Our security systems can be equipped with cameras to provide an image on TV sets within the home or over the internet. Their uses are varied. Some of the most popular areas where they are used are for placement at the front and/or back door to identify visitors or intruders, and installation along outside walls or gates. They also can be used indoors for mothers or caretakers to view activity in a pool area, or they may be placed out of sight to monitor childcare.
