Product Description

The Old Way: Alarms for Everything

Old overhead antennas read tags. That's it. Tag passes through the door – alarm sounds. Tag moves outside to inside – alarm sounds. Tag moves inside to outside – alarm sounds. Everything triggers. False alarms everywhere. Staff ignores them. Real theft gets lost in the noise.

The LFM-DZ003 Overhead Antenna Way: Alarms Only When It Matters

LIFANGMEI built the LFM-DZ003 Overhead Antenna to solve this problem. It doesn't just read tags. It tracks tag movement direction.

Tag moving from inside to outside? Alarm. That's a potential theft.

Tag moving from outside to inside? No alarm. That's just a customer walking in.

Two Key Advantages Over the Old Version

Advantage Old Version (LFM-DZ001) LFM-DZ003 Overhead Antenna

Alarm Zone Control Less precise – alarms for any tag More precise – fewer false reads

Tag Movement Direction Cannot recognize direction Recognizes direction – ignores outside-to-inside

Store Display Products must be kept further from door Products can be displayed nearer to the door

More Features, Better Connectivity

High-gain antenna – stronger multi-tag identification
