Buyer's Guide: Best Motion Detectors
This is why we want to offer you our guide to buy the best motion detector in the market, with some practical and simple guidelines to know what you should look for.
Detection capability
The first point by which any comparison of motion detectors is distributed is the detection capability. It is not the same as a product designed for a small bathroom from one public place to another for a large store or similar. Therefore the capacities must be adjusted to what you need, more considering that this point is key when establishing the difference between how much a detector or other.
When talking about detection we have two main elements: distance and angle. On the side of the distance, this is the separation in meters at which the detector can detect the movement.
Generally, this part of the 3 meters, although in the most advanced models it can reach 15 meters. Obviously, they are not cheap models, so do not overdo the search. Regarding the angle, this is the area in which the detector searches for what it has to detect.
Just as a camera has a certain capacity or angle to take a picture, the same thing happens to the detector. Again, it is our needs that have to guide us, although placing the detector correctly on the passage areas is something that helps improve detection, even with a detector cheaper than expected.
Electrical capacity
The second aspect we are going to consider regarding the detector has to do with electrical capacity. In practice, what the detector does is give the order to turn on any equipment, usually lights, but it can also be a fan, air conditioning, screen, etc. Therefore, the power or ignition capacity of the detector must be in line with what we need.
In this regard, we will make two sections. In the first, we talk about lighting. The detectors usually have different levels of power or capacity depending on the type of lamps used. So it is usually normal to find a power for energy-saving lamps and another for conventional incandescent lamps. Keep the levels in mind to see that they really adapt to your specific needs.
In case we use the product for the activation of electrical equipment, the capacity of the product must be adapted to the need for a power supply of these. If it is true that the capacity saved high-cost equipment, it will not be high, but generally enough for these uses. Keep this in mind, if you are going to use them for this purpose, the restrictions are higher.
Frequently Asked Questions (FAQs)
1. What does a motion detector do?
A motion detector is an electronic device that uses sensors to detect nearby movement. It is an important component of security systems and sends alerts to your security system or mobile phone when motion is detected.
2. What are the two types of motion detectors?
There are two types of motion detectors: passive and active. Passive systems wait for changes to occur, while active systems measure the presence of objects by sending and receiving signals.
3. What is the difference between a motion detector and a presence detector?
A motion detector is less sensitive and designed to detect larger movements, like an arm. It is suitable for high traffic areas. A presence detector is more sensitive and can detect finer movements, like a hand.
4. Do motion detectors need wifi?
Motion detectors can use Wi-Fi or cellular networks for communication in wireless systems. Wired systems may use landlines or ethernet cables.
5. What triggers a motion detector?
Motion detectors detect changes in infrared energy, which humans and animals emit as heat. When someone approaches the sensor or walks within its range, an increase in infrared energy is detected and an alarm is triggered.
6. What is the most common motion detector?
The most common motion detector is the passive infrared (PIR) sensor. It detects body heat by looking for changes in temperature and is widely used in home security systems.
7. What can trigger a motion sensor?
Outdoor motion detection lights can be triggered by passing cars, approaching visitors, rustling leaves, or even bugs or spiders crawling across the sensor.
8. What are the three types of motion detectors?
The three main types of motion detectors are active, passive infrared (PIR), and combined. Each type has its own role in different security or safety situations.
9. Do motion sensor cameras record all the time?
Most home security cameras do not record continuously. They use motion detection to start recording when motion is detected, which helps save storage and avoids uploading large files to the cloud.
10. What are the disadvantages of motion detectors?
Some disadvantages of motion detectors include potential harm from high-power radio frequency (for active type), limited penetration of radio frequency in microwave range (for active type), and passive sensors not operating above certain temperatures.
