The MailMon system is comprised of two devices: MailMon-In and MailMon-out.
The MailMon-In device is plugged into a regular power outlet inside of the home or office. When mail arrives, MailMon-In will beep and blink to indicate that it’s time to check the mail.
The MailMon-Out device resides inside of the mailbox. MailMon-Out senses when mail arrives. Using a unique RF network, MailMon-Out sends a notification that mail has arrived. MailMon-Out is powered by 3 AAA batteries. Battery life is 6 to 8 months.
The MailMon system is available in a short-range version with a range of 300 feet and a long-range version with a range of ¼ mile.
