Overview of Select Engineered Systems telephone entry systems

Telephone entry systems are one of SES’s most popular products. They’re intended to be durable and simple building entry solutions for both residential and commercial properties.

SES offers two telephone entry models:

  1. TEC1 Basic Telephone Entry System: The more basic model.
  2. TEC2 Telephone Access: A slightly more advanced model.

Both the TEC1 and TEC2 models are similar in appearance and functionality. The only difference appears to be certain capacities and features.



  • 2-, 4-, or 10-line LCD displays (10-line display only available in TEC2)
  • Tenant phone number capacity varies depending on the model from 50 to 1,000
  • Numeric keypad
  • Comes standard with two relays and board-level surge suppression
  • Two-year limited warranty
  • Stainless steel front door and aluminum back box
  • Card access capability optional
  • Programmable via keypad
  • SELCOM basic software (may be able to upgrade to SELCOMPRM, the premium software)
  • Can be pedestal mounted — ideal for doors and gates where there is no suitable wall for installation
  • Optional weather hood

  • No mobile app
  • Lacks smartphone-based access capabilities
  • Outdated software that isn’t cloud-based (you must download it to one device)
  • Most accessories may be sold separately
  • Must be programmed manually using the device’s keypad or with outdated SELCOM software
  • May require a telephone line
  • No touchscreen

Comparison of Select Engineered System telephone entry systems with ButterflyMX video intercoms

SES telephone entry systems are an option if you’re looking for a basic access control solution, but they’re not as powerful compared to modern video intercoms like ButterflyMX.

Although SES telephone entry systems may be scalable, they may not have the advanced features and seamless functionality that modern tenants and property managers seek. SES telephone entry systems may be cumbersome and hard to manage, whether you manage the system manually using the device’s keypad or remotely using outdated SES software.

What’s more, Select Engineered Systems’ telephone entry systems may not provide a convenient access experience for tenants. Since there is no mobile app, tenants can’t open the door or gate for themselves using their smartphones. Perhaps the only main feature SES telephone entry offers is a way for tenants to remotely grant access to visitors. And even then, there is no camera for video calling and added security.

In contrast, the ButterflyMX video intercom offers a robust mobile app, two-way video calling, a digital audit trail, and convenient features like virtual keys and Delivery Passes for managed visitor access. Additionally, the property staff can manage the intercom through the powerful ButterflyMX OS, which is a completely cloud-based software for on-the-go management.

In the long run, solutions like SES telephone entry systems aren’t as effective for modern residential and commercial buildings. Their entry systems may not offer comparable levels of security and convenience compared to solutions like ButterflyMX.
