A:AnswerThe camera requires a compatible DVR to function. You are not abel to install the cameras pointing towards a window. There will be a white glare cause from the windows reflection.
A:AnswerI have not found any security labels that did not come with cameras. However, standard off the shelf signs work well. I prefer to let potential burglars know about the cameras and security system up front so they will decide to do their work elsewhere. I have a 20 security cameras around my place. Only 4 are fake. Another option would be to buy sticky labels at the local office supply store and print some up. They fade over time but so do the ones that come with the security systems.
