ARKIVE Digital Video Recorder
Product description
The Arkive system has principally been designed for use as an on-vehicle Digital Video Capture System capable of supporting multiple CCD cameras. It is particularly suited for use in Taxi's, Police vehicles, Busses, and Trains but can also be easily installed in fixed locations to provide the same facilities and protection.
ARKIVE captures images generated by CCD cameras and stores them for future use in the investigation of an incidents or accidents.
The system achieves this is through receiving the images generated by the cameras, processing them into a suitable format and storing them in non-volatile memory for latter retrieval.
When powered the system operates continuously, capturing images from each camera at set intervals, it can also be configured to capture images from cameras as a result of being triggered to do so, either by a contact closure or by receipt of a valid data string. As the received images are captured and formatted, they are also time stamped by the internal Real Time Clock and encoded to prevent un-authorized viewing of captured data.
In addition the system can be supplied with options for the capture of additional data such GPS location information, which may also be included in the data of each individual image captured and the ability to record the output of 2 microphones as audio files directly linked to the captured images.
The actual total number of images that may be stored is dependant upon the number and type of cameras (colour or monochrome), the required image quality and the required image rate, reducing or increasing the image quality, number of cameras, or frame rate, increases/decreases the number of frames which maybe stored accordingly.
In a standard configuration servicing 4 cameras at 1 second interval frame rate, set to 320 X 240 pixels, the system can store in excess of 2,500 images plus associated data from each of the 4 cameras. Total Images with 90 Meg 10,000 Standard
Images which are not specifically instructed to be held for latter download retrieval are automatically and continuously over written, with the oldest image being overwritten first.
At the occurrence of a significant event the device can be triggered to record and quarantine images from being overwritten, these images and associated data are held separately and securely until such time as the images are retrieved or cleared by an authorized person through the image download process.
Component items
Control Box
The Control box component part houses the main electronics and image storage components, this part along with the Installed base is usually located away from the operator, in the case of a vehicle installation the compact size of the device allows for a wide variety of location options.
Installed Base
The installed base is supplied with the Control box and allows all cabling of the device to terminated and tested without the Control box being present, in the event of a device failure the Control Box component can be easily swapped without the need to modify any cabling.
User Interface
The User Interface is a remote extension of the control box that provides input, output, status indicators and others signaling between the operator and the Control box.
Cameras
A range of colour and Monochrome cameras for internal and external use are available, some of which provide integral Infra Red illumination.

Principal features and benefits
Incident alarm activations.
In the event that an incident occurs, and the system is triggered by the operator into alarm mode, all subsequent images captured for the preset event duration are quarantined until such time as they are downloaded or the system is reset. In addition 250 images from each camera prior to the alarm activation are also appended to and locked into the quarantine file, this feature means that the events leading up to the moment the operator activating the system are also available to be examined at a latter time.
If the operator is under duress and unable to activate the incident alarm, the images of an incident still remain available until over-written, as an added security function holding down the alarm button for 5 seconds after the event has concluded locks the system and quarantines all of the images that have been recorded by the system up to that time.
These features ensure that the operator is always able to rely upon the system securely holding images in the event of an incident occurring.
Multiple alarm activations.
In general once the system has been activated into an alarm mode it must at some time after the activation have the images downloaded from it, or in the event of an accidental activation be reset.
Because ARKIVE provides vastly more image storage than other systems it offers the unique benefit of allowing the system to continue to operate after an accidental triggering of the alarm by providing multiple alarm activations.
At the time of alarm activation a preset number of images are recorded and held as a quarantined file, which will not be overwritten until a reset or download is performed. Additionally the status of the indicator LEDS on the user interface change state to display to the operator that an activation has occurred and that the system must be reset before the end of the shift. Despite the fact that the system has already quarantined a file of images, which cannot be overwritten, it continues to function normally and will respond to any other activation of the alarm during the remainder of the shift by storing and quarantining an additional files of images, this allows continued operation of the system until it is convenient to perform a reset or download.
Reach back on alarm activation
The Arkive system records continuously at the rate of 1 image per camera per (X) seconds, this is unlike other systems which record a few images when triggered by an event, and there after capture a single image each (X) seconds. Because the Arkive has many times the memory capacity of the other systems it is able to store thousands of images before it becomes necessary to over-write them, this affords a particular benefit when an incident occurs. It is often the case that by the time a operator becomes aware that an incident is underway and reacts by triggering the alarm much of the event may well have already occurred but not been recorded, the Arkive system resolves this by reaching back a preset number of frames prior to the incident occurring and adding these to quarantined file of the event in progress.
Continuous recording provides the additional benefit of not requiring the camera system to be connected to external triggers such as brake pedal, doors, taxi meters etc as the system is always and continuously capturing images at the highest rate, and because there are fewer connections system reliability is improved and installation and maintenance times are reduced.
Suspicion mode
The Arkive system is provided with an additional activation button, which triggers the device to capture a pre-set finite number of images into one of two files for latter download if required. Called suspicion mode this facility enables an operator to record an activity of which he is suspicious but which has not yet developed into an incident which requires the use of the incident alarm. Each subsequent pressing of the suspicion button captures a fresh series of images alternating them between the two file locations.
System installation
ARKIVES low operating power requirements mean that it is not necessary to switch the device off in order to conserve vehicle battery power. The benefit of this is that the system remains on whenever the vehicle is powered removing the risk that the operator will inadvertently fail to switch the system on and therefore be operating without the protection of the camera system.
New technology
As the most recently designed camera system available Arkive offers the benefits of the most up to date technology, of particular importance are the features of continuous high capture rates, significantly larger image storage capacity and very high speed downloading of captured images. Additionally the system has been designed with enhanced security features such as tamperproof fixings, security seals and activity logging which records an array of operational data. The system also has the ability to transmit images via a radio modem and can be remotely reset after an inadvertent triggering from a host base when connected to a modem.
