Operating Instructions
1. Basic Navigation
The DVR interface is primarily controlled using the USB mouse. Right-click to access the main menu, and left-click to select options and navigate through menus.
2. Recording Modes
The DVR supports various recording modes:
- Continuous Recording: Records 24/7.
- Motion Detection Recording: Records only when motion is detected in the camera's view. This conserves hard drive space.
- Scheduled Recording: Records during specific times of the day or week.
Configure recording settings for each camera through the DVR's main menu under 'Record Settings'.
3. Video Playback
To review recorded footage:
- From the main menu, select 'Playback'.
- Choose the desired date and camera channel.
- Use the timeline to navigate through recordings. Motion-triggered events are often marked for easier identification.
4. Remote Access (Internet & 3G Phone)
The DVR supports remote viewing via Internet Explorer on a PC or through dedicated applications on 3G-enabled smartphones (Blackberry, Android, iPhone, iPad).
- Network Configuration: Ensure the DVR is connected to your router via Ethernet. You may need to configure port forwarding on your router and set up a Dynamic DNS (DDNS) service if you do not have a static IP address. Refer to your router's manual and Zmodo's online support for detailed network setup instructions.
- PC Access: Open Internet Explorer and enter the DVR's IP address. You may be prompted to install an ActiveX control.
- Mobile Access: Download the appropriate Zmodo application from your smartphone's app store. Follow the in-app instructions to add your DVR using its IP address or DDNS hostname.
Maintenance
1. Hard Drive Management
The 500GB hard drive will automatically overwrite the oldest recordings when full. Regularly back up important footage to an external USB drive if needed. You can configure hard drive settings and format the drive through the DVR's system menu.
2. Cleaning
Periodically clean the camera lenses and the DVR unit with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage surfaces.
3. Firmware Updates
Check the Zmodo official website for any available firmware updates for your DVR model. Firmware updates can improve performance, add features, or fix bugs. Follow the instructions provided with the update carefully.
Troubleshooting
- No image on monitor:
- Ensure the monitor is powered on and correctly connected to the DVR's VGA or BNC output. Verify the DVR is powered on and its power adapter is securely connected.
- Cameras not displaying video:
- Check that all camera power and video cables are securely connected to both the cameras and the DVR. Ensure the camera power adapter is functioning.
- Remote access not working:
- Verify the DVR is connected to your network. Check your router's port forwarding settings and DDNS configuration. For PC access, ensure ActiveX controls are enabled in Internet Explorer. Consult Zmodo's online support for detailed network troubleshooting guides.
- Poor night vision quality:
- Ensure there are no obstructions directly in front of the camera lens that could reflect the infrared light. The effective night vision range is up to 50 feet; objects beyond this distance may appear less clear.
- DVR not recording:
- Check recording schedules and motion detection settings. Verify the hard drive status in the DVR's system menu. Ensure the hard drive is not full (though it should overwrite automatically).
