Well depends on a lot of things on a Second keypad, If your house is a larger home you could put the Second keypad in a bedroom,where the base station may not be heard. The keypads have speaker on them which alert you of enter/exit delay, if you have that setup. In my situation I need 2 keypads one is by the garage door as you exit the home the other is in the bedroom hallway . At night when I set the alarm it’s put into home mode but it will also use the motion sensors in my living room,kitchen and basement and these sensors are setup for a no Delay ,so once triggered it immediately sounds the alarm,having the keypad in the bedroom hall prevents tripping the alarm. So it really depends on house size and how you wanna setup system I like to have my motion sensors on at night. so I need second keypad in the bed hall,also note the system will alert for 30 seconds if there is a security breach if the system is not dissed armed rapid response will call you after 30 seconds . However the signal is sent immediately .
the ring keypads are a mat white.. Costco keypads are like a glossy, white. So if you don’t like glossy white I wouldn’t go with costco
