Project Introduction:


A U.S. Corporation was having trouble keeping up with endless hours of digital video from its 3 dozen cameras placed all throughout its facility. They wanted to streamline the amount of video that was recorded to save disk space and time when video had to be reviewed. Advantech’s UNO-3062 is a reliable, simple, and cost-effective platform to improve the efficiency and performance of camera monitoring system.

System Requirements:

The old monitoring system costs a lot of money and time to maintain. Therefore, the customer needed a reliable, simple, and cost-effective system that would allow connection to a central server and cameras two-to-three cameras per location. It is the requirement to have quicker transmission speed and large hard disk capacity because of video signals. Besides, Linux operation system is required for reliability, simplicity, and security because of security system standard.

Project Implementation:

Hardwares : (for each station)
      UNO-3062 x 1 :Front Access Fanless PC with Two PCI Extensions
    Camera x 1
    Video Card x 1
    Magnetic Door Lock System x 1 sets

I/O list for each station :
      DI x 1 : Door Open/Close Status (onboard DI of UNO-3062)
      DO X 1 : Door Lock/Unlock (onboard DO of UNO-3062)
      Keypad Input X 1: Door Access Password (RS-232 port)
      Video Input : Video Card installed in PCI slot of UNO-3062

System Description:

UNO-3062 connected to keypads as control system via RS-232 port and to cameras via PCI-bus. With on-board I/O, UNO-3062 was needed to tie into the keypad door entry system that was already in place. When the keypad was activated (which unlocks and opens the doors), the camera would be activated. When the door closed and the keypad was deactivated and the door re-locked (meaning the room was empty), the cameras would then turn off, stopping the video recording. All UNO-3062 series also connected to central server which stored all the necessary video through Ethernet.

Conclusions:

Equipped with two PCI-bus slots, UNO-3062 fulfilled the speed requirements to capture the necessary video. Its 2.5” HDD extension offers large storage capacity for video recording. Designed in fanless and compact mechanism, UNO-3062 becomes a reliable and easy-maintain system for building automation. Compared to the old monitoring system, it helps customer reduce the maintenance fee. Besides, it also fulfilled the price-point that the customer was looking to achieve.

The volume of video that is now stored has been reduced dramatically. Now only “action” is captured, and not all the down-time. Plus, UNO-3062 is equipped with on-board I/O which can connect to the door sensor.
Then each video is automatically labeled with keypad code ( which allows them to reference the employee who opened the door ) for ease of logging and future video use.
