Seven recorders, one question: which one for your need?
The same table for all of them, with the values of the current datasheets. Start from the situation that looks like yours; the table then confirms the detail.
Which one for what
Six situations we meet every week, and the product that answers each.
None of them looks like yours? Be guided, in three questions →
-
A flight-test campaign with many sensors, buses and a telemetry link, on one time base
NanoX: up to sixteen acquisition modules, recording and transmission in the same unit, master and satellite units over Ethernet.
View the product : D.T.MUX NanoX → -
A compact flight-test recorder in Chapter 10, without telemetry
NanoX without its transmitter module: the same stackable acquisition and Chapter 10 recording, and the link can be added later. It replaces the NanoS2, no longer sold.
View the product : D.T.MUX NanoX → -
Recording buses, audio and video on a mission aircraft, with the data leaving in a secure cartridge
Nano: one kilogram, removable cartridge with encryption, quick erase and physical destruction options.
View the product : D.T.MUX Nano → -
Long missions, very large capacity, 4K video at 60 fps, files served to the network
M: cartridges up to 16 TB, H.264 / H.265, built-in file server, ARINC 404 rack or cockpit mounting.
View the product : D.T.MUX M → -
Video only, several cameras, replay on board
DVR: up to four HD / 4K channels, simultaneous record and replay, HD-SDI in and out.
View the product : D.T.MUX DVR → -
A regulatory requirement for crash survivability: flight data, cockpit audio, images
Sentinel ED-112 for certified aircraft; Sentinel ED-155 where the lightweight specification applies, helicopters, light aircraft, drones.

The same criteria for each
Values come from the product pages and datasheets; a dash means the feature does not exist on that product, “on request” that the sheet does not state it.

And for acquisition without a main recorder?
The COD-R is an ultra-miniature acquisition and telemetry system, up to 128 channels in real time with an S-band transmitter and an optional internal SSD. It is not in this table because its job is transmission, but it completes the same chain. See the COD-R →
Still two candidates?
Describe the aircraft, the streams to record and the mission duration: we decide with you, and we say why.
