Introduction</h2><p>I've had a quick look at the technology available to provide more | |
112 flexible access control into and within 7VT.</p><p>Per our previous discussion, it's worth distinguishing at least four | |
113 types of access we might consider (thanks to Majk for filling in details):</p><dl class=" "><dt><b><a name="Front_door">Front door</a></b></dt><dd> | |
114 <ul class="naked "><li><a name="Outer_door"><b>Outer door</b></a> | |
115   Two yale locks</li><li><a name="Inner_door"><b>Inner door</b></a> | |
116   Motorised. Currently push-panel activated in both directions, or just from inside | |
117 (locked from outside), or continuously open. Entryphone provides audio, but | |
118 no longer video, to remote panels on 1st (kitchen) and 2nd (outside the meeting | |
119 room) floors as well as a handset by the front desk, all of which can unlock | |
120 the inner door temporarily</li></ul> | |
121 </dd><dt><b><a name="Upper_Bow_stair_door">Upper Bow stair door</a></b></dt><dd>Not locked from inside, yale lock for | |
122 entry from the stair. Will trigger intruder alarm if it's enabled.</dd><dt><b><a name="Internal_doors">Internal doors</a></b></dt><dd> | |
123 <ul class="naked "><li><a name="Office"><b>Office</b></a> | |
124   Yale lock</li><li><a name="Kitchen"><b>Kitchen</b></a> | |
125   Yale lock</li><li><a name="Various_cupboards"><b>Various cupboards</b></a> | |
126   Yale locks</li></ul> | |
127 </dd><dt><b><a name="Elevator">Elevator</a></b></dt><dd>Currently can be turned off by a switch in the plant | |
128 room, not currently locked.</dd></dl><p>(I've assumed we won't change the exit-only emergency nature of the | |
129 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 | |
130 homeowners or businesses. Some of the business-orientated ones at least | |
131 mention small businesses, which is probably the closest we're going to get for | |
132 our needs.</p><p>Below are summaries of the offerings from a few of the companies I've | |
133 looked at. We would not deal directly with any of them, but would need to | |
134 contract with a local specialist firm for installation. I presume we've got | |
135 someone on the books for maintainance of the current entryphone/door-opener | |
136 etc., but we may need a different outfit for a new system.</p><p>I've attempted estimates of cost below, but they are <i>very</i> | |
137 much under-informed by hard facts. I found one quote from an installer, copied | |
138 below, but I think for what we want that's an under-estimate by at least a | |
139 factor of two.</p><blockquote class="vanilla"><div>"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."</div></blockquote></div><div><h2>2. Manufacturers</h2><div><h4>2.1. <a href="https://www.paxton-access.com/">Paxton</a></h4><p>Recommended by the team at Augustine United: "the Paxton Net2 system [is] | |
140 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 | |
141 for standalone use, with a master card used to | |
142 enable access cards, or as part of a network-controlled system for much more sophisticated usage patterns.</p><blockquote class="vanilla"><div>"Staff and visitors are issued with electronic tokens instead of | |
143 keys. User tokens can be added to the system in seconds by presenting an enrolment card to the door/entry-panel. | |
144 | |
145 | |
146 "If someone loses their token, it can be simply barred from the system by presenting a shadow card to a reader."</div></blockquote><p>The entry-panel version would be the candidate for the front door, | |
147 replacing the existing panel.</p><p>The standalone system has three components: the entry panel, the | |
148 monitor(s) and the controller. I <i>assume</i> multiple monitors can be | |
149 used. It's not easy to find prices, but I am pretty confident that the parts | |
150 we need should be available for between £1000–2000. Installation would | |
151 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 | |
152 token-holders, remote management, etc. would probably be as much again.</p><p>I <i>think</i> that only a further upgrade, and replacement of the | |
153 door panel, would get us to mobile-as-keycard functionality.</p></div><div><h4>2.2. [Failed to find another system I could match to our needs]</h4><p>I looked at approaching a dozen other websites, and they were all badly | |
154 designed, as well as being targeted at multi-tenant apartment buildings.</p></div></div><div><h2>3. Local installers</h2><div><h4>3.1. <a href="https://www.edengroup.co.uk/access-control/">Eden Group</a></h4><p>List Paxton as a brand they supply, "Paxton Gold" supplier. 25 mostly good Google | |
155 reviews, mostly aerials rather than security, | |
156 individuals not corporate...</p></div><div id="sss"><h4>3.2. <a name="sss"><a href="https://www.safesimplesecure.com/">Safe Simple | |
157 Secure</a> (S-S-S)</a></h4><p>"Paxton Gold" supplier, security only, 125 Google reviews, 5-star | |
158 overall, at least one regarding commercial premises.</p></div></div><div><h2>4. Next steps</h2><p>Get a recommendation for an installer from Paxton's list, from Paradise | |
159 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></div></div></body></html> |
