Project Description
• Customer in Fairfax County was seeking a pilot project to add a visual confirmation of water level at a flood control structure and also to monitor debris loading. Naturally an outdoor camera was the right solution.

Requirements
• Pan, Tilt, & Zoom • High Resolution • Motion and or Still Images • Viewable at night • Low Power – Minimal Solar Panel and Battery • Cellular access viewable through web browsers for
computers, tablets and smart phones • Password protected • Remote activation

Solution
The power consumption of the cellular device, camera, and IR illuminator, was so great, (3amps plus) during operation, meant that the use of the camera would be limited if the solar panel and battery were to be minimal.

Solution • To limit the power consumption of the system, activation of
the camera needed to be customer driven only when needed.
• The Customer had already implemented an ALERT Flood Warning System that included a two way component for activating flashing beacons.
• By equipping the site with a low powered ALERT controller we provided the system operator with the capability of turning on the modem and camera equipment when visibility of the site was needed and keeping the equipped powered down most of the time and drawing no power.

Final Configuration
• User has the ability to turn the camera on and off from the base
station, tablet or smart phone with internet access and browser • Ability to change the settings of the camera for image resolution, and
frame rate • A timer was implemented so the camera and cell modem would be
turned off if inactive for 5 minutes. • A pulse command could be sent to re-trigger the timer to keep the
camera on. • Expandable to have local activation with sensor inputs with settable
thresholds • Full weather station expandable • Full Pan, tilt and zoom capability • IR illuminator has a photo cell so it will only be active during dark
hours, minimizing current draw.

Lessons Learned
• Rain on dome impairs image during storms particularly with headlights shining on it at night. Potential solution – Rainex (for plastic)
• System warm-up time varies but can be a bit over 3 minutes and the wait is frustrating. We are looking at replacing the controller with low power cell modem with control output – always on and powers up camera and IR Illuminator.
