Lockit comparison: Which Lockit device does what?

  • Updated

All current Lockit devices are based on the same highly accurate, temperature-compensated crystal oscillator and communicate with each other via ACN (Ambient Communication Network). They differ in size, connections, operation and power supply. This overview compares the five devices. Status: October 2026.

The five Lockits at a glance

Device Model In short
NanoLockit ACN-NL-L The smallest timecode box of the Lockit family, with logging feature. The go-to solution for DSLR cameras or gimbal rigs.
Lockit ACN-CL Timecode and sync generator with OLED display and an output for genlock and wordclock.
LockitBT ACN-LB Like the Lockit, plus Bluetooth: remote control via the LockitRemote app and timecode for third-party devices via Bluetooth.
LockitSlate Take 2 ACN-LS2 Timecode clapperboard with LED timecode display and built-in timecode generator. The display module also works as a standalone display.
Lockit+ ACN-LP Timecode and sync generator with WiFi and web interface: advanced generator settings, monitoring of all Lockit devices in the ACN and a hub for metadata.

What all Lockits have in common

  • All timecode frame rates: 23.98 / 24 / 25 / 29.97 / 29.97 DROP / 30 / 47.95 / 48 / 50 / 59.94 / 59.94 DROP / 60 FPS
  • ACN: proprietary 2.4 GHz network with 15 selectable channels (11 to 25)
  • Accuracy: less than 1 frame of drift within 24 hours, zero drift with active C-Jam
  • Single Jam: hold the green button for 3 seconds and all Lockits on the same ACN channel take over timecode and frame rate
  • TX Mode: the Lockit follows an external timecode source and broadcasts its timecode, start and stop via ACN
  • Plug & Play: connected to the TC output of another device, a Lockit takes over timecode and frame rate automatically
  • Operation: three buttons (power, red, green) and an RGB status LED
  • Timecode in and out via 5-pin port (Lemo-compatible)
