5. Common failures and maintenance
5.1. Power on failure
Check if the power plug is fixed into the socket and if the power supply is working
correctly.
5.2. Image blurred
Check if the lens connector is correct. There are two types lens mounts i.e C and CS
which are different. Adjust lens focus and back focus.
5.3. SD card not working properly
Check if the SD card is fitted correctly in the IP camera and the SD card slot is not
damaged. If the system does not recognise the SD card, check if the SD card is
compatible.
5.4. What’s the relationship between the image quality, resolution and browsing
speed under different broadband bandwidths?
Under certain bandwidths, the image quality, resolution and browsing speed have a
mutual relationship. The higher the image quality, the higher the resolution, which will
inevitably consume more bandwidth. Thus browsing will become slower as resources
required become greater. In practical applications, the image quality, standard and best
browsing speed can be adjusted to suit the bandwidth available.
5.5. Unable to connect
Check if the network works correctly and if the Link led is on.
5.6. Can camera be used in a very bright glaring light?
Glare caused by direct sunlight or halogen lamp will cause the CMOS or CCD sensor to
overload and long-time exposure may burn the image sensor.
5.7. How long can the network of IP camera extend?
Generally, the LAN Cable or UTP Cable can extend to 100m.
