Wire the front door, battery the rest, solar only where it's sunny

Quick answer: Wire the cameras that watch your front door and driveway. Use battery cameras where there's no outlet and you can reach them on a short ladder. Add solar only where the camera gets real, direct sun and you'd rather not climb at all.

Start with the ladder, not the camera

Most people shop by resolution and brand. Then they mount the camera and find out what they actually bought: a job.

A battery camera is a recurring errand. A wired camera is a one-weekend project that you then forget about. A solar camera is a battery camera with a better attitude. Which one you want depends on three things at each spot. How far is the nearest outlet or router? How much goes past the lens every day? And how bad is it if the camera is dead the one night you needed it?

Answer those, and the choice mostly makes itself.

Wired: the camera you stop thinking about

Wired is the right answer for the spots that matter most. Your front door. The driveway. The side gate that everybody uses.

You've got two routes. The simple one is a camera that plugs into an outlet through a weatherproof run. The cleaner one is Power over Ethernet, where a single network cable carries both power and video. Ethernet is good for 328 feet, so most houses can reach every corner. You also get a steadier connection than Wi-Fi gives you.

Now the annoying part. Somebody has to get that cable from the router or an outlet to a spot ten feet up the outside wall. That means a long drill bit, a fish tape, and probably an hour in a hot attic. Budget a full Saturday for the first camera. The second goes faster.

Do it properly:

• Leave a small loop of slack below the camera so rainwater drips off instead of running into the connection.
• Seal the hole through the siding with exterior-grade caulk.
• Staple the cable neatly. Don't leave it dangling off the soffit like a loose shoelace.

If you rent, ask first. A wired install usually means a hole in somebody else's wall, and a battery camera on a removable mount may be the honest answer there.

One more thing. Wired cameras die in a power outage, which is exactly when you'd like them awake. If you've got a recorder or a PoE switch, plug it and your router into a small battery backup. It's cheap insurance for the worst night.

Battery: easy to install, easy to underestimate

A battery camera goes up in ten minutes with a screwdriver. That's the whole appeal, and it's real. For a back corner of the yard, a shed, or a rental, nothing beats it.

But it doesn't record all day. It sleeps until it sees motion, wakes up, records a clip, and goes back to sleep. That wake-up takes a moment. On a front porch, that delay can mean your clip starts with somebody's back as they walk away. For the spot where you most want to see a face, that's a bad trade.

Then there's the drain. Four things empty a battery faster:

• Busy views. A camera pointed at a street gets triggered by every passing car. Use motion zones to cut out the road and shorten the clip length.
• Cold. Batteries lose capacity in low temperatures. Check the camera's spec sheet for its operating range before you mount one in a northern winter.
• Weak Wi-Fi. A camera straining to reach the router burns more power on every upload. Stand where you'll mount it and check the signal on your phone. If it's poor, move the router, add an access point, or pick another spot. The home internet numbers that matter will tell you what to look at.
• Sensitivity cranked to maximum. Every leaf and spider web becomes an alert.

Here's the habit that makes battery cameras livable. Buy a spare battery if the model offers one. Charge it on a shelf. When the camera runs low, swap them in thirty seconds and charge the old one. The camera is never down, and the chore is a two-minute one instead of an afternoon.

My rule: if you'd be upset to miss it, don't put it on battery.

Solar: great in the right place, a letdown in the wrong one

A solar camera is still a battery camera. The panel trickle-charges the battery so you climb the ladder less. That's all it does, and it does it well when conditions cooperate.

They don't always. A panel needs hours of direct sun. A north-facing wall, a spot under the porch roof, or the shady side of a big maple won't give it enough. Winter makes it worse, with short days and snow sitting on the panel. Dust and pollen cut the charge too, so wipe the panel when you wash the windows.

Where it shines is the place that's too far for a cable and too sunny to ignore. A detached garage. A barn. The gate at the end of a long driveway, where running power would mean renting a trench digger. Many solar kits let you mount the panel on its own cable, so the camera can sit in the shade while the panel sits in the light. Use that.

Don't buy solar to avoid thinking about power. Buy it for a specific sunny spot, and check the battery level in the app for the first few weeks. If the number is climbing or holding steady, you've got it right.

What a sensible house looks like

Picture a typical two-story house with a detached shed:

• Front door: wired. It's the spot you most need to be reliable.
• Driveway: wired off the garage, because that's where the outlet is.
• Back patio: battery, on a mount you can reach with a stepladder, with a spare battery on the shelf.
• Shed: solar, mounted where the sun hits it for most of the day.

Four cameras, three power sources, and each one is there for a reason. Compare that to the common version: five battery cameras everywhere because the box said "wire-free," and a dead one at the front door the week a package goes missing.

If you want the bigger picture on gear that earns its keep, smart home kit that earns its place is worth ten minutes before you buy anything else.

Before you drill

A few things people skip.

Point it at your own property. Don't aim a camera at a neighbor's windows or their backyard. If it sees their driveway or their front walk, tell them. Five minutes of conversation over the fence is cheaper than a feud, and most neighbors will be glad you've got eyes on the street.

Lock the account. A camera is only as private as the login behind it. Use a unique password and two-factor sign-in, the same way you would for your bank. The evening it takes is covered in lock down every account you own in one evening.

Check where the video lives. Some cameras store clips on a memory card or a local drive. Others want a monthly subscription for cloud storage. Read the plan before you buy, not after you've mounted four of them.

Make sure your family knows. Your wife and your kids should be able to open the app and find the clip. A camera only you can operate helps nobody when you're traveling for work.

Leave the house better than you found it. Seal the holes. Tuck the cable. Take the packaging to the recycling bin. A good install is one a stranger would walk past without noticing.

Do the front door first, wired, on a Saturday morning. Everything else is easier once the important one is done right.
