The Zmodo Greet smart doorbells have five different types of Greet doorbells. The Greet Smart Doorbell which is $89, the Greet HD Smart Doorbell which is $149, the Greet Select Smart Doorbell which is also $149, the Greet 1. 0 Smart Doorbell which is again $149, and the Greet Pro Smart Doorbell which is $179. They also offer three different video recording storage option plans. A Basic plan that will store your alert clips for the past 36 hours which is free. A 7 Day Plan that stores seven days of continuous cloud recordings, seven days of alert clip storage, and it costs $4. 99/mo. or $49. 90/yr. And, with this system, you pay per camera, so this plan gives you 50% off any additional camera subscriptions you purchase as well. Then there is the 30 Day Plan that gives you everything the seven day plan does, except you get those services for 30 days versus seven, and it costs $9.
