Do you have surveillance cameras? A network-attached surveillance camera can consume a sizeable amount of energy. It's not just the camera but also the NAS or NVR for storage, software for image analysis, and network equipment that's loaded continuously because of the recorded streams. Simple tip to reduce power consumption: just store the event recordings on an SD card in the camera unit. It has downsides, but it's very efficient. #energyefficient #nas #surveillance #frugalcomputing #locaverdi
