All,
In case anyone finds it useful, I did a first run test with this battery:
www.amazon.com/gp/product/B00B45EOYS
I hooked up the TP-Link
TL-WR802N router to its USB port and the
Hikvision 2432 to the DC output port. I then linked the camera to the router, connected to the camera's web interface, and started streaming high-def video at the highest bit rate. I set up a reoccurring ping to the router and then checked how long it kept responding to pings. This was basically a "worst case" scenario for power usage, but I was pleasantly surprised to see that the camera streamed for just over 16 hours before the battery ran out of power.
I also noticed that I managed to buy the older (and more expensive) generation battery, so I'll be returning it and purchasing the
second generation battery which supposedly has about 15% more power and two more USB ports. That should improve the run-time as well.
Thanks everyone!
