2 lights caught on my security camera.

I was getting ready for bed and usually check all of our outdoor security cameras. I noticed something unusual about what appeared to be 2 lights moving together over the cow pasture. At first I thought it was bugs flying but realized that they traveled together in uniform, but they seem to have there own Independant movement. I tried to shift the camera a little to follow them, which is seen in the video. They appeared to come towards the house in which they get larger do to perspective. At one point the camera seemed to have a glitch and the two light stay in one frame. They then shoot up off out of the frame. Not sure really what is was.
