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benetsanddisadvantages;themostimportantitemsare:

1: Motion recognition based on changes in the camera image (see chapter 12. b):

Benets: Independentofambienttemperature

Independent of the temperature of the moving object

Disadvantages: False alarms, e.g. from moving vegetation (at too-sensitive setting) or from fast brightness changes

(e.g. sun/clouds)

2: Motion recognition based on heat changes in the recording area of the PIR sensor (see chapter 12. c):

Benets: Hardlyanyinuencesfrommovingvegetation(since,e.g.,leaves/brancheshavethesametem-

perature as the environment) or brightness changes

Disadvantages: Dependent on the ambient temperature (in summer only slight temperature difference, e.g. warm

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)

• Use a different sensitivity setting.

• Align the radio camera and the aerial 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.

• The objects crossing the monitoring area are too fast.

MicroSD/MicroSDHC memory card is not recognised

• The screen/DVR can only be operated with memory cards up to 32 GByte. Use of MicroSDXC memory cards is

not possible.

• Thescreen/DVRcanonlyhandletheleformatFATorFAT32,butnot,e.g.,NTFS.

• Format the memory card with the corresponding function of the screen/DVR, see chapter 11. e); all data on the

memory card will be lost. Depending on memory card size, formatting may take a while.

• Select the right data carrier for saving (either memory card or USB data carrier; see chapter 11. f).

• Remove the memory card and insert it again.

• Use a different memory card.

• Switch off the screen/DVR and then on again.

Bad image quality of the recording

• Set a higher image quality or resolution; see chapter 14. c).
