They announced additional devices over a year ago that were going to be part of their “seecurity system” but that still hasn’t been released. A keypad was supposed to be among those new devices, I don’t remember if they mentioned a fob for your keychain.
There are several other threads about the still-unreleased seecurity system. Other people have requested keyfobs too.
You can use the If This Then That (IFTTT) service to arm and disarm your blink cameras when your mobile phone leaves and arrives at home.
Also it’s possible to use IFTTT to create widgets to manually arm/disarm on both android and iOS devices that can be accessed from the home screen, no need to open the Blink app every time.
There are threads about both functions of IFTTT too.
Snooze implies that the disarming would be temporary. Like if you want the camera covering your garden to disarm for 10 minutes while you walk out there to water the plants or something. You don’t have to remember to re-arm it if it’s only snoozed.
There are even discussions of that feature request in other topics too.
I guess what I’m really saying is, the search function (magnifying glass at the top) is your friend .
