10 Science Manual – Using Video Images for Fisheries Monitoring
3 Equipment
3.1 Housing
A dry and secure housing within close proximity of the site (cable runs greater than
250 metres should be avoided if possible) will be required for the recording
equipment.
For sites with no suitable equipment housing present, it will be necessary to install a
dry, secure cabinet to house the recording hardware, batteries (if used) and storage
media. Envico Engineering provides a range of glass reinforced polyester (GRP)
cabinets in all shapes and sizes suitable for this purpose (Figure 3.1). Contact
details are provided in Table . Alternatively, metal boxes may be preferable for sites
that are vulnerable to vandalism (Figure 3.1).
Figure 3.1: Examples of housing. The metal box houses a bank of three batteries
powering lighting and recording equipment in the green wall mounted cabinet. In the
second photograph is a GRP hut installed on a concrete base.
A video fish counting system has six major components:
• HOUSING
• POWER SUPPLY
• LIGHTING
• CAMERAS
• RECORDING HARDWARE
• IMAGE PROCESSING SOFTWARE
