Installing security cameras yourself: what works, what fails, and when to hire it out

A couple of plug-in cameras are a reasonable weekend project. Covering a whole house or a storefront is a different job. Here is where the line falls and how to get placement right either way.

Yes for a few cameras, usually no for a whole property

You can install a video doorbell or one or two plug-in or battery Wi-Fi cameras yourself, and for a renter or a small apartment that is often enough. Once you want reliable coverage of every approach to a house, cameras on a second story, footage that does not depend on your Wi-Fi, or video tied to a monitored alarm, a professional install with wired cameras usually works better and lasts longer. The deciding factors are how many cameras, where they go, and what you expect them to do when something happens.

Cameras are our specialty at Foresight Security, and we install them on houses and storefronts every week. Plenty of people call us after a DIY attempt, not because they did anything wrong, but because the cameras did not perform the way the box suggested. This guide explains why, and how to decide before you spend the money.

What a DIY setup does well

Consumer Wi-Fi cameras are easy to buy and quick to set up. For a renter who cannot run cable, a parent who wants to check on a nanny, or someone who just wants to see who is at the door, they solve a real problem in an afternoon. A video doorbell catches package deliveries and visitors at the front door. An indoor camera in the main living area shows you whether the dog got into the trash.

If that is the whole goal, DIY is a reasonable choice. Pick a camera brand with a well-reviewed app, put the cameras where your Wi-Fi is strong, and set motion alerts so you are not notified every time a car drives by.

Many Dallas homeowners we meet started this way, and some of those cameras still earn their keep. A doorbell you like can stay where it is while wired cameras cover the rest of the property.

Where DIY cameras run into trouble

The problems start at the edges of the house. Wi-Fi is usually strongest in the middle of a home and weakest at exterior corners, which is exactly where outdoor cameras need to be. Brick, stone and stucco walls weaken the signal further. A camera on a weak connection drops frames, records blurry video or goes offline, and you often find out only when you go looking for a clip that is not there.

Battery cameras add another failure point. Batteries need charging, and they drain faster in heavy use and in temperature extremes. A camera with a dead battery records nothing. Wired cameras avoid both issues: the cameras we install are hard-wired, so image quality does not depend on your Wi-Fi speed and nothing needs to be recharged.

There is also the question of what you see when an alert comes in. A consumer camera that sends a motion notification at 2 a.m. leaves you deciding alone, half awake, whether to call 911. That is fine for a package on the porch. It is a lot to ask when someone is at the back door.

  • Weak Wi-Fi at exterior corners, garages and back fences
  • Batteries that die without anyone noticing
  • Video quality that drops when the network is busy
  • Separate apps for each brand, with separate logins
  • No connection to a monitoring center when something happens

The physical part of the job

Mounting a camera on a first-floor wall near an outlet is simple. Mounting six cameras on the eaves of a two-story house, with cable run through the attic to a recorder inside, is real work. One of our customers wrote in a review that the job on his house was not easy because it was two stories and our team had to run cables through the attic. That is typical.

Attic work means moving on joists, around insulation and wiring, and in North Texas summers the attic gets very hot. Exterior work means ladders at height. Drilling through siding or brick means sealing every penetration so water does not follow the cable inside. None of this is exotic for a technician, but it is where DIY projects stall, get left half finished, or get done in a way that causes a leak later.

Placement matters more than the camera

Whether you install cameras yourself or hire someone, placement decides whether the footage is useful. Start with the approaches burglars actually use: the back door, side gates, the garage, and windows hidden from the street. Then cover the front door and driveway. Every camera should have a clear job, such as identifying a face at the back door or catching a car entering the driveway.

Mount cameras high enough that they cannot be easily knocked down, but not so high that they only capture the tops of heads. Avoid pointing a camera straight into the rising or setting sun. Watch for night glare from a nearby light or a white soffit. Be considerate about neighbors' windows and yards. And if the system records to a box inside the house, put that recorder somewhere a burglar is unlikely to find and carry off.

  • Back door and back yard
  • Side gates and the side yard
  • Garage doors and the driveway
  • Front door and front walk
  • Any window or door hidden from the street

Settle storage and access before you buy anything

The camera is only half the system. The other half is where the video goes and who can see it. Some cameras record to a memory card inside the camera, some to a recorder in the house, and some to cloud storage that usually carries a monthly fee. Decide how many days of footage you want to keep and whether you are comfortable with a camera that can be stolen along with its own recording.

Then think about access. Who in the household gets the app? Does a house sitter or a dog walker need temporary access? Can you share a single clip with police without handing over your login? Mixed brands make this harder, because each camera has its own app and its own account. One platform for cameras, alarm and locks keeps it manageable, and it means one place to check when something happens.

  • Days of footage you want to keep
  • On-camera, in-house recorder or cloud storage
  • Monthly fees for cloud video
  • Who gets app access, and how to remove it
  • How you will export a clip for police or insurance

When to stop and call someone

Stop if the plan involves working on a ladder above a first-floor roofline, crawling through an attic in summer, cutting into exterior walls, or running new power. Stop if you need more than three or four cameras to cover the property, because at that point the network and storage design start to matter. Stop if the cameras are for a business, where you need to cover registers, back rooms and rear exits and may need to show footage to police or an insurer.

Also call if you want the cameras to work with a monitored alarm. A DIY camera can send you a notification, but it cannot dispatch anyone. If you are weighing that difference, our comparison of professional monitoring and self-monitoring covers who responds in each case.

What a professional camera install looks like

When we install cameras, the job starts with a consultation at the property. We walk the outside with you, decide where each camera goes and what it needs to capture, and plan the cable routes. On installation day, our licensed technicians run the cable, mount and aim the cameras, connect the recording, and set up the app on your phone. Before leaving, they show you how to view live video, pull recorded clips and adjust alerts.

Our home camera systems give you HD color video day or night, live viewing from a phone, tablet or computer, and short on-demand video clips from your interior and exterior cameras. Motion detection can send a clip and an immediate alert. When cameras are part of a monitored system, central station operators can view live video and recorded clips when an alarm comes in, which helps them judge what is happening. Cameras can also be viewed on the touchscreen keypad.

What a business needs that a house does not

A storefront or restaurant asks more of cameras. You want the registers, the sales floor, stockrooms, back offices and rear exits covered, and sometimes a pan-tilt-zoom camera on a parking lot. Owners with more than one location want every site in one dashboard. Video analytics can alert on motion after hours, and recorded footage can be searched by time and location when you need to find a specific moment.

These are the setups where DIY consumer cameras fall shortest. If you run a small business, our guide to the security mistakes small businesses make covers camera coverage alongside codes, alerts and access control.

Making the decision

If you want one or two cameras and your Wi-Fi reaches, try DIY. If you want the whole property covered, cameras on a second story, footage that does not depend on Wi-Fi, a business covered properly or cameras tied to monitoring, get a professional quote and compare. Our guide on what drives the cost of a security system explains what goes into that number.

We install camera systems for homes and small businesses across Dallas-Fort Worth. Call or fill out the form, and we will walk the property with you, recommend where cameras should go and why, and give you a written quote. If you go ahead, we install, set up the app and train you before we leave, and we service what we install.

Questions people ask me

Are wired security cameras better than wireless ones?

For a house you plan to stay in, usually yes. Wired cameras do not depend on Wi-Fi signal or batteries, so image quality stays consistent and they keep recording. Wireless cameras are easier to install and make sense for renters or a camera or two in a spot cable cannot reach.

Can I add professional cameras to a DIY doorbell I already have?

Often you can keep using a doorbell you like while adding wired cameras elsewhere, though you may end up with two apps. If you want everything in one app with your alarm, ask the installer which doorbells work with their platform.

Where should the camera recorder go?

Somewhere out of sight and not near the main entry, such as a closet or a cabinet. A recorder sitting next to the TV can be carried off with the footage of the person carrying it. Cloud-hosted video avoids that risk because the footage is stored off-site.

How many cameras does a typical house need?

It depends on the layout, not the square footage. Most houses need coverage of the front door, driveway, back door and side gates at minimum. Walk the outside and count the approaches someone could use without being seen from the street.
