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.
Most of the devices are costly and need regular maintenance for efficient working. Installing metal detectors in schools can increase the budget to a great extent. The cost of a single device can be around USD 4,000, and the schools may have to buy several detectors for complete security.
