When connecting to an external interface, use an existing
connection terminal, and ensure that the cable terminal
(latch or buckle) is in good condition and properly fastened.
Ensure that the cable is not tense during mounting, with a
proper margin reserved to avoid poor port contact or
loosening caused by shock or shake.
Do not expose but well protect the tail end of the tail cable.
Ensure that the tail cable area is waterproof, and avoid
immersing the tail cable in accumulated water.
Ensure that the voltage of the high‐level signal of the alarm
input interface is lower than 5 V DC when the alarm input
interface is connected.
To keep the housing clean, do not remove the transparent
protective film in the outer layer of the housing during
mounting. After confirming that the mounting is complete,
remove the transparent protective film before the device is
started.
