Video doorphone makers emphasize reliability, ease of use

Makers are integrating multimedia player and digital photo frame to add value.


  • Outdoor unit: Models for apartments usually include one outdoor unit, while those for villas have one or two outdoor stations. Basic releases adopt a CMOS camera with 380 TVL, and upscale varieties utilize 420 TVL CCD alternatives. Pricier kinds may come with a 3.5in LCD featuring night vision compensation to display data such as room number. 
  • Indoor unit: Makers can provide up to four indoor units for villa-use products, and as many as 256 for apartments. Indoor phones pack a 4 to 7in LCD with 320x240 to 800x480 pixels. Monitor counterparts adopt a 7in touchscreen LCD, with several new models supporting 10in TFT. Many feature A/V intercom between indoor stations. 
  • Security functions: Most indoor units can support up to eight alarm stations to alert against intruders, smoke, gas, IR, magnetic contact, and emergency, and for door and window. 
  • Add-ons: Recent releases combine A/V recording and playback, auto-answering and call transfer between indoor units. Many upscale products also integrate multimedia player and digital photo frame capability with built-in memory or external card support. Some allow visitors to leave messages.
