What is the preferred installation method for window contacts?

The preferred installation method for window contacts is surface mounting. This technique involves affixing the contact directly to the window frame or the window itself, making it easy to install and maintain. Surface mounting is often chosen for its simplicity and effectiveness, as it ensures that the contact is readily accessible for inspections or adjustments.

Recessed mounting, while also effective, requires more installation effort as it involves cutting into the window frame to hide the sensors. Overhead and hinge mounting are less common and typically not ideal for window contacts, as they don't provide the same level of effectiveness in detecting openings or unauthorized access. Surface mounting stands out because it can be quickly implemented without intrusion into the structure, allowing for easier monitoring of window security.
