• Auxiliary power (DC output)

• Digital Input

•Digital Output

•0 V DC (-)

Function	Pin	Notes	Specifications
0 V DC (-)	1		0 V DC
DC output	2	Can be used to power auxiliary equipment.	3.3 V DC
		Note: This pin can only be used as power out.	Max load = 50 mA
Digital Input	3	Connect to pin 1 to activate, or leave floating (unconnected)	0 to max 40 V DC
		to deactivate
Digital Output	4	Connected to pin 1 when activated, floating (unconnected)	0 to max 40 V DC, open drain,
		when deactivated. If used with an inductive load, e.g. a relay,	100 mA
		a diode must be connected in parallel with the load, for
		protection against voltage transients.

SD Card Slot

The Axis product supports microSD cards with up to 64 GB of storage. For best recording performance, use ultra-high speed microSD cards (microSDHC UHS-I or microSDXC UHS-I).

Performance Considerations

When setting up your system, it is important to consider how various settings and situations will affect performance. Some factors affect the amount of bandwidth (the bit rate) required, others can affect the frame rate, and some affect both. If the load on the CPU reaches its maximum, this will also affect the frame rate.
