Note: DVR recordings are saved in the Hard Drive of your DVR. The first thing you must check is if the Hard Drive is working properly.
1. Pre-Installed HDD
Verify your system specs if your DVR has a pre-installed Hard Drive. Some models are sold with no Hard Drive installed and customers must install it. If you need help installing the HDD, please, follow this link Installing or Upgrading the HDD
2. Hard Drive Status
If your DVR has a pre-installed Hard Drive, please, check if it has been detected, is formatted and still has free space to save recordings.
To check the HDD Status, please refer to this link THD Series: Hard Drive Issues
3. Record Schedule
If you have already checked that your Hard Drive is working fine but you are still having problems with Playbacks, you need to check the Record Schedule. By default, the DVR is set up to record 24/7 when motion is detected, but if this feature has been changed, the DVR will probably not record on specific days and hours. Check the DVR Record Schedule to make sure it is set up as desired for each individual channel.
3.1 For THD Series DVR
• Right-click anywhere on the screen and the drop-down menu will appear
• Click on Recording Schedule (You may need to log in after this step)
Green squares represent Motion Record, Blue squares Continuous Record and Black squares No Record. If Black squares are selected for certain days and hours, the DVR will not record at this time.
4. Playbacks Time
If you have already checked that your Hard Drive is working fine and Record Schedule is configured as desired, but you are still having problems to find recordings, you may be having issues with the Playback Time.
For example, if you are pretty sure that an event (ex: motion detection) has occurred at a specific time, but at this time there is nothing recorded in your DVR. For this case, the problem could be that the DVR date and time is different or not synchronized with the local time. That is why Playback time is different from the time selected on DVR recording Search.
To learn how to solve this issue, please go to THD Series: Date and Time issues
Another problem with playback time occurs when you try to find old recordings if the date you are looking for is before the oldest date on recordings. If this occurs, the DVR will indicate that to continue recording new events, the file you are looking for has been overwritten.
5. Camera PIR sensor
If you are having problems with playbacks of a specific channel and this channel has a connected PIR camera, you must ensure the PIR feature of the camera is working properly. Recordings on PIR cameras not only depend on Motion, it also depends on PIR detection. For this case, please go to Analog Cameras: PIR Detection Issues
