For private residential use. They seem like a cross between a private investigator, facial recognition surveillance, CCTVs, smoke detector, meets environmental hazard detection with some mixed reviews. Saw a neighbor hire them so I looked them up but don't know what to think. Website is surprising. They seem very different from ADT or SimpliSafe which I thought would be their competitors. I'm not even sure if this type of surveillance is even legal. Don't you have to post if you have CCTVs monitoring your property? Please let me know your experience if you used them and if this type of home security is even necessary. Unless you are looking for a private investigator or private detective. Perhaps some people need a high level of security.
