One of my customers needs to deploy some covert cameras (Axis P1224) in his large warehouse sized refrigerator. The temps in one cooler can be -12F and the main cooler is around 20F. Not sure if he is going to deploy in the -12F cooler, if so I might have to look at different options.
I need to power these remotely with a battery power supply. Ideally, we would like to get as much recording time as possible. I will be powering these with the secondary power input - I have 8-28VDC 4.5W max to work with here.
Are there existing battery power supplies available already for this application? I'd like it to be somewhat modular and easy to change and charge batteries. The entire deployment will be moved around quite often.
Suggestions for this application? I don't know if I need to be looking at SLA or Li-ion...?
Thanks in advance.
