Keypads lack the communication functionality of Door Phones. They are only meant to to allow workers to enter an office and keep track of them.
The main distinction for keypads is if they contain proximity sensor or not. A proximity sensor allows for entry using a magnetic card. Without it a worker will need to enter an access code. Keypads with proximity sensors can still have increased security mode that require a simple code to be entered even with the magnetic card verification.
Other considerations when buying a keypad are:
- Number of user codes - that depends on the size of your office. For example if you have two hundred employees, a keypad that only supports one hundred codes may not cut it (assuming you want each employee to have a different code for accounting purposes instead of sharing codes). For most keypads, with at least 1000 users, this should not be an issue. But still keep an eye out on this specification if the keypad is needed for a large facility.
User codes can usually be programmed to be between 4-8 digits. A shorter one is obviously riskier, while a longer one will be harder for user to remember.
Some keypads allow for temporary visitor codes in addition to employee codes.
- Weatherproof - like Door Phones, if the keypad is going to be used in an outdoor environment, rather than in a corridor inside a building, you would want it to have weatherproof construction.
- Illuminated keypad - this is also an important feature if the keypad is intended for outdoor or dimly lit areas.
