The NH16 has 4TB primary storage (expandable to 8TB), and 512GB backup storage (expandable to 1TB).

Protected Alarm is a feature available on the NH16 that allows a portion of storage media to be reserved for alarm data (video, audio, and associated telemetry flagged by an event).

Normally, when storage media becomes full, the recorder overwrites the oldest data (including alarm data) with new recordings. If a Protected Alarm is specified, alarm data is preserved and not overwritten by non-alarm recordings until it has been stored for longer than a set period of time (user defined)

The NH16 has 2 featured IP cameras that are available at launch (C3Q9PD and C3Q9PD)

For customers migrating from a previous generation NVR or DVR, the NH16 is fully compatible with our existing line of legacy IP, AHD, and Analog cameras. 

The NH16 supports up to 8 monitored inputs which are broken down as follows.

• 5 Signal Inputs (Signals 1 to 5)
• 2 Alarm Inputs (Alarm 1 & Alarm 2)
• 1 Wake Input (mappable as Signal 6)

These are special inputs designed to monitor a voltage level on the vehicle.  Voltage levels may be high or low.  For example, a brake voltage might be 0V when brakes are not active and above 5V when they are active.  Alternately, a door position switch might be above 5V when the door is closed and 0V when the door is open.  In each case, the voltage is either low (0V) or high (above 5V) and the signal input detects these levels.

Signal inputs must be programmed to react to a monitored voltage that is Low or High.  To have a signal react to a low voltage, set the Signal Level as “Active L” (Low).  Conversely, to have a signal react to a high voltage, set the Signal Level as “Active H” (High).  In each case, the signal will be seen by the DVR as “Active” when the monitored voltage is high or low, as programmed.

Alarm inputs are general purpose inputs designed to monitor a dry contact (contact without a voltage).  Monitored dry contacts may be N.O. (Normally Open) or N.C (Normally Closed).  An example of a N.O input might be a contact on a wheelchair ramp deployment system that is Open when the ramp is in storage mode but transitions to Closed when the ramp is deployed.  Alternately, a Driver Duress Button is often Closed under normal conditions and transitions to Open while the driver presses the button. 

NOTE:

Alarm inputs are Edge Triggered.  This means the input must transition from the selected “Normal State” to alternate “Activation State”.  Using the Driver Button as an example, the button must transition from not pressed to pressed for the DVR to see the input as active; the transition from pressed to not pressed is ignored.  Using the wheelchair ramp as another example, the ramp must transition from storage mode to deployed for the DVR to see the input as active; the transition from deployed to storage mode is ignored.

Wake is a special input used to start the DVR without engaging the vehicle ignition.  The DVR reacts and functions as if the ignition input was triggered but startup reason is recorded to event and system logs as Wake instead of ignition.  A common use of the Wake input is to start the recorder whenever a vehicle occupancy sensor sees a person onboard the vehicle.

If the Wake function is not needed, the DVR may be configured to disable function and instead trigger the logical input “Signal 6”.  When configured this way, the Wake input becomes a 6^th signal input.  This may be of use if a systems deployment requiring an extra input.

NOTE: 

Wake input is physically limited to support an Active High input only. A voltage above 5v is required for activation of either the Wake or Signal function.
