I have a smoke detector on a 24 foot ceiling that is not accessible other than with a large a frame ladder. It is in a non-occupied non-bedroom. When the battery gets weak and it starts to beep, i won't be able to get to it. I would like to disconnect it but am concerned that if I do it may effect others.
I suspect that regardless of the out come that YES a civil suit will be filed. And since you brought up oj, I remember when Barry Sheck was asked how oj was found liable/guilty in the civil case and not in the criminal case, with out bating an eye stated matter of fact, This jury was allowed to see more evidence. Kind of makes a person wonder about the quality of the US justice system.
Sensors There are basically four types of sensors used in motion detectors spectrum: Passive infrared sensors (Passive) Looks for body heat. No energy is emitted from the sensor. Ultrasonic (active) Sends out pulses of ultrasonic waves and measures the reflection off a moving object. Microwave (active) Sensor sends out microwave pulses and measures the reflection off a moving object. Similar to a police radar gun. Tomographic Detector (active) Senses disturbances to radio waves as they travel through an area surrounded by mesh network nodes. Dual-technology motion detectors Many modern motion detectors use a combination of different technologies. These dual-technology detectors benefit with each type of sensor, and false alarms are reduced. Placement of the sensors can be strategically mounted so as to lessen the chance of pets activating alarms. Often, PIR technology will be paired with another model to maximize accuracy and reduce energy usage. PIR draws less energy than microwave detection, and so many sensors are calibrated so that when the PIR sensor is tripped, it activates a microwave sensor. If the latter also picks up an intruder, then the alarm is sounded. As interior motion detectors do not ‘see’ through windows or walls, motion-sensitive outdoor lighting is often recommended to enhance comprehensive efforts to protect your property. False alarms are those usually caused by technical errors such as electrical and mechanical failures. Nuisance alarms are system activations not commonly caused by attackers or intruders but rather from wind blown debris, animals, insects and foliage. Sequencing alarm systems to trip the alert mechanism only when both alarm sensors have been activated will reduce nuisance alarms, but may also cause the probability of detection to decrease.
