 Detection performance is not influenced by vehicles of adjacent lanes, or vehicles from the
front or back side.
 All-weather and all-time.
Detection performance is not influenced by environmental factors such as sunlight, dust,
adverse weather, and temperature.
 High capture rate.
99% (smooth traffic), 96% (saturated traffic), 92% (congestion).
 Precise positioning.
Positioning accuracy of vehicle capture trigger signal: ±0.5m.

3.1.4 Edge Storage Device
This Guide uses DH-ITSE0400-GN5A-B edge storage device. This edge storage device can
encode and decode JPEG and H.264 streams. It has 1T capacity by default, and it is designed
with one built-in SATA interface (supports 2.5-inch HDD) for expanding capacity. The device also
supports ANR (automatic network replenishment), query of pictures and video records, snapshot
and video recording of violations, and more. See Figure 3-2 and Table 3-3.
