4.0 out of 5 starsEffective, low- cost way to monitor your property
By coachd26 on September 19, 2011
Style Name: Motion Alert Kit Verified Purchase
Recent thefts in neighborhood made adding some security necessary. We were looking for a means of being alerted to potential intruders on the property before they could approach the house, as we live on 5 wooded acres. I also was looking to monitor some outbuildings on the property. We purchased the Skylink long-range system with 3 additional sensors. After a month and some adjustments, the system is performing so well that we have ordered 4 more sensors.

The additional sensors were easy to program, install, and integrate. I have yet to replace a battery. They are remarkably effective for a relatively low-cost yet long-range wireless option. I had to adjust them all to a lower sensitivity setting (an easy jumper change in the battery compartment), as the first few nights they had me up every time the wind blew a leaf. Since adjusting the sensors, I've only been up once a night (take your pick of woodland animal looking at me when I go to investigate). So far, the smallest animal to set off a sensor was an opossum. The sensors do twinkle red when tripped, so you can visibly tell when you've triggered one.

The receiver unit is reliable, but could use a few upgrades. Thankfully, the sensors can be programmed to different zones (up to 4 sensors in each of the 4 available zones for a total of 16). When triggered, the receiver sounds an alert sequence corresponding to the zone that has been triggered and flashes a red LED on the unit in the appropriate zone. There are 3 available modes of operation (Off - which still flashes a visible alert, Alert - which functions as described previously, and Alarm - which would wake the
dead). I'd like to see another alert mode, that would simply chime or chirp only once or twice, and a volume wheel.Read more ›

4.0 out of 5 starsGreat for the price!
By RJPStockton on March 18, 2011
Style Name: Motion Alert Kit Verified Purchase
For the price, the motion sensor works well and definitely serves it purpose. With no range angle given on product, just distance, I was a bit reluctant at first. But the sensor seems to have about 120 degree view so when placed above my driveway and angled correctly, it alerts me to any motion in the driveway. Great ball, snap-on feature secures sensor to the wall bracked and makes installation easy. Base has a chime sensor or an alarm depending on your needs and unit is expandable for up to four sensors for one base unit. I plan to buy more sensors to add to the system. It serves its purpose as a very good warning device at a great price.

4.0 out of 5 starsAn improved edition still lacking one feature
By David G. Wuchinich on April 14, 2011
Style Name: Garage Door Alert Kit Verified Purchase
I purchased the predecessor model which required careful positioning to work reliably and was often incapacitated by rainy weather. This model is so far unaffected by obstructions and the weather, but if you want an audible alert that does not persistently toot at you every second when the door is open that option is not available. The audible alert, whose omni-direction is a real asset, can only be switched either on or off. It would be helpful if this alert could be selected to beep once or twice every minute or couple minutes, providing a gentle reminder of an open door without becoming a complete annoyance when a garage door is left open for a purpose such as yard work or car repair.

1.0 out of 5 starsVery weak/fragile mounting system-Poor warranty service
By Fred on November 16, 2012
Style Name: Motion Alert Kit Verified Purchase
This review is from: Skylink HA-434TL Long Range Motion Sensor (Tools & Home Improvement)
I purchased the Skylink HA-434TL Long Range Motion Sensor system and 6 sensors to monitor a field being sustaining crop damage by deer. I went to the expense to buy and set pressure treated posts so that I could make a metal flashing roof to protect each sensor althouh they are listed as outdoor sensors. These sensors use a 9V battery which with time will of course die and need replaced.

To remove the battery the sensor MUST be removed from the plastic mounting system which is made up of a bracket and a ball/socket piece that attaches to the back of each sensor.
It is NOT possible to remove the battery cover without removing the entire sensor from the mounting assembly.
Yet it is NOT possible to remove the mounting assembly/bracket from the post without first removing the entire sensor from the monting bracket. You can not possibly get to the screws. The sensor must be taken off of the mount-period! My mounts crumbled in my fingers as I attempted to slide them out with my fingers (no tools).
These mounting pieces are very thin/flimsey/brittle plastic. (mine are only 6 months old)

Today I had to change batteries in my sensors. Out of 6 sensors that I attempted to do battery replacements in, 2 of the mounts crumbled in my fingers. Also I have one sensor which has drawn moisture inside of the sensor detection eye and it will not work. A call to the company yielded me being charged $10.98 for 2 mounting assemblies (which is over half the cost of each sensor) and $10.95 shipping for tiny plastic pieces that could be mailed in a padded envelope. The CS rep finally waived $10.98 of that.
Their reason for not covering the entire unit under the 12 month warranty?Read more ›

4.0 out of 5 starsReview
By Stephen Campbell VINE VOICE on December 13, 2011
Style Name: Motion Alert Kit Verified Purchase
For these kind of reviews I like to break it down into parts.

Assembly:

I am not a real smart guy when it comes to assembling anything. First off you will need a battery (9 volt) as it doesn't come with one. I missed that part.

You will need a screwdriver with a little phillips head for the small screw you will have to remove.

It comes with a mounting stand. Screw the stand to something. Slide the ball into the back. You may have to really push hard to get the ball and socket to come together.

When I finished and was sure it was working I scotch tapped the seams to keep out water.

Programming:

Not hard but I had to read the directions three times to get it right. Once you figure it out it is a nobrainer. Just read the part about setting the channel and what has to be pushed a couple of times. Also make sure you put the battery in first.

Use:

It works. My distance is line of sight and 400' feet. Deer set it off. No big deal.

Listen to both of your alert sounds. One is very annoying.

Conclusion?

I like it. No zombie hordes will make it to my front door undetected!
