System Overview

This security radar adopts 24 GHZ radar chip for 24/7 all-weather

high-accuracy detecon in the range of 450 m/90°. It supports radar-PTZ
smart tracking, compable with common Dahua speed domes. With
radar detecon and intelligent algorithms, ultra-low false alarms and zero
missed alarms are achieved around the clock. Mulple PTZ cameras can
be linked to one radar, and wide range global arming and detail tracking

are realized simultaneously.

The product is widely applied to various perimeter and intrusion arming

sites such as farms, prisons, airports, and oilelds to provide users with
safer and more valuable security protecon soluons.

Funcons

K-band Detecon

Adopt 24 GHz radar chip for detecon with long distance, high accuracy,

wide range, and 24/7 all weathers to realize ultra-low false alarms and
zero missed alarms in armed regions.

Radar+PTZ Smart Tracking

Support linkage between radar and common Dahua speed domes.
Mulple speed domes can be linked with one radar (link up to 3 speed
domes on web manager, and up to 8 on plaorm). Both radar and
cameras can be installed separately.

Front-end PTZ Control

Low delay with radar directly controlling camera tracking. Display

radar-PTZ linkage on web manager, and one radar can link with
mulple cameras. Video stream acquision, and map and trajectory
display on NVR or plaorm is also supported.

Intelligent Algorithm of Radar

Support human and vehicle recognion.

Centralized Plaorm Management

Support conguraons and management of mulple radars on the
plaorm. Display radar-PTZ smart tracking on the map.

Protecon and Cercaons

Meet IP67 and IK10 protecon grade, and CE RED standards.

Mul Level Perimeter Protecon

Support region seng with dierent alarm priority, external alarm
linkage, human and vehicle ltering, and vehicle detecon with low and

medium speed.
