JM-G4240C is a 4 MP module with a 6.8–272 mm autofocus lens and 40× zoom. Fit the long lens, 36-pin FFC cable and selected serial controls inside a host-built enclosure.
JM-G4240C is a 4 MP IP zoom module with a 6.8–272 mm autofocus lens and 40× optical zoom. The table lists up to 2688 × 1520 at 25 fps, three streams, H.265/H.264/MJPEG, ONVIF and GB/T28181, one alarm input/output, TF storage up to 256 GB, a 36-pin FFC interface, RS232/VISCA, RS485/Pelco and DC 12 V power.
JM-G4240C is a module; the host supplies enclosure and mounting. Start with 4 MP/40× stream plan.
Define 4 MP/40× stream plan before encoding or storage choices.
The stated use is integration into a project-built camera or imaging assembly that needs long optical zoom and IP video. That scope does not establish compatibility with a particular housing, recorder, VMS or PTZ assembly.
Place 128.5 × 60 × 72 mm and 36-pin cable on the host drawing with lens and cable clearance.
Map DC 12 V, VISCA and Pelco to the schematic and verify electrical details.
Account for JM-G4240C power at the host connection. The finished housing, rather than the module, must address sealing and thermal control.
Send the 4 MP/40× stream plan, 128.5 × 60 × 72 mm envelope, 36-pin cable route, DC 12 V supply and selected VISCA or Pelco functions. Keep Weight pending.

Evaluate JM-G4240C beside entries in the Camera Module category for the 4 MP/40× stream plan. Fit the 128.5 × 60 × 72 mm body and 36-pin cable first, then verify DC 12 V and the chosen VISCA or Pelco route.
Begin with 4 MP/40× stream plan.
Check DC 12 V, VISCA and Pelco against required host functions.
Show 128.5 × 60 × 72 mm and 36-pin cable, cables and clearances.
Keep the blank Weight item pending until a product-specific value is provided.
The optical decision is a 4 MP plan using the 6.8–272 mm autofocus lens and 40× zoom. The page lists up to 2688 × 1520 at 25 fps and three streams. Assign those streams to real host functions before selecting encoding and storage settings.
Place the 128.5 × 60 × 72 mm body on the internal drawing and reserve the travel, connector and bend space required by the 36-pin FFC cable. The Weight field has no value, so the host load calculation must keep module weight pending rather than importing a figure from another model.
Map DC 12 V, RS232/VISCA, RS485/Pelco and alarm I/O to the receiving board. TF storage up to 256 GB can be used only within the defined recording architecture. The host must provide its own enclosure, sealing, mounting and thermal solution.
Compare the lens envelope, three-stream plan and serial-control route before releasing the JM-G4240C carrier. Verify access to the 36-pin cable and keep the blank Weight item open for confirmation. No statement about third-party compatibility or finished-camera protection should be inferred from the module data.
Use Contact Us to send the 4 MP/40× stream plan, host drawing and required serial functions. Ask for the missing Weight value separately.
