![]() ![]() The security systems available in Australia now start with 4 and 8 channel systems, each with 4 PIR security cameras. In general terms, we can expect the PIR thermal & motion sensor cameras to detect thermal radiation from human-sized and larger subjects within a human temperature range, and it should not detect smaller subjects, such as cats or birds. As it is not technically correct to use the phrase ‘heat detection’, look for the words ‘Thermal Sensing’ on Swann packaging, our website and marketing materials to choose products with True Detect technology. ![]() The word “heat” may create expectation cameras will capture any heat source, like fire or light bulbs. ![]() PIRs detect emitted/reflected infrared radiation. PIR cameras don’t detect or measure “heat”. This DVR combines both technologies: for Recording or Push Notifications both PIR Detection and Pixel Detection must be “true” to ensure maximum reliability in recording and notification. With PIR Motion Detection Cameras, movement means the detection of a warm moving object within the image, optimized for humans, on both temperature range and size. On the scenario below you can see how the Pixel Motion Detection tends to generate false triggers because motion is detected by means of a change of pixels. If everything is working correctly, there is supposed to be a blinking light. You’re supposed to put it in setup mode and set the camera someplace where you can make some motion in front of the sensor. Bushnell 16MP Trophy Cam HD Essential E3 Trail Camera.
