Chapter 4 Troubleshooting and Useful Tips
Connecting Directly To Laptop or PC
In a typical scenario cameras are connected using network cables to a
network switch. A camera can also be connected to a PC or laptop
directly. Be sure to use a cross-over network cable between the camera
and PC when connecting in this fashion.
When a camera is connected directly, in some cases you may need to
change TCP/IP configuration on your PC. For example, configure the PC to
work with a static IP address.
When a PoE injector is used and connected directly to a PC there are two
networking cables, one cable connects the PC to the PoE injector; the
other connects the injector to the camera. Only one of these cables must
be cross-over. The other cable must be regular, not cross-over.
Note:
MP8D cameras require a higher PoE power class (Class 3: from 6.49 to 12.95 Watt) than
other MP camera models.
Switches and Routers
Note that some Gigabit switches and network adapters incompletely
emulate 100BaseT signaling levels and may not work correctly with high
bandwidth 100BaseT equipment.
Low Sharpness
If the image sharpness appears to be low:
• Check if the lens is in focus.
• Check if the lens is appropriate for a mega-pixel camera.
• Under Image Quality menu decrease compression and increase
sharpness.
• Check if the lens iris is fully open or closed down too much. For best
resolution and depth of field the iris (depending on lens make and
model) should be closed by 2-3 F-stops.
