Text Overlay - Serial

Text Overlay - Serial

Idealpos interfaces with DVR/NVR to produce text overlay. Note that most DVR/NVR systems have a POS Interface box that is required; here are some we frequently see in the market:

  • Dedicated Micros Sprite2
  • GeoVision
  • HikVision
  • Nuuo NVR Solo

Idealpos outputs ASCII text to an IP/Port or Serial port. Many NVR/DVR Systems accept this type of input in the market. This is commonly referred to as Epson Emulation; however, it is not guaranteed that Idealpos will work with every camera system that claims to have this emulation.


This configuration should be able to be used to provide a text overlay to a security DVR System. These settings are just a guide to what Idealpos has found works with most text overlay systems. You may need to discuss the requirements further with the security system provider.
