The CH-AHDVR8 MDVR is one of the CH-AHDVR4 and CH-AHDVR8 series Mobile Digital Video Recorders which are designed for use in commercial and industrial vehicles where constant recording from 5 to 8 cameras are required with HD video files saved to an onboard hard drive. The main DVR host has all the electrical connections and cable connections to the cameras and is housed in a metal, tamperproof enclosure with 2 key access, one for the outer enclosure which then provides access to the host itself and at this point only the SD Card can be removed. The second key also controls the main power to the DVR and also allows the hard drive to be removed and for this reason key control can be related to the level of access allowed with only approved personnel having the full access but still allowing limited access for maintenance and emergency files from the SD Card.
The CH-AHDRV8 units are in the same form factor as all our latest hard drive systems and normally uses a 1TB SSD with 2TB and 4TB SSD drives also available plus an SD Card up to 512GB is normally used with dual recording to both media available.
This enables recent files to be accessed from the SD card rather than removing the hard drive which can be simpler and also allows a higher level of security by having a key control scheme to prevent unauthorised shutdown of the DVR host.
Video output via either HDMI or CVBS is standard allowing the use of newer display technologies and customised programming to provide switchable views on an in-cab monitor.
The SwitchView system provides the ability to display chosen cameras to be shown full-screen when selected which can allow a rear facing camera to be setup as a normal reversing camera. Side view cameras can be linked to the indicators for improved visibility (in some conditions).
These are analogue input systems using either high definition AHD cameras or standard CVBS cameras although for full HD, higher resolution video files AHD cameras should be used as the systems can record at up to 1080P Full HD or 720P HD based on the cameras used. Note that CVBS camera will record at D1 only.
The CH-AHDVR8-2 is the base level model in the 8 channel range and allows only localised access to the video files, usually directly from the onboard storage which is typically a removable Solid State Drive (SSD) and/or SD card, both of which needs to be connected to a computer for review but as having direct access to the hard drive or SD Card is not always possible, an MDVR with wireless access may solve the problem.
Wi-Fi, 4G and Wi-Fi + 4G models allow either access via a browser on Wi-Fi using the DVR in Access Point mode or through a dedicated app and a cloud server platform using the 4G mobile network or Wi-Fi in Client mode when able to connect to a WLAN. Live streaming of video, remote download of saved files, streaming of previously saved videos, vehicle location on map and file download (PC only) are all available with visibility of all vehicles in the fleet which are connected to the system.
The CH-AHDVR8-4G is a mobile network connected device which can be connected to any Australian mobile data network using a data SIM and if required, Chipatronic can provide the SIM and service with data plan to access a national network.
In general high volume data plans are not required unless regular download of video is being carried out or extensive streaming of live video and the main use of this will be to access video files required as part of a compliance process, staff evaluation or incident investigation. All files which are remotely downloaded will remain on the hard drive in the normal manner until the standard video looping functionality deletes these when the drive is reaching maximum capacity to allow new files to be recorded and this will mainly depend on the drive capacity and the amount of time the vehicle is operating.
Usage of mobile data is the responsibility of the business and access to systems which may result in mobile data through file downloads or video streaming should be limited to users with sufficient training and knowledge of the implications.
The CH-AHDVR8-W is a Wi-Fi enabled device which has 2 modes; Access Point for device to device connection so using a smartphone or tablet you would connect to a Wi-Fi network generated by the DVR using a browser with the default device IP address or operating as a Client on an existing WLAN at the workplace the DVR can be accessed directly via DHCP allocated IP address and a browser or through the CMS cloud platform using browser or dedicated app.
The CH-AHDVR8-4GW combines both Wi-Fi and 4G and the DVR will connect through Wi-Fi where a recognised WLAN is available or 4G elsewhere (providing the required mobile network is available).
Please note that WLAN access requires the involvement of your IT team and they should be consulted prior to any deployment.
