It seems to hold a really decent amount of clips and how old they are doesn’t seem to matter, it is more based on how many activities you have saved it seems. I have seen some fall off the bottom of the list after I had quite a large number on there. It is very easy though to download the clip to your device and store it forever. When it is something I want to keep I just save it then I don’t have to worry about it being erased with time. To be honest most videos you will not have a need to store to your device unless it is something suspicious or you want to be funny and send friends/family videos of themselves!Also just a note that downloading it does not remove it from their cloud, it will still stay and you can continue to download on other devices, etc. Integration'sIFTTT – I have hooked this up with my Nest Protect and Alexa channels. It works exactly as advertised. You can record video, change the color of the LED, and turn on and off the chime with Alexa. Echo – This is a recent addition that I am loving and am using mostly in place of IFTTT. We have a small toddler at home who still takes naps and the ability to ask Alexa to tell SkyBell to turn on quiet mode turn off bell is such a great feature. No more little signs on the front door saying “Baby Sleeping”, just tell Alexa and the doorbell is off while your child sleeps in peace.
