What are they taking you to court for? Not that any of us are lawyers and competent to give legal advice.
I'm a lawyer...but not one in your state (unless you're in TN), and I can't give you advice without fully knowing the exact details. And I am not an expert in general property disputes. (I'm just starting out, and plan to specialize in Intellectual Property law) However, from my own experience in digital surveillance, I can tell you that it is extremely difficult to alter a video. Although the tapes could be altered, I doubt that they did alter it. Changing each frame to add a person is very difficult and time consuming. More likely, they staged it or mistook your husband for someone else, or they used footage from a time when he was permitted to enter the property. Either way, a jury would be the one to decide that evidence is not what it seems to be.
Regardless, in a first time tresspass civil law case, they will probably just get nominal damages unless some damage was done to your property (likely a few dollars, definitely less than the court fees.) They will be able to get an injunction against future trespasses as well if they are worried about you trespassing on their property.
Many states do not have laws against recording footage that you expect to be private, but some do. If you are concerned about the recorded video being an invasion of your privacy, you really need to talk to a lawyer that is familiar with laws of your state about countersuing...possibly on grounds of intrusion of seclusion. Its definitely an issue that differs from state to state, and therefore you need to talk to an attorney.
I have infrared cameras, but they are aimed only at my driveway and my own property, and their intent is for my own personal security. I happen to catch some of my neighbor's property in the video as well, but it is perfectly legal . If your neighbors cameras are intended to protect their own property, then they are probably okay. If they are intended for spying on you, then they might not be acceptable. Most likely your neighbors can't use activity on your own property against you based on their footage...but once again the law in this area is new, and each state is different.
