You can start a company from your home that monitors home and business building alarms. When a customer's alarm goes off, it will ring your house. You then call the customer's special contact number to see if everything is all right. If it is, you will be given the predetermined code word. If not, you will call the police.

Tip You will need to have a separate telephone line for this service.

The average monthly cost for home security monitoring services is $30/month ($360/year). Monitoring prices can be as low as $9.99/month ($120/year) for basic monitoring, and upwards of $100/month ($1,200 annually) for more premium.
