MOTION SENSOR ALARM SYSTEMS. INDUSTRIAL SECURITY TRAINING.
Motion Sensor Alarm Systems
- Motion can be detected by measuring change in speed or vector of an object or objects in the field of view. This can be achieved either by mechanical devices that physically interact with the field or by electronic devices that quantifies and measures changes in the given environment.
- A motion controller controls the motion of some object. Frequently motion controllers are implemented using digital computers, but motion controllers can also be implemented with only analog components as well.
- (MOTION SENSORS) This refers to a family of INPUT DEVICES designed to detect movement within a specific field of view or detection pattern. Most MOTION SENSORS use one of two detection technolgies: passive infrared, and microwave.

- (alarm system) alarm: a device that signals the occurrence of some undesirable event
- (alarm system) Warning devices, installed or free-standing, including but not limited to: carbon monoxide detectors, flue gas and other spillage detectors, security equipment, ejector pumps and smoke alarms.
- (Alarm system) Burglar (or intrusion), fire, and safety alarms are electronic alarms designed to alert the user to a specific danger. Sensors are connected to a control unit via low-voltage wiring or a narrowband RF signal which is used to interact with a response device.

Kaitlin and Sammie
For this portion of our New Year’s Eve photoshoot, we traveled a few blocks to Chandler High School, which we assumed would be entirely empty. Moments after I took this picture, however, the custodian emerged, looking a bit puzzled, and he told us we had triggered the building’s motion sensors, which in turn had activated the alarm system. He was nice about it, though, so we apologized and adjourned to a tree a few yards away, where we not only finished the shoot but had what all three of us agreed was the best part of it.
Coat closet
This is the coat closet at the top of the entry stairs. Plus a motion sensor that I assume goes to the alarm system.
