The invention discloses an antitheft 
protection system for a garage. The 
system comprises a 
dynamic monitoring module and a prompting module, mutual 
data transmission is conducted between the 
dynamic monitoring module and the prompting module, the 
system also comprises a control module which is capable of controlling ascending and descending of stopping blocks arranged around a vehicle parking position via an execution module, the 
dynamic monitoring module is used for sending information to the prompting module and the control module after a movement amount is detected, the prompting module is used for sending signals to a 
mobile end and receiving feedback from the 
mobile end after receiving the information, and feedback information is sent to the control module for 
processing. The garage is monitored via the dynamic monitoring module; when movement of a 
human body heat source in the garage is monitored via the dynamic monitoring module, information is sent to the prompting module and the control module, then the information is sent into the 
mobile end via the prompting module, a condition in the garage can be remotely observed via the mobile end by a user, and the condition in the garage can be clearly monitored when no 
light source is available due to adoption of an 
infrared thermal imaging camera in the dynamic monitoring module.
