Frequently Asked Questions - N4NRN Speco Technologies
How do I set up the N4NRN NVR for the first time?
Connect the NVR to your network via Ethernet, attach a monitor to the HDMI port, and power it on. Follow the on-screen wizard to configure network settings, create a password, and add cameras.
What hard drives are compatible with the N4NRN?
The NVR supports one 3.5-inch SATA hard drive up to 8TB. Use surveillance-grade drives (e.g., WD Purple or Seagate SkyHawk) for 24/7 operation.
Can I access the NVR remotely from my smartphone?
Yes, download the Speco Technologies app (iOS/Android). Add the NVR by scanning the QR code on the device or entering its IP address and login credentials.
How many cameras can the N4NRN support?
It supports up to 4 IP cameras via PoE (Power over Ethernet) on the built-in switch, plus additional cameras through the network if using a separate PoE switch.
What is the maximum recording resolution?
The NVR can record at up to 4K (3840x2160) resolution, depending on the camera capabilities. Recordings are compressed using H.265 or H.264 codecs.
How do I reset the NVR to factory defaults?
Press and hold the reset button (usually located on the back panel) for about 10 seconds using a paperclip until the system beeps or reboots. This clears all settings and passwords.
The NVR is not detecting my cameras. What should I check?
Ensure cameras are connected to the PoE ports and powered on. Verify that the cameras are set to DHCP or have IPs in the same subnet as the NVR. Check that ONVIF compatibility is enabled on the cameras.
Can I view live footage on a web browser?
Yes, open a web browser (Chrome, Firefox, Edge) and enter the NVR's IP address. Use the login credentials set during initial setup. For live view, you may need to install a plugin or use the built-in HTML5 viewer.
How do I update the firmware on the N4NRN?
Download the latest firmware from the Speco Technologies support website. Log into the NVR's web interface, go to System > Firmware Update, and upload the file. Do not power off during the update.
What should I do if I forget the admin password?
You will need to perform a factory reset (see question about reset). This erases all settings, including the password. After reset, set a new password and reconfigure the NVR.
