Are Your Security Cameras a Cyber Risk? Protecting Michigan Businesses from Hacked Cameras & Access Control

Here's a question most Michigan business owners never think to ask: could your own security cameras be a way into your business? It sounds backwards — the cameras are supposed to protect you. But every modern commercial security camera, NVR, card reader, and door controller is really a small internet-connected computer sitting on your network. And when those devices are installed carelessly, they become one of the easiest targets on your property. New industry research shows a growing cybersecurity gap in physical security and access control systems — and attackers know it.
Why security cameras and access control are a cyber target
A camera system is attractive to attackers for three reasons. First, these devices are often installed once and then forgotten — default passwords are never changed and firmware is never updated. Second, they're almost always connected to the same network as your business computers, point-of-sale, and files, so a weak camera becomes a door into everything. Third, a compromised camera gives an attacker exactly what you were trying to prevent: a live view of your property, your people, and your operations.
The most common weaknesses we find on existing Michigan commercial systems are depressingly simple: the manufacturer's default password still in place, firmware that hasn't been patched in years, remote-viewing ports left wide open to the internet, and a "flat" network where the cameras can talk directly to the accounting PC. None of these require a sophisticated hacker to exploit.
The Hikvision and Dahua problem
Cybersecurity is a big part of why Hikvision and Dahua cameras are banned from U.S. federal systems under the NDAA, and why the FCC has expanded restrictions on them. Many Michigan businesses still have this hardware on the wall without realizing it. If that's you, it's worth reading our full guide to the Hikvision ban and what Michigan businesses should do — and planning a move to NDAA-compliant, security-hardened cameras.
How to protect your commercial camera and access systems
The good news: securing a commercial security system is well-understood, and a professional integrator builds these protections in from day one. The core steps:
- Change every default password — on cameras, recorders, controllers, and admin accounts, using strong unique credentials.
- Keep firmware updated — manufacturers patch security holes constantly; outdated firmware is the #1 easy target.
- Segment the network — put cameras and access control on their own isolated VLAN so a compromised device can't reach your business data.
- Lock down remote access — use encrypted, properly configured remote viewing instead of exposed ports, and disable features you don't use.
- Use hardened, NDAA-compliant equipment — cameras like the Hanwha Vision Wisenet series are built with cybersecurity in mind.
- Manage credentials and offboarding — revoke access the moment an employee or contractor leaves; lingering credentials are a top risk.
Cyber-physical convergence: why IT and security now overlap
The line between physical security and IT security has disappeared. Your cameras and door controllers live on the network, so they're an IT concern — and your network's safety now depends partly on how your physical security was installed. The businesses that handle this well treat their security system as part of their overall cybersecurity posture, with hardened devices, segmented networks, and a plan for who's responsible when something looks wrong. This is exactly why working with a commercial integrator who understands networks matters.
What Michigan Security Systems does differently
We're a commercial-only security integrator serving Michigan, Ohio, and Indiana since 2000, and we treat your cameras, access control, and network infrastructure as one hardened system — not a box on a wall. Every install is done by our own licensed Michigan technicians, with changed passwords, updated firmware, proper network segmentation, and secure remote access configured from the start. We also assess and harden existing systems across Macomb, Oakland, and Wayne counties. If you're not sure whether your current cameras are a liability, book a free on-site assessment and we'll give you a straight answer.
Can commercial security cameras really be hacked? Yes. Any camera, NVR, access controller, or card reader on your network is an internet-connected computer, and weak or default passwords, outdated firmware, and flat networks make them a target. Attackers use compromised cameras to watch your property, pivot into your business network, or rope devices into botnets. Hardening these devices like IT assets is now a core part of a professional commercial install. Are Hikvision and Dahua cameras a cybersecurity risk? Hikvision and Dahua cameras are banned from U.S. federal use under the NDAA over security and surveillance concerns, and many Michigan businesses are replacing them for both compliance and cyber-risk reasons. We cover this fully in our Hikvision ban guide. For most commercial clients we recommend NDAA-compliant, security-hardened cameras instead. How do I protect my business security cameras from being hacked? The essentials: change every default password, keep camera and NVR firmware updated, put cameras and access control on a separate (segmented) network from your business data, disable unused ports and remote features, use encrypted connections, and work with an integrator who hardens devices at install and monitors them afterward. What is network segmentation for security cameras? Network segmentation means putting your cameras, NVRs, and access control on their own isolated network (often a separate VLAN) so that even if a camera is compromised, an attacker can't jump to your business computers, point-of-sale, or servers. It's one of the most effective and under-used protections for commercial systems. Do you secure access control systems too, not just cameras? Yes. Card readers, door controllers, and cloud access platforms are networked endpoints with the same risks. We install access control with hardened controllers, encrypted credentials, strong admin practices, and proper network isolation, and we help you retire lingering contractor and ex-employee access that creates real exposure. Can you review or upgrade our existing camera system for cyber risk? Absolutely. We assess existing commercial camera and access systems across Michigan for default passwords, outdated firmware, unsafe remote access, and flat-network exposure, then harden or upgrade what's needed.
