Account for Axis shock rearm and the new position baseline

Bottom line: Judge shock detection with its documented event interval and position behavior in mind, rather than expecting one alarm for every movement.

Source fact: documented behavior

The Shock detection API documentation says monitoring continues from the camera’s new position after an alarm.

To avoid multiple events for the same displacement, another shock event is not emitted until five seconds have passed.

The topic says high sensitivity can trigger alarms from very small displacements, including vibrations.

What the source does not establish

Do not treat this event as proof that the camera has returned to its accepted view. Keep event generation distinct from assessment of the image and physical installation. Confirm actual product support and the permitted commissioning method before moving equipment. Do not strike, loosen or forcibly shake an installed camera to demonstrate the documented alarm behavior.

Applicability questions

• Which physical change should trigger a response for this camera’s task?
• What normal vibration must the proposed test represent safely?
• How will the team identify the accepted view after a displacement?
• Does the receiving workflow mistakenly require a separate message for every closely spaced movement?

DSE recommendation: controlled next steps

The following steps are DSE recommendations based on the cited source.

DSE recommends an approved test-rig exercise that separates movement, emitted events and restoration of the intended view.

1. Use the manufacturer’s supported test approach on a noncritical unit or an approved fixture. Agree the permitted movements and observation method with the responsible technician. Save a reference view and identify the person who decides whether the final view is acceptable. Keep the exercise clear of active security coverage and structural or mounting work.
2. Prepare proposed movement cases separated by different observed intervals, including a pair within the documented event-suppression period. Record each input time independently of the received alert. Compare the receiver’s observations with the source’s event-timing rule. Do not count a deliberately suppressed repeat as proof that the sensor failed, and do not claim successful detection merely because one message arrived.
3. Review sensitivity with representative benign vibration on the approved rig. Compare unwanted alerts with the ability to identify the required physical change, using the same recorded inputs. After a displacement case, inspect the view and follow the supported restoration process. Require the operator to close the physical-view issue separately from acknowledging the shock event.

Verification and evidence

Keep device/software identity, supported test method, sensitivity setting, fixture description, input timestamps, received-event timestamps and before-and-after views. Record any interval where the expected event behavior needs manufacturer clarification. Distinguish event timing, physical state and operator response in the evidence record.

For the proposed response exercise, present an acknowledged alarm alongside a still-unacceptable view and ask the team to choose the next action. Use that case to verify the restoration handoff. These are proposed DSE tests; no camera was struck, displaced or tested and no detection performance is claimed.
