When I am in "remote mode", the video stops after 5 minutes. Microwave sensors consume more energy than PIR sensors. Ultrasonic sensors, meanwhile, are highly suitable for spaces in which a line of sight is not possible, such as partitioned spaces, and in spaces requiring a higher level of sensitivity. By knowing the difference between PIR sensors and microwave sensors, you can make the right choice when looking for new lighting. 1. PIR-based Motion Detection: In this case motion is detected by means of a PIR sensor, a passive infrared sensor. The sound alert setting threshold is not right. When the beam is cut (break) by the objects, then it will trigger the alarm. 4.

I do not hear any sound when I am accessing a remote Camera. 2. microwave detectors also have some negatives. 15 Applications Using Ultrasonic Sensors: What Are the Benefits of a Microwave Motion Sensor? How long will a motion-triggered video record for? 3.

Issues that might complicate their application include low levels of motion by occupants, obstacles blocking the sensor’s view, and sensors mounted on sources of vibration or within 6-8 feet of air diffusers.

Passive Infrared (PIR) sensors work by detecting the presence of heat energy in confined spaces. Microwave detectors can be used in virtually any environment, including those that are not otherwise hospitable to sensors, such as high heat environments that can set of photo-electric sensors.

Microwave sensors are slightly costlier compare to PIR sensors. They do have a number of false alarms, as things such as drapery moving could potentially cause problems. Hence PIR sensor may miss out objects. This site uses Akismet to reduce spam. When using active infrared beam detector for outdoor installation, it's must that use the dual beam or 3, 4 beam active infrared detector, muti-beam active infrared detector can reduce the false alarms that are caused by bird, pet, leaf...etc. Active Infrared Beam Detectors are mainly install outside, duo to it adopts transmitter and receiver theory for detection, it's must important that beam can go through the detection area and reach to receiver.

Hence PIR sensor may miss out objects. Microwaves operate differently to PIR sensors, by projecting microwaves, which bounce off surfaces and return to a sensor within the detector. However, one drawback is that PIR sensors require a direct line of sight between the sensor and any motion in order to function properly. The Focus72 allows you to select between two different motion detection methods: Which option is best very much depends on what you are using the camera for and where the camera is pointed at. Traditional motion sensor light comprises of inductive switching plate and lighting source, they are … The Benefits of Motion Sensor …

Microwave detectors can be programmed in a way to reduce the amount of false alarms without having to reduce the amount of correct positives, therefore improving accuracy while also improving upon ease of use. Active infrared Detectors are using dual beam transmission as structure, one side with transmitter for emitting infrared ray, the other side with receiver for receiving the ray, it is suitable for the outdoor point to point intrusion detection.

They also only work at intervals rather than working continuously, by sending out signals and then receiving them.
