DIY WiFi Home Security System

Place a wireless video camera on a chair or on a table or bookcase facing a location that should be monitored, for example, the front door or a glass window leading to a balcony. Plug the power supply that is included with the video camera into the power port of the video camera and into a wall socket for power. Extend an external antenna if one is present.

Set up the second wireless video camera in the same manner as the one already done, only in a different location.

Place the wireless video receiver in a location where you can view the image from the video camera, for example, your bedroom or in a den. Plug the power supply that is included with the wireless video receiver into the power port of the video receiver and into a wall socket for power. Extend an external antenna if one is present.

Cover over any lit LED on the front of the camera that would betray its presence with a strip of masking tape.

Insert one end of a composite video cable into the composite video cable output on the video receiver. Insert the other end of the composite video cable into a composite video on the back or side of a television set.

Turn the television on with its remote. Press the "Menu" button. Select the "Video input" menu and select the composite video input from the submenu. Press the "Menu" button to exit the settings.

Turn the wireless video receiver on. Select between the two video cameras by sliding the selector switch from one setting to another or by pushing different 'Video selection" push buttons, depending upon the type of wireless video receiver you are using.
