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

39 <p>Recommended by the team at Augustine United: "the Paxton Net2 system [is]
40 very popular and something of a market leader".</p>
41 <p>Two relevant devices: A standard entry-panel and a door-latch.</p>
42 <p>Both are activated by a proximity card or fob, and both can be installed
43 for standalone use, with a master card used to
44 enable access cards, or as part of a network-controlled system for much more sophisticated usage patterns.</p>
45 <display>Staff and visitors are issued with electronic tokens instead of
46 keys. User tokens can be added to the system in seconds by presenting an enrolment card to the door/entry-panel.
47
48 If someone loses their token, it can be simply barred from the system by presenting a shadow card to a reader.</display>
49 <p>The entry-panel version would be the candidate for the front door,
50 replacing the existing panel.</p>
51 <p>The standalone system has three components: the entry panel, the
52 monitor(s) and the controller. I <emph>assume</emph> multiple monitors can be
53 used. It's not easy to find prices, but I am pretty confident that the parts
54 we need should be available for between £1000&ndash;2000. Installation would
55 be at least a person-day, I would guess, so could easily be £500 or more.</p>
56 <p>Upgrading to the next level, with full (PC and mobile app) software-based control of
57 token-holders, remote management, etc. would probably be as much again.</p>
58 <p>I <emph>think</emph> that only a further upgrade, and replacement of the
59 door panel, would get us to mobile-as-keycard functionality.</p>
