Think your cameras have everything covered? Most Delaware County homeowners don't realize what their system is missing until it's too late.
A crime happens in Delaware County roughly every 40 minutes. That’s the reality for a county that borders Philadelphia and includes communities ranging from Chester to Upper Darby to Ridley Park. Most homeowners respond the right way: they go buy cameras. The problem is that buying cameras and having a working security camera system are two very different things. The gap between those two — the placement decisions, the network setup, the storage choices, the integrations — is where most home security actually breaks down. Here’s what that gap looks like, and how to close it.
The most common mistake isn’t a bad camera — it’s a missing plan. Most people buy a camera for the front door, maybe one for the backyard, and call it done. What they don’t do is walk the full perimeter of their property and ask: where would someone actually try to get in, and would any of my cameras catch it?
Entry point coverage sounds obvious until you realize how many homes have a side gate, a detached garage, a basement window, or a back door that never makes it onto anyone’s camera map. In Delaware County’s older housing stock — the row homes in Folsom, the mid-century colonials in Glenolden, the split-levels in Norwood — there are often more entry points than a homeowner mentally accounts for. A professional walkthrough catches the ones you’d never think to look for.
Camera placement is more technical than it looks. The general standard is 8 to 10 feet off the ground — high enough that a camera can’t be grabbed or covered, low enough that it captures a usable image of a person’s face rather than just the top of their head. Get that wrong in either direction and your footage becomes nearly useless for identification purposes.
Angle matters just as much as height. Cameras pointed directly into a light source — a streetlamp, a west-facing wall that catches afternoon sun, a bright porch fixture — will wash out during exactly the hours you need them most. It’s a mistake that’s easy to miss when you’re testing the system on a cloudy Tuesday afternoon, and only obvious when you’re trying to pull footage after an incident and realize the image is overexposed.
Night vision is the other piece that almost always gets undertested. Cameras look sharp during daylight. At night, especially in the tree-lined residential streets common across Delaware County, infrared performance varies dramatically between camera models and mounting positions. A camera that “works” during the day may produce footage at 2am that’s too grainy to be useful. Testing in actual darkness — not just checking that the night vision mode activates — is something most DIY installs never do.
There’s also the question of field of view. Wide-angle lenses cover more ground but distort the edges of the image. Narrower lenses give you better detail over a smaller area. Matching the right lens to the right location — a wide driveway versus a narrow side passage, for example — is a judgment call that comes from experience, not from the box the camera came in.
Wireless cameras are popular because they’re easy to install. They’re also easy to get wrong in ways that don’t show up until something goes wrong. The most common issue is signal. A camera mounted on the back corner of a house, or above the garage, or at the far end of a long driveway may be sitting right at the edge of your router’s range. The app shows it as connected. But under real conditions — during a storm, when network traffic is high, when a neighbor’s signal interferes — it drops out. And those dropouts don’t always get logged.
The more serious issue is network security. A camera connected to your home Wi-Fi with its factory-default password is a liability. Security researchers have demonstrated repeatedly that improperly secured cameras can be accessed remotely — not by sophisticated hackers, but by anyone running basic scanning tools. The fix is straightforward: cameras should be placed on a separate network segment from your primary devices, passwords should be changed from the defaults, and firmware should be kept current. Most DIY installations skip all three steps.
This matters more in Delaware County than people realize. The county’s proximity to Philadelphia means it sees the kind of opportunistic property crime — package theft, car break-ins, residential burglaries — where a compromised camera isn’t just a privacy problem, it’s a security one. If someone can see your camera feed, they can also see when you’re not home. A properly installed system closes that door. An improperly secured one opens a new one.
Wired systems using Power over Ethernet — PoE — avoid the signal reliability problem entirely. They’re harder to install but significantly more dependable, especially for outdoor cameras that need to perform in Delaware County winters when ice and cold can stress wireless connections. The right choice between wired and wireless depends on the home’s layout and your priorities. But it’s a choice that should be made deliberately, not by default.

Once the cameras are placed correctly and the network is secure, the next decision is storage. Where does your footage go, how long does it stay there, and who has access to it? These questions matter more than most people expect — and the answers aren’t the same for every household.
Cloud storage is convenient. You can pull footage from anywhere, and it’s protected if someone physically damages or steals a camera. The tradeoffs are ongoing subscription costs and the fact that your footage lives on someone else’s server. Local storage — an NVR or DVR on your home network — keeps your data in your control and eliminates monthly fees, but it can be damaged or stolen in a break-in. A hybrid approach, local primary storage with cloud backup, is often the most practical answer for homeowners who want both reliability and control.
Cameras alone record what happens. They don’t stop it. That’s not a limitation of cameras — it’s just the reality of what they do. The homes that are genuinely well-protected are the ones where the camera system is part of a larger picture: locks that are properly specified for the entry points they’re protecting, an alarm system that responds in real time, and access control that manages who can get in and when.
The problem most homeowners run into is that they’ve assembled these pieces from different sources — a Ring doorbell from Amazon, an alarm from one company, a smart lock from another — and nothing talks to anything else. You end up with three separate apps, no coordinated response when something triggers, and a system that’s more complicated than it needs to be without being more secure.
Integration isn’t just a convenience feature. When a camera detects motion at your back door at 1am and your alarm system knows about it immediately, that’s a meaningfully different outcome than a camera that logs the event while your alarm stays silent. For Delaware County homeowners in communities like Upper Darby or Sharon Hill — areas where the crime statistics are real and not abstract — that difference matters.
We’ve been installing locks, access control, and security systems in Delaware County for five generations. When we do a camera installation, we’re not just mounting hardware — we’re looking at how it connects to everything else in your home’s security setup. That’s a different kind of assessment than what you get from a camera company that only sells cameras.
The honest answer is that a capable homeowner can install a basic camera system. The question is whether the result will actually do what you need it to do — and whether you’ll know the difference if it doesn’t.
Professional installation isn’t about the physical act of mounting a camera. It’s about the decisions that happen before the first screw goes in: which cameras belong where, what resolution and field of view are appropriate for each location, how the system integrates with existing security infrastructure, how storage is configured, and how the network is secured. Those decisions require experience with a lot of different homes and a lot of different outcomes — not just familiarity with the product manual.
There’s also a trust issue that’s specific to this area. Delaware County and the surrounding Philadelphia suburbs have a documented problem with unlicensed contractors posing as local security companies. They show up in unmarked vehicles, can’t tell you who they work for, and often disappear after the job if something goes wrong. We’ve seen it firsthand — there have been cases of companies actively impersonating McCausland Lock Service to homeowners searching online.
We hold Pennsylvania Attorney General license PA 013604. We’ve been operating out of our Prospect Park location since long before most of the companies currently advertising in this market existed. When a technician from our team shows up at your door, you know exactly who we are and who we answer to. That accountability doesn’t come with a kiosk key-cutting service or a national dispatch company routing calls through a call center. It comes from being a real local business with a real address and 140 years of reputation to protect.
The other thing experience changes is what happens after installation. Cameras go offline. Firmware updates break app integrations. Storage fills up. A DIY install means you’re on your own when any of that happens. A professionally installed system from us means you have someone to call — and someone who already knows your setup.
Most security camera mistakes aren’t obvious until you need the footage and it isn’t there — wrong angle, dead Wi-Fi zone, storage that ran out, a blind spot you never knew existed. By then, the moment you needed the system to work has already passed.
The good news is that none of this is complicated when it’s planned correctly from the start. Proper placement, a secure network, the right storage setup, and integration with your existing locks and alarm system — these aren’t luxury add-ons. They’re what makes a camera system actually function as security rather than just hardware on a wall.
If you’re in Delaware County and you’re not sure whether your current setup is doing its job — or you’re starting from scratch and want it done right — reach out to us at McCausland Lock Service. We’ll walk through your property, tell you exactly what you have and what you’re missing, and give you a straight answer about what it takes to fix it.
