5 out of 5 eggsUpdate for my previous review

Pros: This is an update on my previous review.

The problem with the motion sensor was resolved with the help of Oplink support, which is very good. They replied very fast and provided detailed instructions on how to resolve the problem.

I also e-mailed them directly regarding the problem with the siren being slow and quiet. Got a reply right away again and the representative said that they will send another version of the siren free of charge.

They also addressed the issue of no push notifications on the free account. They said that the new release dated 9/3/14 will include push notifications, which is great!

The best of all this in my opinion is their support. I never had such a timely response. They know how to treat their customers.

Cons: The only complaint that I have now is that if you want to buy additional items for your system, separately they are very expensive. Now, knowing that the push notifications will be added and that their support is so great, I need to get a least two more door sensors, one more motion sensor and I wanted to add two cameras, and that comes out to a little less than $300. Too pricy, but not worth removing any eggs for.

1 out of 5 eggsOne word: BAD

Pros: It looks good. The logo is pretty.

Cons: On the 31 day of owing this system, the motion sensor decided to not work anymore. Can't RMA because it is 1 day past the 30 day return policy.

Besides that broken motion sensor, I would not recommend this alarm system to anyone anyway. There are several reasons. First, it is cheap. The components feel cheap, made from cheap materials, break easily, as seen from my motion sensor that was on the wall from day 1. Second, the alarm siren is too quite, to slow and too winy. Your neighbor would not hear it, your burglar would not be scared of by it. Here is why, before actually going off, this siren starts to beep like a UPS that lost the power to it. So before it actually goes off an intruder has a plenty of time to find it and to destroy it. And even when it goes of, it is not loud enough at all! I have the Rosewill stand alone door sensors that work of two AAA and they are way louder. They are at least two times louder than oplink siren. And the third, probably the biggest reason you should not get it is the way the notifications work. oplink says it is a free system (with no monthly fee), but they only send email notification if you are not subscribed to their premium service. What kind of alarm system notifies you though emails about the intrusion!? I learned that fact only after I purchased it, but you know now. But, currently, I am still on their premium trial and push notifications barely work. Sometimes I get them 5 minutes late, sometimes I never get them at all, even when I am connected to the same wifi network to which their router is connected.

I will have to take of my oplink window decals, because if any burglar in my area knows how oplink works, my house will get on the top of this burglar's list.
Very disappointed.

Other Thoughts: Until oplink replaces their components with a decent quality ones, fixes their push notifications and actually add push notifications to a free self monitoring, this system is useless.
