Ans: The total number of cameras you need for optimal home security depends on the size and layout of your home, the number and location of entry points, and the areas that you want to monitor. Here are some general guidelines that can help you determine the ideal installation placement and number of cameras that you need to get: *Cover the main entrance and exit points, such as the front door, back door, garage door, and windows that are easily accessible from the outside. *Place cameras in high-traffic areas, such as the living room, kitchen, hallway, and staircase, where you can see who is coming and going. *Position cameras in strategic angles, such as corners, ceilings, or walls, where they can capture a wide view of the room and avoid blind spots. *Consider the lighting conditions, such as natural light, artificial light, and night vision, and adjust the camera settings accordingly to ensure clear and quality footage. *Avoid placing cameras in areas where they may violate privacy, such as bedrooms, bathrooms, or closets unless you have a specific reason to do so.
