Car Alarm System Installation

I have 4 sets of the Bose 251 speakers and have loved each installation. I have used them for my whole house audio system (placed under the eaves in our back yard) as well as a 5.1 system setup in a square 4-car garage. The Bose 251's always sound a little better when you add a subwoofer (like my 4-car garage); but for most stereo outdoor applications, a sub-woofer is not needed nor is it practical. The Bose 251's are a little pricey, but they do last a long time due to their excellent build quality.

Good product. Allowed professional installation without potential disruption of car’s electrical system.

I like this uncomplicated alarm system. My last optex 1000 lasted 14 years and that is why I got another one.

Excellent price. Timely delivery. We use them for the fire alarm system as back up power, and we never had any problems in the past.

Arrived swiftly, works as promised. Replacement power for home alarm system.

Orbi has broken barriers in my apartment. I have just upgraded my alarm system, got a ring

[This review was collected as part of a promotion.] After getting the Ring alarm system I definitely wanted to add the Ring doorbell. I bought the Ring Video Doorbell 3 and its the perfect addition to feeling safe in my home and feel confident know that kids will be more time at home. The quality of the videos are great and the features to customize the system is perfect. Its really easy to install as well, just two screws and your done!

I use this for a DIY alarm system in my house. I have 3 sensors connected to one base unit. The base unit is connected to a power source and an external 30w siren. The sensors detect motion...siren sounds. I turn power on and off via smart plug on my phone. Works like a charm. My only concern would be for the durability of the sensors. As can be imagined sensors are usually placed in high traffic areas which means activity happens all day long. If this will affect longevity of the product I do not know, only time will tell.

Product works as it said it would. We have a dog & a cat which have access through a 'doggy door' to the house when the alarm is on & we have not had the system go off with them going in & out the house.

Hello. We just had a power outage today, for 2.5 hours. As soon as the power went off this system kicked on automatically. I knew the power had gone out because this system has a beeping alarm when the unit is up and running. There is a button you can turn off the alarm. The alarm is not annoying - actually reassuring in a way - knowing that the system is up and running. The alarm turned off when the power was restored. All of my electronics quietly transffered back to the electric current in my house. My unit is now recharging again. I have 3 of these units in my house. I've owned them for a few years now. One unit for my internet system - which was up and running during the power outage. Sure I have internet usage on my cell phone, but all of my electronics that use wifi from my internet were also up and running as well - no interference or worrying about not having wifi available (unlike my neighbors). One unit hooked up to my Mac and Echo - both working throughout the power outage (still connected to the internet because my internet has one of these units). The last unit is hooked up to my TV (including Apple TV, a Roku Box, etc...). I've bought smaller units for smaller items that don't need as much power as this one provides. Overall I'm very happy with my purchase (B&H always delivers the best service) and these units have always come through during power outages. I'm looking to buy a few more... Thanks for reading my review. If you are looking for a great unit, you won't be disappointed.
