DIY Home Security System: The 5 Must-Haves from Amazon


Has anyone else watched way too much Law and Order SVU over the years? I 100% have and now have an unrealistic and overactive imagination about all the ways someone can break into my house while I’m peacefully sleeping at night.

Luckily, since college I’ve either lived with roommates or lived in an apartment complex with neighbors all around me, so I’ve been able to keep this paranoia at bay. Until recently…

I’m now living by myself (with my 5-year old) in an actual house, with a basement and an attic and all kinds of ways to break in.  So instead of staying scared and avoiding going down to get a glass of water in the middle of the night, I decided to turn my house into a mini-Fort Knox on a budget. And now I really can sleep much better.

If you can relate to this at all, check out the 5 key pieces of my DIY alarm system that I put together in a couple of Amazon orders:

#1: Self monitored security alarm: BIBENE 2.4Ghz WIFI Home Security Door Alarm System

What I like about it – It comes with 2 remotes. I keep one on my key chain and one on my night stand so I can easily turn off the alarm off if I get home from work early and turn it on manually if I go to sleep sooner than when I have it scheduled.

I also really like that it has an app that I use to manage the on/off schedule based on when I go to bed and wake up and leave and come back from work. It’s also what you’ll want to look if/when the alarm is triggered so you can see what sensor was tripped. I numbered each of my alarms and then listed in a notepad beside my bed so I can see what number is associated with what window or door.

Cost: $69.98 - The one I got here.

# 2: Wyze Cam 1080p HD Indoor Wireless Smart Home Camera with Night Vision, 2-Way Audio, Works with Alexa

For what you get, these are an amazing deal and super easy to install.  I would recommend also getting the SD cards (they do not come with it), so you have the ability to play back footage if needed. 

What I love about it – It too has an app that lets you see all your camera views in one simple page. One night my alarm went off, which obviously sent me into a panic, but I was able to pull up my phone to see what sensor was trigger with the alarm app and then pull up the live stream on my camera app to realize it was just my alarm had fallen off the wall.

Even if you lived in an apartment and you just wanted to put a couple around key spots, the doorways or easy to access windows, these would be great for that as well. I currently have 3, but am wanting to get a few more for around the back of the house (there is outdoor protection you can get for them). 

Cost: $25.98 - The one I got here.

#3:  Ring Wi-Fi Enabled Video Doorbell in Satin Nickel, Works with Alexa

I know a lot of people get this to help deter Amazon package theft, which I do like with this, but also, it’s nice because you can see who’s at your front door before you open it whether you’re home or not and if needed, speak to them through the unit. 

What I like about it: I will also use  the "Live View" occasionally if I hear any "weird" noises while I'm getting ready for bed upstairs. It just lets you pull up a live stream of what's taking place on your porch and/or street. Luckily, all have been false alarms, but it's nice to have the option without having to physically go down and check it out when I'm terrified.

Cost: $99.99 - The one I got here.

#4: Mr. Beams MB333 Wireless LED Spotlight with Motion Sensor and Photocell, White, 3-Pack

I have several of these set up outside in the front and in the back in spots where people might think they could break in, but the light goes on within a certain range. 

What I love about these: They’re not hard to install, especially if you have a power drill and the range of motion for the options of how far out or in you want to set them at is pretty wide. 

Cost: $36.22 - The one I got here.

#5: Defender Security U 10827 Door Reinforcement Lock

Again, in my overactive imagination, the way someone breaks in in most scenarios is through my basement door, so I bought one for that as well as my front door because I wanted one more extra lock...

These are a little tricky to open at first, but once you figure it out it’s easy peasy. Also, where you install them along the door frame does matter so be sure and read those instructions.

What I love about these: My uncle who’s a cop told me before that these were legit so I feel like that’s a good enough endorsement for me. 

Cost: $17.90 - The one I got here

Bonus: Door Window Privacy Stick-on Coverings


While I wouldn’t necessarily call this a “security” item, I did recently put these up at my front door where it’s mostly glass and has window panels on each side that are also almost entirely glass. While I love the natural light flooding in and even though we set up a bit on a small hill in the neighborhood, I constantly felt exposed going anywhere in the foyer and dinning room area.  These made me feel way less worried about walking around the front  of the house in my PJ’s and actually made that area pop a bit and look really pretty. 

What I love about it: They are so pretty when you get them up and they are super super easy to install. 

Cost: $23.99 - The one I  got here.
