Additional sensor to solar motion sensor lights

I would like to add an additional sensor for Sunforce Solar Motion Light. http://a.co/7iWjjvX

Its currently installed on a narrow walkway on one side of the house. It will turn on now only when I reach near it, which means I need to walk in total darkness till I reach it. The idea is to add a sensor to one corner of the home so that it turn on once I reach that corner.

I can see four wires inside the "sensor" named VOD, ON, OUT & GND (attached a photo).

Could any of you suggest what sensor may work with this and how to wire it together?

If it is possible to add additional sensor, can I also try to detach the existing sensor from the fixture and move it to the other corner of the home by extending the wires? Will there be any power/signal loss if the wire length is extended?

 

Have you considered just adding a 2nd, lower intensity, light to that corner--just to light the path to the main floodlight?

I've found there are two functional types:
Those that turn on only when it "sees" you and those that stay on (dimly) all night, but get bright when it detects motion. When buying online you need to carefully read the description to determine which type it is. (guess how I know this)

 

I have a defiant light in my backyard which stays dimly lit all night and turns on with motion. Thats not solar powered though.

The issue is that there is no existing electrical wiring or outlet on one side of my home, which is why I chose a solar powered light. I can add a second solar powered light to the corner. Even in that case, I wonder if its possible to wire it together so that both lights turn on if one of it detects a motion.

 

The problem is finding an additional sensor that matches.
That runs on three batteries... 4.5v. Most motion sensors are 12v.
