1 – 4 channel AHD MDVR for trucks, buses, mining
The CH-AHDVR4 series is the latest evolution of our most popular DVR for heavy vehicles where recording from 1 to 4 cameras is required.
The main feature of these devices is they are now a hybrid device which can work with both traditional CVBS cameras and also use newer and higher resolution AHD cameras, offering improved video recording while retaining the ease of use and practicality of the older, CVBS only systems.
As standard, a DVR system would be supplied with AHD cameras as these are 720P or 1080P HD but an existing DVR can be replaced with this model and retain the original cameras if that is preferred.
These recording systems can be supplied with a 500GB or 1TB solid state hard drive (SSD) as standard which provides greater durability in more arduous situations. A 1TB drive will store approximately 500 hours of high-quality video from 4 cameras, with or without audio and an SD card can be added to provide a level of redundancy as recording will fail over to this should a problem occur with the main hard drive.
With two USB ports, one can be used to connect a standard mouse which is used to access the system menu if needed and the front port can be used with a USB disk to copy files onto.
These systems use standard Chipatronic cabling systems and any of our Real Image cameras including internal models with audio input (both AHD and CVBS types are available).
For common camera options, see here.
Up to 3 external alarm inputs can be configured and linked to video channels to provide a separate record of events related to the alarm input or the alarm function can be set up to switch the video output to show specific cameras which can be configured in the same way as a reversing camera.
These models have a traditional CVBS video output for use with standard vehicle monitors and also a HDMI socket output for higher quality video.
7″ and 10.1″ LCD monitors with HDMI input are available for use with the DVRs where high quality vision is required.
Chipatronic also stocks handheld, battery powered test monitors with HDMI input which should be used for basic checks and camera setup.
Options can include GPS for speed and location and an external button for dash mounted indication of the system status, Start/Stop control of the video recording or as an emergency alarm input for the driver.
Wireless connectivity via the 4G network can be provided (see CH-AHDVR4-4G) which allows real-time access to video from the vehicle, download of saved video files, location via map with alarm notification also able to be linked to video.
The DVR is supplied in a lockable, metal enclosure for tamper-proof installation and can be installed by an auto-electrician or similarly skilled worker with just 3 wires required for power: battery, ignition, ground. All other connections are by standard cables with power to the cameras supplied through the DVR host.
