What are the advantages and disadvantages of the battery -controlled motion sensor?
Motion sensors are small devices that monitor movement in a defined circuit. These devices are available in solar, electric or battery units. The driven units can only be used near buildings and cars that have access to electricity sources. The battery motion sensor is more compact and can be used in remote places where no energy source is available.
For most residential applications, a solar motion sensor is available. This form of sensor requires an adequate source of sunlight to function properly. Solar driven units are cheaper than other units, but may be broken with a cloudy cover or poor weather. These batteries usually last a few months before they need to be replaced. When using a unit of battery operated, charging batteries will be cheaper over time.
Corrosion is the greatest interest in the tbullia has operated a unit of motion sensor. This form of motion sensor is exposed to water, heat and naturalthe elements that cause the batteries to deteriorate rapidly. These types of sensors require periodic control to ensure that the batteries are in good operating condition. The inability to see the battery could result in deterioration of the entire sensor compartment acid, so it is completely non -functional.
Electric motion sensor requires low voltage electrical source. This type of unit usually requires manual excavations of the electric line in the yard. This form of the electric line takes several hours because the line must be buried and connected to the electric output. Most electric motion sensors are used inside. It can usually be found in banks and museums to discourage future thieves.
Battery controlled motion sensor transmits information from the power line. It is easier to configure and requires minimal installation equipment. Most units controlled by batteryI includes a simple sensor and receiver device. These units can be installed in minutes.
The battery -controlled sensor can only transmit signals of about 400 yards (approximately 365 meters). This usually provides sufficient coverage for most supervision systems. Longer range systems are available, but require more energy to send a stronger transmission signal.
Hybrid motion sensors driven by solar solar devices provide a method of constantly charging the batteries of the unit. These devices use a solar panel to provide a low charge for the unit charging battery. Hybrid units are usually more expensive, but provide added long -term battery life, which is more cost -effective for the motion sensor of the battery operated.
