1.3 Features
Fully embedded design without PHD, stable and reliable system
Comparing the speed measuring system consists of the PHD and digital camera, this series
product featuring the compact design, stable performance and is very convenient to use. It is free
of the PC virus and OS vulnerability.
The DH-HWS200+ series product adopts the Dahua’s technical advantages in the security area.
The host software circuit adopts the mature platform Dahua has already used in the security area.
The hardware circuit is also be optimized and perfected to use in the industry-level or military
level chips, which lowers the system power consumption and can guarantee the long time
running period in the harsh environments. The full real-time embedded operating system and
unique software specifications enhance the system working efficiency and stability. The dual
watch dogs (software and hardware) technology absolutely prevents the system from downing.
Integrated design, compact construction, easy to install, use and maintain
DH-HWS200+ series product integrates the high definition camera, host, LCD, power, speed
measurement radar, storage disk and etc together. The compact construction and integrated
design allows it to be used in either stationary or mobile environments.
Built-in special image storage device, support over 10, 000 offence images
The built-in special large capacity disk meets the requirement of data safety and mobile speed
measurement device. It supports the short-time local storage and data backup. At the same time,
the system can upload the image to the centre server simultaneously to storage, backup and
review, which realizes dual storage at the local-end and the centre.
Narrow pulse light technology
This series product integrates the Dahua self-developed adjustable narrow pulse light technology.
The vehicle driver even can not notice the short time pulse light, which can eliminate the strong
light effects to the driver’s eyes. It can not only clearly snapshot the plate, but distinguish the
vehicle type and the face feature of the driver and passengers, which can provide the irrefutable
offence evidence.
Narrow beam radar speed measurement to enhance the accuracy, effectively hide
from the electronic dog (anti-speed radar detector)
Dahua self-developed narrow wave radar can meet the international speed measurement
accuracy. The narrow beam radar is rarely detected by the electric dog. It can effectively monitor
the approaching and departing vehicles.
Industry-level component and high reliable socket connector
The hardware circuit design adopts the industry-level components. The system is of low power
consumption, high reliability. The built-in Lithium battery can averagely work as long as 8 hours.
The imported reliable socket connector such as Lemo connector and air-level connector further
guarantees the system reliability.
High definition image snapshot

8
There is a 2 mega high definition CCD camera to snapshoot the offence vehicle. System can
overlay information such as the vehicle speed, snapshot time, snapshot position. The built-in
watermark function prevents the vicious image modification, which maximally guarantees the
authentic image.
General management and remote maintenance function
System supports remote maintenance function. Supports the remote malfunction diagnosis,
malfunction alarm and fix remotely, which greatly reduce the maintenance work load.
Extra low power consumption, support solar power
The whole system average power consumption is below 20w, completely support the solar power.
