OVERVIEW
The Guardian DVR TVI (GDVR TVI) system operates with an embedded LINUX operating system for increased stability. It also uses standard H. 264 video compression and G. 711 audio compression technology which provide high quality, detailed playback and analysis. TCP/IP network technology provides the GDVR TVI system with strong network data transmission and remote control operation.
The GDVR TVI works as a stand-alone surveillance system or as part of a larger surveillance network. Its professional network video surveillance software provides strong network communication and telecommunication ability.
ABOUT THIS MANUAL
This OM provides operating procedures for the GDVR TVI system. The GDVR TVI models operate identically. There are only 2 differences between the models: the number of channels and the number of cameras.
• GDVR 4T40: 4 outdoor cameras, 4 channels.
• GDVR 8T40: 4 outdoor cameras, 8 channels.
• GDVR 8T80: 8 outdoor cameras, 8 channels.
All procedures apply to all models unless specifically noted. Some screen illustrations show entries for all 8 channels and some show for only 4 channels.

(For the initial set up, a series of Wizard screens pop up. Change the default parameters, if necessary, if not, click Next, till you reach the screen that displays Finish. Click Finish.)
System Login

Required Settings
Set the system date and time so recorded files will be correctly time stamped. Next, create a password for the "admin" user.
Set Date and Time
The correct date and time are critical for the timestamp on recorded files. If the timestamp is incorrect, searching for a specific recorded file will be difficult.
From Main Menu/Setup/Basic, select the Date & Time tab. See page 31 for detailed descriptions of the tab's fields.
Set Password
Passwords prevent unauthorized access to system configuration screens. The Admin user originally has no password so you can log into the system for setup.

From Main Menu/Users/User Management, select the Password field. See page 54 for a detailed description on how to set up a password.
Default Operation Settings
Uniden's default settings allow you to begin monitoring your network immediately. After you have monitored your network for a week or two, you may find you need to slightly adjust your settings. For example, you may need to mask areas from motion detection (trees, etc).

FIRMWARE UPDATES
From time to time, Uniden may update its products' firmware to improve features, fix bugs, or otherwise improve the product. Uniden recommends checking for firmware updates every 6 months.
Check for firmware updates if you have service issues; your firmware may be out of date.
- Go to Main Menu/Information/System Information to locate the current GDVR firmware version.
- Go to uniden.com.au and look for the GDVR. Check your DVR's firmware number against the latest firmware download available.
- If there is a firmware version that is later than the firmware version on your system, download it to your USB drive.
- Power down your DVR.
- Insert the USB drive into the USB port on the BACK of the receiver.
Do NOT insert the USB drive into the USB port on the front of the receiver. - Power up your DVR. The system reboots and imports the new firmware.
TROUBLESHOOTING
After turning on, the DVR cannot switch on normally.
Possible reasons:
• The power supply is not correct.
- Switch power cable is not in good connection.
- Switch power is damaged.
• The program upgrading is wrong.
- The hard disk is damaged or something is wrong with the hard disk cables.
- Something is wrong with the front panel.

The DVR reboots automatically or frequently stops working after booting up for a few minutes
Possible reasons:
- The input voltage is not stable or too low.
- The hard disk is damaged or the hard disk cables are broken.
- The power rating from wall supply is not correct.
- The front-end video signal is not stable.
- Poor heat dissipation, too much dust, bad running environment for the DVR.
- Something is wrong with the hardware of the DVR.
Cannot detect hard disk after switch on.
Possible reasons:
- The hard disk power supply cable is not connected.
- The cables of the hard disk are damaged.
• The hard disk is damaged. - The SATA port of the main board is damaged.
No video output in single channel, multiple channels and all channels.
Possible reasons:
- Video format incorrect. Please ensure it is set corerctly, either PAL or NTSC. (Australia = PAL).
- The image brightness is all 0. Please restore the default setup.
• There is no video input signal or the signal is too weak.
• The hardware of the DVR is damaged.
Real-time image problems such as serious distortion of the image color or the brightness, etc.
Possible reasons:
- The DVR does not match with the impedance of the monitor.
- The video transmission distance is too far or the attenuation of video transmission cable is too big.
- The setting of color and brightness for the DVR is wrong.
Cannot find video files in local playback.
Possible reasons:
- Something is wrong with the data cable or the jumper of the hard disk
• The hard disk is damaged or no video data. - Record function has been disabled. Please click Record icon under Setup to enable it.
- The video files you want to see have been overwritten after a recent disk format.
Blurred screen when viewing the local video.
Possible reasons:
• The video quality is set too low.
- The program data reads wrongly, always become normal after rebooting up the DVR.
- Something is wrong with the data cable or the jumper of the hard disk
• The hard disk is damaged.

- Something wrong with the front-end PTZ.
- The baud rate, address, protocol settings of the front-end PTZ and device PTZ are inconsistent.
• RS485 cable is connected incorrectly. - When multiple decoders are connected, the far end of AB cable of the PTZ decoder must add a 120 OU resistance to remove reflection and impedance matching, otherwise it will make the PTZ control unstable.
The motion detection is not working
Possible reasons:
• The time period setting is not correct.
- The motion detection area setting is not appropriate.
• The sensitivity is too low.

APPENDIX O. HARD DISK CAPACIPLCALSIATION
Make sure the hard disk is installed and successfully formatted when install the DVR for the first time.
- The capacity of the Hard disk itself
We recommend hard disk of 500G\~2T for better stability.
- Total Capacity Option
The calculation formula of hard disk capacity is:
Total capacity(M) = channel numbers*time(hour)*occupied capacity for an hour(M/hour)
Similarly, the calculation formula of recording time is:
Recording time(hour)= Total capacity(M)
Occupied Capacity for an hour(M/hour)*the channel numbers
The DVR introduces the H.264 compression technology. Its dynamic range is very large so the hard disk capacity calculation is based on the stream to count the estimated values of files created by each channel in an hour.
Example:
For a 500G HDD, real-time CIF recording, it can keep recording for about 25 days. The occupied space of HDD for single channel is 200M/H, if 4channels real-time CIF recording for 24hours, the estimated recording days is: 500G/(200M/H*24H*4ch)=26 days
