A security camera system is only as valuable as its integrity. If your cameras are streaming footage to someone who shouldn't have access — a hacker halfway around the world, or a disgruntled former employee who still knows the admin password — your system isn't protecting you. It's exposing you. IP camera cybersecurity isn't a niche concern for tech companies; it's a real vulnerability for NYC co-op boards, retail store owners, building managers, and anyone running a networked camera system. The good news is that most camera hacks are entirely preventable with the right configuration and habits. Here's how to protect your security camera network before a breach happens.
Why IP Cameras Are Vulnerable in the First Place
IP cameras are small computers connected to your network. Like any networked device, they run firmware, accept login credentials, and communicate over the internet — which means they can be compromised if they're improperly configured or left with factory defaults in place. Unlike a laptop, most cameras run quietly in the background without anyone thinking to update or audit them.
Search engines like Shodan actively index publicly accessible devices, including IP cameras with default passwords or open ports. A camera installed in a Midtown Manhattan office building or a Crown Heights co-op lobby could be visible to anyone running a basic scan — not because the system was installed wrong per se, but because no one took the extra steps to lock it down after installation.
Budget-brand cameras, in particular, carry higher risk. Many ship with weak default credentials, infrequent firmware updates, and less robust encryption. This doesn't mean you need to spend a fortune, but it does mean that choosing a reputable brand and configuring it correctly matters enormously.
Change Default Credentials — Every Single Time
This sounds obvious, but it remains the most common failure point in IP camera security. Manufacturers ship cameras and NVRs with default usernames and passwords — often something like admin/admin or admin/12345. These defaults are publicly documented and widely known. If you never change them, your system is effectively unlocked.
Every camera, every NVR, and every recorder on your network needs a unique, strong password set during installation. That means at least 12 characters with a mix of letters, numbers, and symbols — not the building address, not the company name. Whoever installs your system should document these credentials securely and provide them to you directly. If a security installer hands you a system without walking you through credential management, that's a red flag worth noting before you sign off on the job.
Also disable any accounts you don't use. Many NVR platforms include guest or operator accounts that are enabled by default. If you don't need them, turn them off.
Segment Your Camera Network from Everything Else
One of the most effective IP camera cybersecurity best practices is network segmentation — keeping your camera system on its own isolated VLAN (Virtual Local Area Network), separate from your business computers, point-of-sale systems, or tenant WiFi. This way, even if a camera is compromised, an attacker can't use it as a foothold to reach your other systems.
In a dense urban environment like New York City, this matters more than most people realize. A single commercial building might house a restaurant, a medical office, and a law firm — all sharing infrastructure managed by a building super who's juggling a dozen other priorities. Without proper network segmentation, a compromised camera in the restaurant's storage room could theoretically sit on the same network as the law firm's workstations. Proper structured cabling and network architecture from the start makes segmentation far easier to implement and maintain.
NYC Pro Tip: In mixed-use buildings or multi-tenant properties, always request a dedicated network switch or VLAN for your camera system — don't let cameras share a switch with general office or residential traffic. If your building's managing agent pushes back on this, it's worth having your low-voltage contractor explain the liability exposure directly. A compromised camera system that exposes tenant data is a lawsuit waiting to happen.
Keep Firmware Updated and Audit Your System Regularly
Firmware updates for IP cameras and NVRs frequently include security patches that close known vulnerabilities. Skipping updates — or never checking for them — leaves those vulnerabilities open indefinitely. Manufacturers like Axis, Hanwha, and Hikvision regularly release firmware updates; the question is whether anyone on your end is actually applying them.
Set a reminder to check for firmware updates at least quarterly. Most NVR interfaces have a built-in update check. If your system is managed by a security contractor, confirm that firmware maintenance is part of your service agreement — not an afterthought.
Beyond firmware, audit your system periodically. Review which user accounts have access, check whether any remote access ports are still open and necessary, and look at your system logs for unusual login attempts or access from unfamiliar IP addresses. This kind of routine hygiene catches problems before they become incidents. If you're uncertain how to interpret your system logs, your installer should be able to walk you through what to look for.
Secure Remote Access the Right Way
Remote access to your camera system — being able to check live footage from your phone while you're off-site — is genuinely useful. But how that remote access is configured is where many systems get exposed. Avoid leaving ports directly open to the internet unless absolutely necessary, and never use unsecured HTTP access for remote viewing.
The safest approach is to use a VPN (Virtual Private Network) to access your camera network remotely rather than exposing the NVR's web interface directly to the internet. Many commercial-grade NVR platforms support this natively or integrate with cloud relay services that don't require open inbound ports. If your system uses a mobile app for remote viewing, verify that it communicates over encrypted connections and requires multi-factor authentication where available.
If you're deciding between local NVR storage and cloud-based recording, cybersecurity implications are worth factoring into that decision. A locally stored system with no internet exposure is inherently more isolated, while a cloud system trades some of that isolation for convenience. For a deeper look at how those trade-offs play out, this comparison of cloud storage vs. local NVR/DVR breaks down the key considerations.
Work with a Qualified Installer Who Prioritizes Cybersecurity
The physical installation of your camera system and the network configuration that goes with it are inseparable. A camera mounted in exactly the right location but connected to an unsecured network is only doing half the job. When you're evaluating who to hire, ask specifically how they handle network configuration, default credential changes, firmware practices, and remote access setup. If the installer looks confused by the question, that tells you something important.
For NYC properties, this is particularly relevant because many camera installations happen in buildings with existing, often aging network infrastructure — pre-war brownstones running decades-old wiring, commercial lofts in Bushwick with improvised IT setups, or Midtown office buildings where the cabling was last touched during a renovation in 2005. A qualified low-voltage contractor evaluates the full picture and recommends the right infrastructure alongside the right cameras. Before you hire anyone, it's worth knowing what questions to ask — our guide on how to evaluate a security installer before hiring covers exactly what to look for.
Choosing the right cameras and recorder also matters. Established brands with active firmware support, strong encryption standards, and a track record of patching vulnerabilities will always be a safer long-term investment than no-name hardware that costs less upfront but receives no security updates after the first year. Your security camera system should be specified with both physical performance and cybersecurity in mind from the start.
Protecting your security camera network from hackers isn't complicated, but it does require deliberate configuration, ongoing maintenance, and working with an installer who takes network security seriously — not just camera placement. Seneca Security installs and configures IP camera systems with cybersecurity built into the process, from network segmentation and credential management to firmware practices and secure remote access. We offer free quotes and serve property owners and businesses throughout NYC and the tri-state area.
