Under the test mode, one useful function you would like is testing the work area of the PIR
(PassiveInfrared)sensor,specificallythesensingangleanddistance.Toperformthetest:

By doing this test, you can find the best placement when mounting and aiming the Ltl Acorn
camera.Ingeneral,youarerecommendedtoplacethecamera3to6feet(1to2meters)abovethe
