I am pretty sure the last part of that is some sort of typo or accidentally included text (it sort of looks like something from a network DVR for security cameras). The MX104-PREM-AC-BNDL is:
MX104-premium bundle, 4 MIC slots, 2 PS, 2 Res SW licenses included: JUNOS
Meaning you can use all 4 MIC slots, it has 2 power-supplies, two routing-engines, and includes the JunOS software license. You would still need to purchase licenses to use the built-in 10-gig ports, or to use any of the usually licensed services (Jflow, VPN, CGNAT, Stateful FW, advanced-routing, etc.).
Most of the online resellers use automated tools to parse the pricelist and generate a catalog, so likely just an error on a pricelist somewhere.
