Connectivity varies by model: some use wired power/data connections (including hardwired electric or Micro USB), others use wireless technologies such as Wi‑Fi or Bluetooth, and a few listings show no wireless capability.

Recording methods vary. Several intercom/door-camera listings show automatic saving to removable/expandable memory cards (examples list up to 32 GB). A few items explicitly note video-recordable capability; other listings don’t specify storage or may not include recording functionality.

Power options in the listings include hardwired AC (examples list AC100–240V) for some intercoms and battery power for others (some units list required batteries as 2 AA alkaline). Several items list no battery because they rely on wired power.

Kits and listings show various mounting options: flush and flat wall/door mounts, hardware-mounted and adhesive mounts, and included mounting accessories. Decoy cameras typically use simple screw mounting and an adjustable base for aiming.
