Support issues

I recently purchased a new Ring Video Doorbell and the 30 day support offered has just ended. Never at any stage in the purchase process was I told that it would be a necessity to have a monthly subscription plan to allow me to see the videos of people approaching my property. This has left my feelings frustrated as all I appear to have purchases is a replacement for my old bell which had no video capability at all. Is it correct that I HAVE to use a monthly subscription in order to really get the benefits of this new doorbell? If so I deal very let down by Ring when I could have purchased another providers product!
