Mandatory actions to be taken towards cybersecurity
1. Change Passwords and Use Strong Passwords:
The number one reason systems get “hacked” is due to having weak or default passwords. It is
recommended to change default passwords immediately and choose a strong password
whenever possible. A strong password should be made up of at least 6 numbers.
2. Update Firmware
As is standard procedure in the tech-industry, we recommend keeping NVR, DVR, and IP
camera firmware up-to-date to ensure the system is current with the latest security patches and
fixes.
“Nice to have” recommendations to improve your network security.
1. Change Passwords Regularly
Regularly change the credentials to your devices to help ensure that only authorized users are
able to access the system.
2. Physically Lock Down the Device:
Ideally, you want to prevent any unauthorized physical access to your system. The best way to
achieve this is to install the recorder in a lockbox, locking server rack, or in a room that is
behind a lock and key.
3. Isolate NVR and IP Camera Network
The network your NVR and IP camera resides on should not be the same network as your
public computer network. This will prevent any visitors or unwanted guests from getting access
to the same network the security system needs in order to function properly.
