera can be upgraded to work up to 2 miles like the LR-3. However, you would need to contact the manufacturer to receive that upgrade. I also recommend contacting the manufacturer in regards to syncing the two cameras together.
This camera was designed for a max range of 300yds. The LR-3 model has a 2-mile guarantee and would be ideal for a 500-yard range.
Long Shot advertises a range of up to 2 miles.
You will download the TargetVision app on your device. From there, you don't need any signal at all. The LONGSHOT system creates its own WiFi network that you will be able to log onto to view the camera stream. When connected to the camera's network, your device will likely say "no internet connection available". This is normal and nothing to worry about, the system will still work correctly.
The Marksman model has a maximum range of 300 yards. There is no flash or IR capability on the camera, so it will be subject to the lighting conditions of your surroundings.
You can absolutely use the camera inside the 300 yard maximum range.
The "W" is just the indication of selecting with or without the Bulletproof Warranty, provided by Target Vision. The Bulletproof Warranty is an option in addition to the Standard 2-Year Manufacturer Warranty.
The Marksman model is 300 yards while the LR-3 is a 2 mile range.
