Advice for PIR motion sensor


I am currently developing a wireless PIR motion sensor for my home with Arduino and I need some advices (I am new with Arduino).

The product will send a signal everytime it detects someone but I need to switch on/off when I am at home.
For instance, before switch on/off on the device, it will detect a movement  (and I don't want to).

Is there any way to switch on/off remotely (right before entering in the house for instance) ?
1/ Infrared ? Is it consume a lot of battery ?
2/ Bluethooth ? Is it consume a lot of battery ?
3/ Other ?

Thanks for your help,
