![]() The VMD option combines the images generated by a security camera, with software that can analyze the images as they are captured. As mentioned previously, there will be differences between PIR sensors at different ends of the market – make sure you choose one that suits your specific needs. ![]() They work well in smaller indoor areas and don’t ‘see’ through windows – a problem sometimes encountered by video motion detection (VMD)And, given that they have been used in security systems for so long, they are also fairly affordable. Negatives aside, PIR sensors are effective provided you are aware of their limitations. Fox etc.) that will trigger false alarms. spider webs, leaves etc.) and passing heat signatures (e.g. In addition, the way in which the PIR sensor operates also means that it doesn’t have the greatest range, and it can easily fall foul of obstructions (e.g. The significance of this will become apparent when compared to alternative technology in this post. For one, the output from the sensor is a very simple yes/no (e.g. This simple technology is effective in what it does, but the simplicity of the design brings with it inherent problems. To learn more about how they work, click here. The sensor detects changes in the amount of infrared radiation it picks up, and when a threshold limit is reached the sensor will trigger whatever it is connected to – be it a light, alarm or camera. Passive infrared (PIR) sensors pick up heat signatures from objects within their field of view. Every installation will come with its own challenges – be they budget constraints or challenging conditions – and each will require a tailored solution to meet the requirements. The below is aimed at differentiating between the benefits of each technology when operating in the most appropriate environment.įinally, and most importantly, choose a solution that fits the specific job. It is also worth noting that within the motion detection technologies I’ll be looking at, there will be significant differences in quality and effectiveness between individual products. So, before deciding on a new component for your system, ask yourself how it will fit into your existing network and whether it will work with components you might want to add in the future. Security systems are at their most effective when made up of a collection of best-in-breed components working seamlessly together. Choosing the right tool for the jobĪn important and often overlooked factor when choosing new components for your security system is how well they will integrate with your existing network. It does not store any personal data.There are many different options for motion detection, but which one best suits your needs? Here I look at some of the most widely used motion sensor technologies and explore the situations in which each can be used to its strengths.

So the information you get isn’t just accurate, there’s also more of it. Plus, it provides exact positions, allowing you to filter on distance. With 120-degree horizontal coverage and up to a 50-meter (164 feet) range, it also delivers the angle of movement, and speed of moving objects. Like moving shadows or light beams, small animals, or insects. It’s not sensitive to things that often trigger false alarms. And it does it accurately, minimizing false alarms – in any weather and at any time of the day or night.ĪXIS D2050-VE Outdoor Motion Network Radar Detector detects movement and nothing but movement, 24 hours a day. Designed as a complement to your video surveillance system, AXIS D2050-VE Outdoor Motion Network Radar Detector uses advanced radar technology and intelligent algorithms to detect trespassers who may have breached your first line of defense to enter your premises.
