The garden also has various CCTV cameras from
Henrys CCTV Centre,
most with built-in infra red illumination for night vision,
that feed into a multi-channel digital video recorder. The main DVR that runs 24/7 is a Hikvision DS8008 with locally written PC
client software, the main screen is as below, showing eight cameras live, and allowing retrieval of movies and stills. The DVR
can stream all these images over the internet, but the bandwidth needed is horrible. Henry's also sells a range of DVRs.
