A breakdown of the typical home security problems
Published: 16-Oct-2024
When I first started setting up my home security system, some 20 years ago, I thought it would be a pretty straightforward process.
You know, just install a few cameras, maybe a motion sensor or two, and I’d be all set.
Well, I quickly learned that it’s not always that simple.
From equipment selection to camera placement and avoiding false alarms, there are quite a few things that can trip you up along the way.
Trust me, I’ve seen it all—cameras pointing at the sky, alarms going off for no reason, and even dead zones in coverage that make the whole system useless.
If you’re thinking about setting up your own security system or already have one in place, it’s really important to know what could go wrong, so you can avoid the headaches I went through.
I’m going to walk you through the most common home security problems people face today.
Things like this:

I’ll talk about things like choosing the right equipment, making sure your cameras are in the best spots, and how to avoid those annoying false alarms.
Here are the usual home security problems in general:
- Poor equipment choice
- Improper placements of cameras
- False alarms
- Single solutions
- Poor installation techniques
- No backups
- Ignoring cybersecurity
- Poor maintenance and testing
You’ll feel more confident that your home is actually as secure as you think it is — without any of the common pitfalls.
Poor Equipment Choice
One of the biggest mistakes people make right from the start is choosing the wrong equipment.
It’s tempting to go for the cheaper options or assume that any old camera will do the job.
But trust me, the equipment you choose can make or break your home security setup.
Let’s talk about cameras.
It might not seem like a big deal, but if you pick low-quality ones, you’re setting yourself up for disappointment.
You need cameras with good resolution—at least HD—and ideally features like night vision or wide dynamic range (WDR).
Otherwise, you’ll end up with grainy footage that’s useless at night or in areas with a lot of contrast, like sunlight pouring through windows.
Then there are the sensors.
A lot of people grab basic motion sensors without realizing they could be setting themselves up for a world of false alarms, especially if they have pets.
Ever have your dog set off an alarm at 2 a.m.?
Not fun.
Look for motion sensors with pet immunity, and don’t forget about glass-break sensors.
If they’re outdated, they might not even detect more modern threats, leaving your home vulnerable.
Wi-Fi is another big one.
Most modern systems rely on it to transmit footage or send alerts, and if your signal isn’t strong enough, you’ll run into problems.
Ever watched security footage that keeps cutting out or freezing?
That’s usually because the Wi-Fi is too weak. Either make sure your system has a strong signal or invest in range extenders.
Lastly, don’t overlook the power source.
There’s nothing worse than realizing your cameras or sensors aren’t working because the batteries died.
I always tell people to decide upfront whether they want wired systems or battery-powered ones and to be ready for maintenance if you choose the latter.
If you’re going with wired, make sure the wiring is secure and tamper-proof.
For battery-powered options, keep spare batteries on hand or consider solar-powered options for fewer headaches.
Choosing the right equipment isn’t hard, but it does take a bit of planning.
Make sure you’re investing in gear that’s reliable, fits your needs, and won’t quit on you when you need it most.
Improper Placements of Cameras
Now, let’s get into camera placement—this is where a lot of people trip up.
You can buy the best cameras on the market, but if you don’t place them correctly, they won’t do you much good.
One common mistake is mounting cameras at the wrong height.
I’ve seen people install cameras way up high, thinking the higher the better, but that’s not always the case.
If your camera’s too high, you’ll end up with a nice view of the tops of people’s heads instead of their faces.
On the flip side, putting cameras too low can make them easy targets for tampering.
The sweet spot is around 8 to 10 feet — high enough to stay out of reach, but still able to capture details like facial features.
Another issue is blind spots.
You’d be surprised how many people set up cameras and think they’re covered, only to realize later that there are huge gaps in their coverage.
Think about areas like corners or doorways — these are spots intruders can slip through if your camera isn’t positioned right.
A lot of times, a single camera won’t cut it, especially for larger areas like backyards or driveways.
You need to plan out your coverage carefully, making sure there’s no place for someone to sneak by unnoticed.
Then there’s the problem of direct sunlight.
Trust me, this can be a real pain if you’re not paying attention to how light moves around your house.
Cameras facing the sun might give you a whole lot of glare or overly bright footage, making it hard to see what’s actually happening.
Instead, try to position your cameras so they’re in the shade or angled away from direct sunlight.
If that’s not possible, consider cameras with wide dynamic range (WDR), which helps balance out lighting issues.
Finally, let’s talk about what I call the “obvious but often missed” mistake: not covering key entrances.
You’d think this would be a no-brainer, but so many people forget to focus on their front door, back door, and windows—the exact places where most break-ins happen.
If you don’t have cameras pointed at these high-traffic areas, your system isn’t doing much to keep you safe.
Cover all entry points, and don’t forget to think about less obvious spots, like driveways or side gates.
Proper camera placement can take a little time and thought, but it makes all the difference in actually catching useful footage.
Remember, you’re trying to make sure there’s nowhere for an intruder to hide, and the clearer the view, the better.
False Alarms
Let’s talk about false alarms — the bane of every home security system.
Nothing’s more frustrating than getting a notification in the middle of the night, thinking there’s an intruder, only to find out it was just a gust of wind or your cat knocking something over.
It’s not only annoying, but it can also make you start ignoring alerts, which defeats the whole purpose of having a security system in the first place.
One of the biggest culprits for false alarms is poor sensor placement.
I’ve seen motion detectors installed right next to heating vents, and guess what?
Every time the heat kicks on, the air movement sets off the sensor.
Curtains blowing in the breeze, ceiling fans, or even plants moving can do the same thing.
It’s really important to think about where you’re placing these sensors.
Ideally, you want them aimed away from things that can move or change unexpectedly.
If you have pets, place them at a height where they won’t be triggered by a dog or a wandering cat.
This brings me to non-smart sensors.
A lot of older systems don’t have the ability to adjust their sensitivity, so they’ll go off for the smallest movement.
If you have pets or live in an area where trees are constantly swaying, this can cause endless false alarms.
Upgrading to smart sensors that allow you to adjust the sensitivity or set specific detection zones is a game changer.
Some sensors even have pet immunity features, meaning they can tell the difference between a human and a 20-pound dog, so your furry friend won’t be setting off alarms every time they move around the house.
Then there’s environmental interference, which mostly affects outdoor security systems.
I can’t tell you how many times I’ve seen alarms go off because of a windy day or a bit of rain.
Outdoor sensors that aren’t weatherproof or are too sensitive to small movements (like leaves blowing across the yard) can end up causing way more false alarms than actual alerts.
You need equipment that’s built to handle the outdoors— weatherproof sensors and cameras with settings that let you dial back the sensitivity when needed.
The key to reducing false alarms is balancing sensitivity with accuracy. You want your system to detect real threats but not go off every time a tree branch moves.
Take the time to tweak settings, place sensors properly, and consider upgrading to smarter tech if false alarms are driving you crazy.
The fewer false alarms you get, the more confident you can be that when your system goes off, it’s something you should actually pay attention to.
Single Solutions
A lot of people make the mistake of thinking that just having cameras is enough to secure their home.
I get it — cameras are the most visible part of any security setup, and they do provide a sense of security.
But relying only on cameras can give you a false sense of safety.
The truth is, cameras alone aren’t always a strong enough deterrent, and they don’t prevent break-ins on their own.
Think of cameras as just one piece of the puzzle.
Here’s the thing—cameras can’t physically stop anyone.
They can record footage of someone breaking in, but by the time you review that footage, it might be too late.
That’s why it’s so important to combine your cameras with other security measures, like smart locks, window sensors, and a good alarm system.
Alarms can scare off intruders the second they trip a sensor, and smart locks make it harder for them to get inside in the first place.
When you rely only on cameras, you’re missing out on the extra layers of protection that can actually prevent a break-in from happening.
Another big problem I’ve seen is not using enough cameras or sensors.
People often try to cut corners by only installing one or two cameras, thinking that’s enough to cover their whole house.
But, that can leave major blind spots. If you have a large yard, a multi-story home, or a big driveway, one or two cameras won’t be enough to capture everything.
You need to think about full coverage—inside and out.
That might mean adding more cameras or using additional motion sensors in places where cameras don’t have a clear view.
A well-placed sensor or two can catch movement in those hidden areas where a camera might miss it.
And don’t forget about the remote areas of your property—this is where a lot of people drop the ball.
Places like detached garages, sheds, or backyards are prime targets for intruders, yet they’re often ignored in security setups.
A lot of people think their garage or shed isn’t important enough to monitor, but thieves know these areas are usually less protected.
If you have valuable equipment, tools, or even just an extra entry point to your house, these spots need attention.
A camera or sensor covering these areas can be a huge deterrent.
In short, you need a multi-layered approach to security.
Cameras are great, but they shouldn’t be your only line of defense.
Pair them with smart locks, alarms, and sensors for a more comprehensive system, and make sure you’re covering all the vulnerable spots around your property — not just the obvious ones.
Poor Installation Techniques
Installation — this is where things can really go wrong if you’re not careful.
Even if you’ve bought top-notch equipment and planned everything out, poor installation can sabotage your whole system. I’ve seen a lot of mistakes in this area, especially with wired systems and DIY setups.
The good news? These are pretty easy to avoid if you know what to look out for.
First off, let’s talk about incorrect wiring.
If you’re going with a wired system, you need to pay attention to how everything is connected.
Sloppy wiring can lead to unreliable performance — think cameras losing power or sensors going offline at the worst possible moments.
Not to mention, exposed or loose wires are just an invitation for tampering.
You don’t want an intruder to be able to cut a wire and disable your whole system, right?
Make sure the wiring is properly secured, hidden, and ideally, tamper-resistant. If you’re not comfortable doing this yourself, it’s worth hiring a pro.
Next up is the classic DIY issue: skipping professional installation.
Now, I’m all for DIY projects, but when it comes to home security, sometimes it’s better to leave it to the experts — especially for more complex setups.
I’ve seen DIY installations where cameras are aimed at completely the wrong angle or sensors are missing key areas.
These kinds of mistakes can leave you with gaps in your coverage or equipment that doesn’t work as expected.
Even with DIY, it’s crucial to follow instructions carefully and test everything as you go.
If you’re not 100% sure you’ve got everything dialed in, don’t hesitate to call in a professional to give it a once-over.
I wrote a whole blog post regarding the difference between professional installation and DIY options.
Lastly, let’s talk about secure mounting.
This might sound basic, but you’d be surprised how many people don’t mount their cameras or sensors securely.
If they’re not properly fastened, intruders can easily knock them off, reposition them, or tamper with them.
And if a camera gets bumped or blown by the wind, it could end up pointing in the wrong direction.
For outdoor setups especially, you need to make sure everything is mounted with weather-resistant hardware and can withstand things like wind, rain, or even someone trying to mess with it.
Double-check that your cameras and sensors are firmly secured to walls or ceilings and that you’re using the right brackets for the job.
Bottom line: Proper installation is just as important as picking the right equipment.
Whether you’re going the DIY route or hiring a professional, make sure your wiring is solid, your devices are mounted securely, and everything is positioned to cover the right areas.
A little extra effort during installation can save you a ton of hassle (and potential break-ins) down the road.
No Backups For Power and Internet Outages
Let’s talk about something that a lot of people forget until it’s too late—power and internet outages.
Your security system is only as good as its ability to stay operational, and if you’re not planning for these outages, you could be leaving your home wide open when you’re most vulnerable.
First, let’s get into the issue of no backup power.
I’ve seen it happen: a storm hits, the power goes out, and suddenly your whole security system is dead in the water.
No cameras, no sensors, no alarms—nothing. If an intruder decides to take advantage of that blackout, you’re in trouble.
That’s why having a battery backup is so important.
Many systems come with a built-in backup battery, but not all do, and some homeowners don’t even realize it’s an option.
The best systems will automatically switch to battery power the second the electricity goes out, so you won’t even notice the difference.
And if you’re using wireless cameras or sensors, keep an eye on those batteries, too. You want them fully charged and ready to go in case of an outage.
Now, onto the internet connection.
These days, a lot of security systems rely on Wi-Fi to send you alerts, stream footage, or notify a monitoring service.
That’s all well and good — until your internet goes down.
Whether it’s from a power outage or just a random service disruption, if your system doesn’t have a redundant internet connection, it can’t communicate when it matters most.
This is where having a cellular backup comes in handy.
Systems that switch to a cellular network when the Wi-Fi fails keep you connected to your cameras, alerts, and alarms, even if your internet service is out.
It’s a bit of extra insurance that makes sure your system stays functional, no matter what’s happening with your router.
In some cases, people also forget about offline functionality.
Not every part of your system needs to be dependent on Wi-Fi or electricity to work.
For example, a local storage option like a memory card in your cameras means that even if your internet is down, you’ll still have recorded footage.
When power or connectivity returns, you can review what was captured. It’s another safety net in case things go sideways.
So, here’s the takeaway: plan for the worst.
Make sure your system has a battery backup, and seriously consider a cellular backup or at least some kind of redundant connection.
Because when the power goes out or the internet drops, you don’t want to be sitting there, hoping your security system holds up.
With the right precautions, you’ll have peace of mind knowing your system is ready for anything—even a total blackout.
Ignoring Cybersecurity
These days, most security systems are smart systems, meaning they’re connected to your home network or the internet.
And while that makes things super convenient — you can check your cameras from your phone, get alerts wherever you are — it also opens the door to some serious vulnerabilities if you’re not careful.
One of the easiest ways hackers can get into your system is through weak passwords.
You’d be amazed how many people leave their default passwords in place or use something super easy to guess, like “1234” or “password”.
This meme is FTW 🙂

Think of your security system like the front door to your home.
Would you leave that unlocked? Of course not. But a weak password is basically doing just that.
Always, and I mean always, set a strong, unique password for your system and any related apps.
A good rule of thumb is to use a combination of upper and lowercase letters, numbers, and symbols.
And if you can, enable two-factor authentication (2FA) for an added layer of security.
Then there’s encryption, which is another critical factor in protecting your system from cyber threats.
Not all smart security devices come with strong encryption, especially the cheaper models.
Without encryption, hackers can potentially intercept your footage or tamper with your system remotely.
Always make sure that your cameras, sensors, and control panel are using at least AES 128-bit encryption, though AES 256-bit is even better.
This ensures that the data being sent over your network is secure and much harder for someone to hijack.
Another thing that a lot of people overlook is firmware updates.
I get it — it’s easy to forget.
But manufacturers are constantly rolling out updates for a reason, and it’s usually to patch up security vulnerabilities or add new features.
If you’re not keeping your system’s firmware up to date, you’re leaving the door open for hackers to exploit older weaknesses.
Most smart systems will give you notifications when an update is available, but some people just ignore them.
Don’t be one of those people!
Make it a habit to check for updates regularly and apply them as soon as possible.
In some cases, it’s a good idea to take things a step further and put your security system on a separate network.
If you’ve got a smart home setup with a bunch of devices like smart TVs, speakers, and thermostats, consider creating a dedicated network just for your security system.
This way, even if one of your other devices gets compromised, your security system will be on its own protected network, keeping it safer from any potential breaches.
Don’t overlook cybersecurity.
Your cameras, sensors, and alarms are only part of the equation.
If your system is vulnerable to hackers, it doesn’t matter how good your hardware is.
Secure it with strong passwords, make sure encryption is in place, and stay on top of those updates.
It’s easy to let this stuff slide, but trust me, a little effort here can save you a ton of headaches later.
Poor Maintenance and Testing
One of the easiest ways to undermine your home security system is by neglecting maintenance and testing.
I can’t stress this enough—once everything is installed and working, your job isn’t done.
Like any other system, it needs regular check-ups to make sure it’s functioning properly when you need it most.
Let’s start with the obvious: not testing alarms regularly.
You’d be surprised how often people forget this step.
It’s easy to assume that if you haven’t heard anything, everything’s fine, right?
But alarms, sensors, and cameras can fail without you noticing.
Maybe a sensor got knocked out of alignment, or maybe a camera’s firmware glitched and it stopped recording.
The only way to know for sure is to test your system every so often.
This can be as simple as walking through the house and triggering your motion detectors, checking camera feeds, or doing a full system test through your app.
If your security company offers remote monitoring, they might have a testing feature that makes this process even easier.
Then there’s the issue of battery-powered cameras and sensors.
I can’t tell you how many times I’ve seen systems fail simply because someone forgot to change the batteries.
If your cameras or sensors are running on batteries, you need to check those regularly. Most smart systems will give you a low-battery alert, but don’t rely solely on that.
Make it part of your routine to manually check the battery levels and swap them out before they die on you.
You can also look into solar-powered cameras, which can save you the hassle of battery changes, but even those need maintenance every now and then to make sure they’re getting enough sunlight.
And don’t forget about weather damage — this is a big one for outdoor security equipment.
Cameras, sensors, and alarms that are exposed to the elements need to be weatherproof and durable, but even the best equipment can wear down over time.
Harsh sunlight, rain, snow, or even dust buildup can affect the performance of outdoor cameras.
Make it a habit to check on your outdoor devices a few times a year.
Clean the lenses, check for rust or damage, and make sure everything is still securely mounted.
If you live in an area with extreme weather, this becomes even more important.
Some systems are rated for certain weather conditions, but that doesn’t mean they’re invincible.
The key here is regular maintenance and testing.
It might feel like overkill, but trust me, it’s way better to catch a problem during a routine check than to discover it when something goes wrong.
Your security system is only as good as its weakest part, and if something isn’t working—whether it’s a dead battery, a misaligned sensor, or a weather-damaged camera—you’re leaving a gap in your protection.
When it comes down to it, setting up a reliable home security system isn’t just about buying the best equipment.
It’s about getting all the little details right: picking the right gear, placing it properly, installing it securely, and keeping everything running smoothly with regular checks and updates.
If you take care of these things — everything from choosing high-quality cameras to testing your alarms — you’ll have a system that truly keeps you, your family, and your home safe.
