Camera-event selection

Camera-event references

The document names VCA events and configurable camera features including heat map, ANPR and people counting. Confirm the exact camera, firmware and required function; do not assume recorder-native AI or included licenses.

Selection notes

• Shared reference applies only to the three complete bare models printed in this DS-7700NI-K4 family document; confirm the actual supplied unit and firmware.
• Use only the DS-7732NI-K4 column and its explicitly merged cells; confirm the complete model label and firmware.
• Camera inputs, remote connections, output timings, synchronous playback and decoding are different limits. Decoding modes are separate and are not summed.
• The optional /ALARM 16+9 configuration is a separate ordering choice, not the assumed bare-model package. It does not add a confirmed Ctrl12V output to this reference.
• Confirm exact HDD compatibility, retention needs and firmware. No installed drives, PoE camera ports, RAID capability, stock, price, delivery or local warranty are promised.
