   <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 (thanks to Majk for filling in details):</p>
   <list type="defn">
    <item term="Front door">
     <list type="1defn">
     <item term="Outer door">Two yale locks</item>
      <item term="Inner door">Motorised. Currently push-panel activated in both directions, or just from inside
   (locked from outside), or continuously open.  Entryphone provides audio, but
no longer video, to remote panels on 1st (kitchen) and 2nd (outside the meeting
room) floors as well as a handset by the front desk, all of which can unlock
the inner door temporarily</item>
     </list>
    </item>
    <item term="Upper Bow stair door">Not locked from inside, yale lock for
entry from the stair.  Will trigger intruder alarm if it's enabled.</item>
    <item term="Internal doors">
     <list type="1defn">
      <item term="Office">Yale lock</item>
      <item term="Kitchen">Yale lock</item>
      <item term="Various cupboards">Yale locks</item>
     </list>
    </item>
    <item term="Elevator">Currently can be turned off by a switch in the plant
room, not currently locked.</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>I've attempted estimates of cost below, but they are <emph>very</emph>
much under-informed by hard facts.  I found one quote from an installer, copied
below, but I think for what we want that's an under-estimate by at least a
factor of two.</p>
   <display>"The average starting cost for an access control security system is around £500-£800 per door. The average starting price for installing an access control system is around £300. A typical maintenance visit would cost you around £75-£125. It would cost you on average £92 to have your access control system repaired."</display>

   <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.
&#10;
"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>

    <title>[Failed to find another system I could match to our needs]</title>
    <p>I looked at approaching a dozen other websites, and they were all badly
designed, as well as being targeted at multi-tenant apartment buildings.</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>

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

   <title>Next steps</title>
   <p>Get a recommendation for an installer from Paxton's list, from Paradise
Green (the folks at AU), failing which go with S-S-S.</p>
   <p>Invite them around for a visit and discussion, leading to an RFQ.</p>
   <p>Get a quote from one other outfit at least (but maybe not yet?).</p>
