STACK produce a Solid-State Digital Video Recorder, and the customer base for these units is quite impressive (although confidentiality agreements don't permit me to shout about who they are). The first version developed 4 years ago cost £3,600 but in 2009 a DVR2 range was launched with the DVR Clubman priced at £699. Please note that this does not include the bullet camera or Compact Flash card (cheaper to buy this from Jessops then from STACK). For those interested, you can also turn the DVR into a video-logger.
