Low power consumption network camera system and portable low power consumption IP camera

The invention is applicable to the field of IP cameras, and provides a low power consumption network camera system and a portable low power consumption IP camera. The low power consumption network camera system comprises an IPC (IP camera) main module, a WiFi module, a PIR (passive infrared) module and a power consumption control module that is connected with the IPC main module, the WiFi module and the PIR module separately; the power consumption control module is used for sending an outage control signal to the IPC main module to enter a lower power consumption state when the power consumption control module receives a job done notice from the IPC main module so as to enable the IPC main module to be in outage and closed; and when the power consumption control module receives a triggering signal sent from the WiFi module and/or the PIR module, the power consumption control module enters a normal work state and sends a power-on control signal to the IPC main module so as to enable the IPC main module to be powered on to run. According to the low power consumption network camera system and the portable low power consumption IP camera, due to the adoption of the power consumption control module, the consumption control module can perform comprehensive control on the power consumptions of the IPC main module, the WiFi module and the PIR module connected with the power consumption control module, so that the power consumption of the network camera system is greatly reduced, and the cruising ability of the IP camera powered by batteries is greatly improved.
