Driveway Alert Sensor Is Not Working Properly
A driveway alert sensor may produce false alarms. This can happen for a variety of reasons and is more common with motion detection than with magnetic probes or air hoses. When properly setup, few false alarms should be presented, but there may be the occasional false alarm that is problematic for home and business owners alike.
1. There is Too Much Distance Between the Transmitter and Receiver
There is always a maximum range listed for a driveway sensor. When a sensor is not working, it is likely that the maximum range has been overlooked. The only solution in this case is to move the receiver and transmitter closer together.
If the receiver must be further apart, you will need to buy a unit that has a longer range.
2. The Batteries are Dying
When the batteries are dying or the power source is intermittent, the unit may not work properly. The most common issue seen is that you will not be alerted properly, which will negate the reason for having a driveway alert sensor in the first place.
Most units come with a battery monitor and will alert you when a battery is low.
A good rule of thumb is to change your batteries before they get too low. This should occur every 6 – 8 months on average. Even if the battery is stated to last a full year or more, an early swap will allow for uninterrupted monitoring.
3. There is No Clear Line of Sight
Trees, bushes or buildings can get in the way of the signal to the receiver. While some models are better at producing a strong signal, virtually all manufacturers recommended a clear line of sight between both devices.
The signal needs to be able to reach the receiver. Removing a tree may be a possibility, or changing the location of the transmitter is another option.
4. Sensitivity is Too High
False alarms are very difficult to assess. Sometimes, an alarm will go off because a deer ran through the perimeter or because a neighbor ran into the monitoring zone. Infrared motion sensors are very fickle, but you can often lower the sensitivity level.
The goal is to be able to detect vehicles or people, but ignore small animals in most cases.
Adjusting and testing your sensitivity level is always recommend and will allow for optimal monitoring results at all times.
5. Temperature Minimums or Maximums Exceeded
There will be a temperature range that is present in the alert’s description. This rage is often ignored, but it is there for a reason. In frigid temperatures, these units have a tendency to act up and produce false alarms, or not work at all.
A driveway alert sensor should be purchased that has the desired minimum and maximum temperature levels for your region.
Proper setup and an optimal unit will correct most issues you may experience. If a unit is still not working after the above recommendations, it may be defective, or a professional installation may be required.
