Hardware costs and manpower costs. Portal metal detectors vary widely in price. Portals on the market range from as little as $1,000 up to as much as $30,000. The moderately-priced models around $4,000 to $5,000 probably offer the features and reliabilities required for a school metal detection program. Models closer to $1,000 are not recommended due to lack of sensitivity of these devices.
Cost: Low The cost of motion detectors range from $10 to $150, depending on the type, features, and style of the light you choose. Installing a motion-sensor on one 500W outdoor flood light can save up to $180 a year which means your investment will pay for itself in less than one year! Time and effort: Moderate Installing a motion detector can be a fairly quick task, only taking around 20-30 minutes.
