Lot of 2 VTech VM342-2 Baby Monitor Video Cameras 6-volt version

Description

For sale is a pair of VTech VM342-2 replacement baby monitor video cameras.
These are the 6-volt version, please validate what yours are as there are 2 versions and they're not compatible. I believe the other type is 5 volts.
There are 4 cameras in total available.  Two sets of 2 cameras. Each quantity is for 1 pair.
Includes:
2 cameras
2 power adapters
2 wall mounts
The cameras are used but in very good condition. The monitor broke after i dropped it down the stairs so we don't really need the cams anymore.
