So had a friend ask if they should get rid of some of the older cameras that I told him to hold on to and thought I would share what I would do if you also have some old IP cameras that no longer get updates..

When it comes to older IP cameras, there’s no denying that they can be a security risk. Many of these devices lack modern firmware updates, encryption standards, or other protections necessary to fend off today’s cybersecurity threats. However, there are ways to mitigate these risks effectively, and one of the best methods is pairing these older cameras with a PoE NVR where they can operate behind the NVR’s internal network.

Understanding the Security Risks
Older IP cameras are notorious for outdated firmware, hardcoded credentials, and vulnerabilities that can expose them to hackers. These vulnerabilities can allow attackers to:
Gain unauthorized access to your network.
View live or recorded footage.
Use your camera as part of a botnet in distributed denial-of-service (DDoS) attacks.

Why Use a PoE NVR?

A PoE (Power over Ethernet) NVR (Network Video Recorder) combines video recording and camera management in a centralized system. Unlike standalone IP cameras that are directly exposed to the network, cameras connected to an NVR can leverage the following benefits:
Isolation from the Internet
Cameras connected to the NVR's internal PoE switch are often isolated from the external network. This setup ensures that the cameras cannot directly communicate with the broader internet, effectively shielding them from remote attacks.
Centralized Management
The NVR manages all camera connections, reducing the need to expose individual cameras’ IPs or ports. This minimizes the attack surface of the system.
Controlled Access
Remote access to the cameras and recordings is facilitated through the NVR, which can have up-to-date security protocols, such as encryption and multi-factor authentication, to protect against unauthorized access.
Streamlined Updates
While older cameras may no longer receive firmware updates, modern NVRs often do. Keeping the NVR’s firmware current ensures that the system has the latest security patches to protect its gateway to the network.
Power and Connectivity Efficiency
PoE simplifies setup by combining power and data into one cable, reducing the complexity of managing individual camera connections.

Best Practices for Secure Deployment
If you plan to use older IP cameras, follow these guidelines to enhance security:
Segment the Network: Place the NVR and cameras on a separate VLAN to further isolate them from other devices.
Disable Unnecessary Features: Turn off any unused protocols or services on the cameras.
Change Default Credentials: Use strong, unique passwords for accessing the NVR.
Use a Firewall: Restrict traffic to and from the NVR using firewall rules.
Monitor Traffic: Employ tools to monitor network activity for unusual behavior.

Conclusion

While older IP cameras may not have the robust security features of their modern counterparts, leveraging a PoE NVR can significantly reduce their exposure to potential threats. By isolating these cameras behind the NVR’s internal network and following best practices, you can extend their usability while maintaining a secure surveillance setup. This approach is not just cost-effective but also ensures peace of mind in managing legacy systems.

Just my 2 cents. Figured I would write something and share with others that might have some older quality IP cameras and not sure what to do with them.. I mean yeah loads of people on here already use Vlans but others that just looking for help on what they can do may not know a POE NVR can be best case for their old Cameras..
