Monitors are given back as an asset in your Lansweeper installation, however, they are the only type of asset that do
not count towards your asset limit as explained in
this knowledge base article as janick posted previously.
If you expect to have more than 100 assets in your network environment and want to test Lansweeper thoroughly, you can always contact our sales team (https://www.lansweeper.com/contact-sales/) and request a free trial key for a 30 days period of time, which will allow you to scan an unlimited amount of assets during that time.
