This set works perfectly fine, nothing wrong with it, I no longer need it.
The way the setup works is you plugin the power cords into the camera and connect them to the 12V battery that goes inside the waterproof ammo container. That way you can leave the cameras out for months at a time before having to recharge the 12V battery.
What the set includes is:
1X: J-1521 Camera - Retail: $180
2X: G-5147 Cameras - Retail: $400
4X: Power Cord PW-3617 - Retail: $ 76
3X: 12V 12Ah Battery - Retail: $ 84
Cuddeback Post Mount - Retail: $ 33
3X: 32GB SD Cards - Retail: $ 50
3X: Ammo Boxes - Retail: $ 28
All total after tax this bundle would cost about $900 I am letting it go at a fraction of that cost.
