eMACROS Wireless Driveway Alarm, Brown

[update 8/27/24] This has been working rock solid - everything I said in my original review is how I left it. No tinkering required except the height (keep reading). I used channel 2 for the chime and it's been a good chime. But yesterday afternoon the chime played and after the chime it said "Channel 2 low battery." I cleaned the solar panel in case there was dirt preventing sun, but this morning it said the same thing. Hopefully after mid-day it will be charged enough to not have the issue anymore. but inside the rubber bottom, ants have gotten into it, so maybe that is causing the issue, or maybe the battery is starting to leak, or an adhesive has melted, and attracted the ants? I'm not sure why ants would want to live in it. It is mounted to a tree, and it's pretty high now, after 2 years of the loblolly pine tree growing, and the pines getting thicker, maybe the sun is having a hard time hitting the panel. I had to put the sensor up high (7ft) and angle it down at the driveway to keep the lawn mower from setting it off over and over again. My Htzsafe sensor/alarm lasted three years, so hopefully this one is not going out after just two years. There was no rust or corrosion that I could see when I sprayed ant killer on it, hopefully not causing corrosion. I have the second sensor charging so it's ready to swap if needed, but I paid $60 for one Htzsafe and $100 for two eMACROS. I like the extra range on the eMACROS (I put it further up the driveway), but not if they die every two years. [original 10/10/22] My main concern is the bottom flap. Will the micro USB port and the toggle switches rust out? We shall see. Several hours in and it's working perfectly! I wish they would add a dial that would let you select one of 20 chimes. Full review: For the past 3 years, we have been using the Htzsafe 1/4 mile driveway alarm. This 1/2 mile range is better. There's a bunch of walls to go through, so I'm sure neither will go the rated distance, but at least these are not arbitrary numbers. This eMACROS is longer range than Htzsafe The Htzsafe only has a single button on the sensor and was very finicky to set the range (it was also used for on/off and pairing). The toggle on this eMACROS was appealing to me for that reason. But, it's a possible point of failure. So we shall see. However, the Htzsafe had 50, 30 and 25 foot ranges, this eMACROS only has 20 and 30. I'm not quite sure what I had the Htzsafe set to lol it was so finicky, I just know it was not enough out of the box and I had to turn it up, and after several tries it worked better. So far the 30 feet range is working well, and my driveway is about 30 feet wide. The Htzsafe hung directly on the outlet which was perfect for me, but this eMACROS has more options, you can put it anywhere, and it can be battery-powered. So I found a different place to put this eMACROS since it can't hang on the outlet, and it's fine. It does have an eye hole to hang it on a screw so it can be hung, just not directly on the plug. The Htzsafe had more chimes. The receiver only had 2 buttons, but that was okay, following the instruction manual (don't throw that away on something with so few buttons!) I could change the chime, some were longer some were shorter. It appears this eMACROS only has one chime per channel. So if you put 4 sensors on this receiver, you have no choice of chime. The main thing I want to change is how calm it is, and how long it is. Maybe some toggles to change that for a future version? Mounting this thing to a tree was weird, but if you watch the main video (for now - amazon pages change over time) they show rotating the sensor 45 degrees so you can get a screwdriver to the mounting hole. I didn't think to do it that way lol. I'll leave it at that. The Htzsafe was much easier to mount and seemed too loose, yet it never fell/sagged for 3 years. Both work, but if you plan on moving it all over the place and readjusting until you get it within an inch of where you need it, the Htzsafe would be easier in that regard. The Htzsafe also used a standard ball so you could use other mounts. This one looks like it uses a ball, but it's not a ball and socket. it actually has a screw holding the 'ball' on, there is no socket. You can loosen or tighten the screw, but you have the unmount the square plate to get to it. This one basically is made to aim straight ahead, and that's all I need unless it starts having issues.
