The best barking dog alarms on the market can detect movement just as well as a real large dog, however sometimes customers need to detect around metal, or  want to protect locations outside the detection area of the barking dog alarm main unit. Both can be done by adding one or more optional sensors to the main unit.

By adding inexpensive optional sensors that enhance the detection abilities of the main unit, the entire building can be protected.

The sensors match to the dog alarm main unit with a simple one time procedure that insures the sensors only work with that one main unit, or other main units you want to add. 

There are four brands of barking dog alarms that will accept the HomeSafe brand of sensors. The HomeSafe model 639SR; SafeFamilyLife model EWD-1; Safety Technology model EWD-1; and the StreetWise model SWEWD. We covered how those alarms work in a prior post. You can read that post by clicking here.

There are currently three optional sensors that can be matched to the barking dog alarm. Up to 16 mixed and matched sensors or remote controls can be added to each main unit to enhance the protection coverage of the system.


They all work with long lasting alkaline batteries and we recommend only quality battery brands be used to reduce the chance of battery leakage.


Once the sensors are matched to the barking dog alarm main unit the sensors are always on (as long as there is battery power). They will only trigger when the main unit is armed and will cause the main unit to immediately go into its most vicious barking mode, chime, or siren; depending on what you have the main unit set to do. They will continue to trigger as long as there is detection. (Depending on which sensor is triggering). When detection stops, the main unit will reset.



The Window/Door/Vibration Sensor Model 600WR:

This optional sensor has two *plus sensors in one.

To use this sensor, the body is mounted on a door, or window frame where protection is wanted. A wired magnetic contact half is mounted on the door or window frame with the sensor body and the second wireless half is mounted on the door or window.

How it works:

While the main barking dog unit is protecting one area of your building, this unit will protect one additional door or window by sensing any strong vibration, or if the magnetic contact is broken (as if opening the door or window). When triggered it will send a signal the main unit to activate. As long as the contact is broken, or vibration continues, activation signals will continue to the main unit.

There is also a small internal alarm in the sensor body that is switchable to on or off. This switch will only effect the internal alarm and it can be used independently of the barking watch dog alarm main unit.

When we tested the sensor vibration there had to be a hard knock or pounding to trigger and send a signal to the main unit to activate. It did not trigger with a light knock. This sensor is not adjustable for vibration sensitivity and it is designed to protect one door or window with vibration detection, however the magnetic contact is *expandable.

*The sensor comes with one magnetic contact, however a number of contacts can be added in series without the need to add more sensor bodies.

This sensor works with one long lasting alkaline 9 volt battery. Once matched to the main unit, it is always working. There is a LED on this sensor that will blink when the sensor is triggering and it will blink when the battery is getting low.

The Motion Sensor model 615PR:

This non-adjustable PIR sensor is designed to detect movement inside any room, covered porch, or patio area. It can be used within or outside the protection range of the main unit. It can send an activation signal to the barking dog alarm within its radio frequency (RF) range of up to 300 feet unobstructed.

How it works:

This sensor cannot see through objects. Only the main unit can do that, but it can send a RF signal through objects to activate the main alarm unit when moton is detected by PIR.

Once matched to the main unit, it will trigger anytime there is movement within the sensor window of up to 8 meters (26 feet) at 110 degree motion detection angle. We have tested the unit in a number of rooms and when put in a corner,  covered the entire room very well. It will continue to send activation signals as long as movement continues.

This sensor works with one long lasting alkaline 9 volt battery. There is an LED that will flash when movement is triggered and it will flash when the battery is getting low.

The Adjustable Indoor/Outdoor Motion Sensor Model 616PR:

This PIR sensor is the newest and most popular optional add on motion sensor available today. It works similar to and can be used in the same areas as the motion sensor above, however it was designed to mount in areas where adjustment is necessary to hide areas of movement, or reduce detection distance that would otherwise trigger false alarms from any object movement. It can send an activation signal to the main unit within its radio frequency (RF) range of up to 300 feet unobstructed.

How it works:

This sensor is unique in that it is adjustable two ways. There are sliding doors on each side of the sensor to customize angle of detection and a distance sensitivity adjustment is in the battery compartment. These adjustments allow you to block indoor or outdoor areas, such as plants and trees moving in the wind or common walkway areas that you may not want the sensor to trigger on. 

The adjustments also make it the preferred sensor to cover an area where the barking dog alarm can’t be used, such as a metal door or wall. The sensor can’t see through anything like the main unit, however it can be placed on the outside of the metal object and when triggered, send a RF signal through metal to main unit to activate.

The doors on the sides of the sensor can be set from the maximum detection angle of 150 degrees down to just a slit for a very specific detection area.

The control switch inside the battery compartment can adjust the sensitivity or distance that the sensor can see movement. In our tests, the sensor can be set as low as 10 feet and over 30 feet maximum distance. The product specifications show a maximum detection distance of 10 meters, or about 32 feet.   

These sensor adjustments are independent of the sensitivity control of the barking dog alarm main unit. Even with the main watch dog sensitivity set to minimum it will not stop the sensor from activating it as long as the alarm is armed.

This sensor runs on three long lasting AA Alkaline and in our tests they last longer than the Alkaline nine volt batteries of the other sensors. Remember to use quality Alkaline batteries to reduce the chance of battery leakage.

The HomeSafe Remote Control model 500R:

Additional remote controls can be added to allow other family members, or employees to use them with the same alarm main unit.  This remote control is a HomeSafe brand, but it is identical in the way the original remote works with the alarm main unit.

How it works:

Three push buttons on the face of the remote controls Arm, Disarm and Panic functions of the alarm.  More information for this remote is explained with the Best Barking Dog Alarm Post.

These are the sensors and remote control currently available in the USA for the best barking dog alarms covered on this website.
