# Specification / Features
The camera seems to be based on Ambarellas S2 series of IP cameras. Likely a nerfed version of the S2Lm. The power usage is said to be less than 500mW (is it possible to measure this from OSX somehow?).
# S2Lm specifications

* Boot from SPI-NOR, SPI-EEPROM, NAND flash, USB or eMMC
## Image processing
* 3D motion compensated noise reduction (MCTF)
