Troubleshooting

There is no picture at night.
• Camera is capable of seeing in extremely low light conditions (0.1 Lux), but
it cannot see in total darkness. It is recommended to install the camera
where there is some ambient light (e.g. street lighting, starlight, moonlight,
etc.) or leave a light on in the area where the camera is installed.
No image at startup.
• The camera may take up to 1 minute to power up after being connected to
the NVR. Wait 2 minutes before following steps below.
• Check to ensure your camera is properly connected (see 5 Connecting the
Camera, page 5).
• Ensure the camera is connected to a router on the same network as the
NVR.
• If the camera is connected to the LAN, you must search your network for
cameras using the NVR. See your NVR's instruction manual for details.
• Make sure that the cable run is within the limitations specified in 5 Connect-
ing the Camera, page 5. All Ethernet cables must be rated CAT5e or higher.
• If using the power adapter, connect the power adapter to a different outlet.
• Ethernet cable may be damaged or not connected properly. Check your ca-
ble run or try a different cable.
• Reset the camera to factory default settings. See 10 Resetting the Camera,
page 22 for details.
No image or camera image is unclear.
• Dome cover is dirty. Clean the dome cover with a soft, slightly damp cloth.
Do not use anything other than water to clean the dome cover, as chemi-
cals such as acetone can permanently damage the plastic.
Image is distorted.
• Digital zoom is activated. Activating digital zoom may reduce the resolution
of the camera image. Zoom out completely to return to the camera's opti-
mal resolution. See 7.1 Controlling the Camera's Pan-Tilt Movement (Local
NVR), page 15 for instructions on using the zoom controls.
• Image may become unclear when camera is tilted too close to the camera
base (e.g. pointed parallel to the ceiling). Tilt the camera using the NVR or
in the FLIR Cloud™ Client software or mobile app.
Image is too bright.
