residential door security
When a home security system is professionally monitored, a specialist from the monitoring company is ready
to respond when sensors are triggered. If any activity triggers the alarm, a professional will
attempt to contact you and alert emergency responders to your home. The cost of professional monitoring may range from $10/mo. up to $50/mo. Depending on the home security plan and provider, you can opt for monitoring through cellular, broadband, or landline connection.
