Abstract

This invention discloses a monitoring method and terminal using different monitoring precisions. The method comprises: a user sends, to a monitoring terminal, monitoring precision setting information which includes one or more time periods and monitoring precisions corresponding to respective time periods; and according to the received monitoring precision setting information, the monitoring terminal applies, in each time period indicated in the received monitoring precision setting information, the corresponding monitoring precision to monitor a monitored place, and gives an alarm to the user when an alarming condition is met. Using the method of the present invention can enable the user to set the monitoring precision of the monitored place according to the user'"'"'s practical requirement, make the monitoring precision automatically adapt to different monitoring situations, and not only decrease the false alarm, but also make the utilization of the monitoring terminal more convenient and meet the using requirement of the user.
