Bad image quality of the recording
• Set a higher image quality or resolution; see chapter 14 c).
Motion detection is not working correctly
• The screen/DVR has two different types of motion detection - based on changes in the camera image (see
chapter 12. b) and based on heat changes in the recording area of the PIR sensor (see chapter 12. c).
Both types of motion detection have benefits and disadvantages; the most important items are:
1: Motion recognition based on changes in the camera image
Benefits:
Disadvantages:
2: Motion recognition based on heat changes in the recording area of the PIR sensor.
Benefits:
Disadvantages:
• Use a different sensitivity setting.
• Align the radio camera differently.
• The monitoring area of the PIR sensor is a little larger than the opening angle of the camera lens. For this
reason, it may happen that, e.g., no persons are visible in the recorded surveillance video.
microSD/microSDHC memory card is not recognised
• The screen/DVR can only be operated with memory cards up to 32GByte. Use of SDXC memory cards is
not possible.
• The screen/DVR can only handle the file format FAT or FAT32, but not, e.g., NTFS.
• Format the memory card with the corresponding function of the screen/DVR, see chapter 11. c); all data
on the memory card will be lost.
• Select the right data carrier for saving (either memory card or USB data carrier; see chapter 11. d).
• Remove the memory card and insert it again.
• Use a different memory card.
• Switch off the screen/DVR and then on again.

Independent of ambient temperature
Independent of the temperature of the moving object
False alarms, e.g. from moving vegetation (at too-sensitive setting) or from fast
brightness changes (e.g. sun/clouds)
Hardly any influences from moving vegetation (since, e.g., leaves/branches have the
same temperature as the environment) or brightness changes
Dependent on the ambient temperature (in summer only slight temperature differ-
ence, e.g. house wall and body surface of a person)
Dependent on the size and temperature of the moving object (e.g. in winter, problems
must be expected due to insulating clothing)
