Is it safe to get power from OBD 2 port for Dash?
You will not be taxing the power of the OBD port, which is meant to supply up to 4 amps even the dual dashcams spec out at 2 amps or below. I bought a buckline which plugs into the obd2 and it worked really well the dash camera has a fail safe so not to drain the battery if left for a long time.

Can a battery be connected to an OBD terminal?
This terminal must be connected directly (i.e., unswitched) to the DC Positive of the vehicle’s battery. This connection does not preclude the use of a fuse or other circuit protection elements.
Is it safe to get power from OBD 2 port?
This terminal must be connected directly (i.e., unswitched) to the DC Positive of the vehicle’s battery. This connection does not preclude the use of a fuse or other circuit protection elements. This circuit may be grouped with other similar circuits. This terminal must be able to supply a minimum of 4.0 A.
Can a dash cam connect to the OBD port?
So yes, the OBD port’s power pin (battery positive 16): So except for the fact that you will/could drain the battery, connecting a dash cam to the ODB II port should not give any problems.

What to do if the OBD II scanner doesn’t communicate with the vehicle?
What to do if the OBD II scanner doesn’t communicate with the vehicle. TEST 1: Connect the positive DMM lead to DLC pin 4 and the negative DMM lead to the negative battery terminal, using jumper wires if necessary. Do not connect to the body or chassis ground but to the battery terminal directly.
