Frequently Asked Questions - N4NRM Speco Technologies
How do I set up the N4NRM DVR for the first time?
Connect the DVR to a monitor via HDMI or VGA. Attach a hard drive (SATA). Connect cameras to BNC inputs. Power on the DVR and follow the on-screen Quick Setup Wizard to configure date/time, network, and recording settings.
How can I view the DVR remotely?
Ensure the DVR is connected to the internet via Ethernet. Enable DDNS in the network settings (default is Speco's DDNS or you can use your own). Download the Speco Viewer app on your smartphone or use a web browser to log in using the DDNS address or public IP.
What type of hard drive is compatible?
Use a 3.5-inch SATA hard drive recommended for surveillance (e.g., Western Digital Purple or Seagate SkyHawk). The maximum supported capacity is 6TB. The DVR does not come with a drive.
How to reset the DVR to factory defaults?
Go to Menu > Settings > System > Factory Reset or press and hold the Reset button on the rear panel (if available) for 10 seconds while the unit is powered on. This will erase all settings and recorded data.
Can I use PoE cameras with this DVR?
No, the N4NRM supports only analog HD-TVI or CVBS cameras via BNC connectors. It does not have PoE ports. For IP cameras, consider a Speco NVR model.
How to update the firmware?
Download the latest firmware from the Speco Technologies support website. Copy the firmware file to a USB flash drive. Insert the drive into the DVR, go to Menu > Settings > System > Upgrade, and select the file.
Why is there no video on the screen?
Check that cameras are properly connected and powered. Ensure the monitor input source matches the DVR output (HDMI/VGA). Go to Camera Management to see if channels are enabled. If still no video, try a different camera or cable.
How do I set motion detection for email alerts?
Go to Alarm > Motion Detection. Enable motion detection for desired channels. Set sensitivity and area. Then configure Email settings in Network > SMTP with your email credentials and server address.
What mobile app is available for remote viewing?
Use the Speco Viewer app, available for iOS and Android. Download from the App Store or Google Play. Add the DVR by entering its DDNS address or IP, user name, and password.
How many days of recording can I store?
This depends on the hard drive size, recording resolution, frame rate, and number of cameras. With a 1TB drive, recording all 4 channels at 1080p 15fps continuously, you can store approximately 7-10 days. Use motion detection to extend storage time.
