How do you know if your neighbor is illegally using a surveillance device on you, and what can you do to stop them?
user
If you suspect that your neighbor is illegally using a surveillance device on you, you can take steps to find out for sure and to stop them from doing so. First, you should regularly check your home for any signs of a surveillance device, such as strange lights or sounds coming from the wall or from the sky outside your home. If you detect any unusual activity, call the police and explain your suspicions. You can also take steps to physically search around your property and scan wireless networks in order to discover any suspicious equipment.

In addition, if the situation continues and it becomes reasonable to suspect that someone is surveilling your home without consent, you should take additional measures such as installing secure web services such as virtual private networks (VPNs), implementing network intrusion detectors, disabling unnecessary services on networks – including Wi-Fi hotspots- making sure all software applications are properly updated regularly with newest security patches and so on.

Ultimately though — if evidence proves illegal surveillance activity has taken place - the best way to stop it is by contacting law enforcement authorities responsible for investigating these types of cases. They will likely launch an investigation and attempt to determine who is responsible before filing criminal charges where appropriate

If you suspect that your neighbor is illegally using a surveillance device on you, you can take steps to determine the accuracy of your suspicions. You can use signal detectors, such as a Wi-Fi connection or audio picks up and listen for suspicious noises. Additionally, if you see any strange activity near your home that could be indicative of surveillance devices being used, such as seeing someone carrying around unusual looking equipment or planting something near your home it's also worth investigating. 

You should contact a lawyer to learn more about how best to proceed if confirmed that someone is using a surveillance device on you without consent.
