   <title>Introduction</title>
   <p>I've had a quick look at the technology available to provide more
flexible access control into and within 7VT.</p>
   <p>Per our previous discussion, it's worth distinguishing at least four
types of access we might consider:</p>
   <list type="defn">
    <item term="Front door">Motorised.  Currently push-panel activated in both directions.
Entryphone provides audio but not video to remote panels on 1st and 2nd floors,
which can (unlock/open?).</item>
    <item term="Upper Bow stair door"></item>
    <item term="Internal doors"></item>
    <item term="Elevator"></item>
   </list>
   <p>(I've assumed we won't change the exit-only emergency nature of the
double-doors at the bottom of the main staircase.)</p>
   <p>Most of the companies whose websites I've looked at are aimed at either
homeowners or businesses.  Some of the business-orientated ones at least
mention small businesses, which is probably the closest we're going to get for
our needs.</p>
   <p>Below are summaries of the offerings from a few of the companies I've
looked at.  We would not deal directly with any of them, but would need to
contract with a local specialist firm for installation.  I presume we've got
someone on the books for maintainance of the current entryphone/door-opener
etc., but we may need a different outfit for a new system.</p>

   <p>Recommended by the team at Augustine United: "the Paxton Net2 system [is]
very popular and something of a market leader".</p>
   <p>Two relevant devices:  A standard entry-panel and a door-latch.</p>
   <p>Both are activated by a proximity card or fob, and both can be installed
for standalone use, with a master card used to
enable access cards, or as part of a network-controlled system for much more sophisticated usage patterns.</p>
   <display>Staff and visitors are issued with electronic tokens instead of
keys.  User tokens can be added to the system in seconds by presenting an enrolment card to the door/entry-panel.

If someone loses their token, it can be simply barred from the system by presenting a shadow card to a reader.</display>
   <p>The entry-panel version would be the candidate for the front door,
replacing the existing panel.</p>
   <p>The standalone system has three components: the entry panel, the
monitor(s) and the controller.  I <emph>assume</emph> multiple monitors can be
used.  It's not easy to find prices, but I am pretty confident that the parts
we need should be available for between £1000&ndash;2000.  Installation would
be at least a person-day, I would guess, so could easily be £500 or more.</p>
   <p>Upgrading to the next level, with full (PC and mobile app) software-based control of
token-holders, remote management, etc. would probably be as much again.</p>
   <p>I <emph>think</emph> that only a further upgrade, and replacement of the
door panel, would get us to mobile-as-keycard functionality.</p>

    <p>List Paxton as a brand they supply, "Paxton Gold" supplier.  25 mostly good Google
reviews, mostly aerials rather than security,
individuals not corporate...</p>

    <p>"Paxton Gold" supplier, security only, 125 Google reviews, 5-star
overall, at least one regarding commercial premises.</p>
