A:Answer Hi Rumbles,
It sounds like Canary Flex would work well for you. If you don't need it to record motion, you can maximize your battery life if you set the device to "private" mode with Watch Live enabled. This will disable motion-activated recording while still allowing you to view a live stream.
If you Watch Live infrequently and/or for short periods of time, you can expect your battery to last a month or more. If you stream for hours at a time, the battery will likely have to be recharged after a few days.
If you have any other questions, check out http://help.canary.is where you can find answers to frequently asked questions, or chat live with a member of our customer support team.
