Questions about this item

How do I mount the CT50D-001 on a ceiling and which step is often missed?

Choose ceiling, wall or desktop placement; the step often missed is setting the 24/7, Day or Night mode and the high or low sensitivity switch before fixing the unit in place.

What power options does the CT50D-001 need over time?

It runs on alkaline batteries or USB power; plan to replace the alkaline cells when the siren volume drops or switch to a USB supply for continuous operation.

At what distance does the CT50D-001 stop detecting motion reliably?

The PIR sensor covers up to 19.7 feet; beyond that range motion may not trigger the alarm or chime modes.
