Door Access for Katy Businesses, From One Door to Fifty

Pick the size of system before you pick a brand

Three kinds of system cover nearly every small and mid-size business. The right one depends on how many doors you have, how many people come and go, and who will manage the user list.

For most Katy businesses with more than two doors the real choice is between the second and third rows. Both put a wired controller behind the doors; the difference is where the software lives and how you pay for it. Also ask about lock-in. Some platforms run on controller hardware that several software vendors support, which leaves a way out later. Others only work with their own readers and panels, so leaving means replacing hardware.

What your staff should carry to get in

• 125 kHz proximity cards and fobs. Cheap and everywhere, and copied in seconds with an inexpensive handheld device. Plenty of Katy offices still run them from an original install. They are acceptable on low-risk interior doors; we do not recommend them for a new perimeter.
• Encrypted 13.56 MHz smart cards. A modest step up in cost, much harder to clone, and printable as a photo ID badge.
• Mobile credentials. The phone becomes the key, by Bluetooth from a pocket or by a tap. Nothing to lose or collect back, and issuing one is an email. Keep a few cards on hand for staff who would rather not put a work credential on a personal phone.
• PIN codes. Useful as a second factor on a server room or pharmacy, weak as the only factor, because codes spread.

Timing access control in a new Katy finish-out

A lot of commercial space in Katy’s newer centers is delivered as a shell: slab, demising walls, a storefront and a rear door. The finish-out is the cheapest moment to add door access and the easiest one to miss.

1. Get it on the door hardware schedule. The architect’s hardware schedule has to show electrified hardware before doors and frames are ordered. A frame that arrives without a strike prep, or a door without a hinge prep for power, means field cutting later.
2. Blocking and boxes. Backing in the stud wall for each reader at the right height, and a box for the exit push button where one is needed.
3. A pathway to one room. A clear ceiling route or conduit from every door to the room where the controller will live, usually the IT or electrical closet.
4. Dedicated power. A 120-volt circuit for the access power supply, installed by the electrician and not shared with the break room.
5. Sequence with the GC. Our cable goes in and gets tested before drywall closes, and trim-out happens after paint, so we coordinate visits with the general contractor’s schedule.

If the walls are already closed, access control is still very doable. It takes more labor and more care, which is the retrofit case further down.

What common Katy businesses ask for

Daycares and learning centers

Parents need to get in at drop-off and pickup, and not in the middle of the afternoon. Many centers give each family a code or card that works only during those windows, keep the front door on a staff release button the rest of the day, and want a single command that relocks every exterior door. Free exit from inside remains in place at all times.

Fitness studios with unstaffed hours

A member credential that stops working the moment a membership lapses, plus a camera on the entry so one badge followed by three people is visible after the fact. If the membership software can talk to the access platform, suspended accounts lock out automatically; if it cannot, somebody has to do it by hand, and that step gets forgotten.

Churches

Doors that unlock on a schedule for services and relock afterward, separate credentials for staff, volunteers and outside groups renting the hall, and a children’s wing with tighter rules than the sanctuary.

Medical and dental offices

A front door that follows office hours, a staff entrance from the back lot, and supply or medication rooms limited to one group. Cleaning crews get a schedule that ends when their shift does.

Flex and light industrial

A reader at the office entry, a fail-secure strike on the rear man-door, and roll-up door operators that respond only to authorized staff.

Adding readers to a suite you already occupy

In an existing strip-center or office-park suite, the front is usually an aluminum and glass storefront door and the back is a steel door facing the service lane. The back door often matters most. It is out of sight, deliveries prop it open, and it is where employees actually come and go. A fail-secure strike, a door position switch that reports the door when it is propped, and a camera watching it cover most of that risk.

Cable typically runs through the drop ceiling and down inside the wall beside the frame, and the controller mounts in a closet or beside the network rack. We keep each door’s downtime to a few hours so the business stays open. Storefront doors take strikes made for narrow aluminum frames, so we look at the existing latch before choosing anything.

Katy sun, wind-driven rain and high water

• Afternoon sun. West-facing storefronts bake readers and keypads well past what some indoor-rated models tolerate. We specify outdoor-rated readers and, where the layout allows, mount them under an overhang.
• Rain. Wind-driven rain works its way behind surface-mounted readers. A sealed box and a drip loop in the cable keep water out of the wall cavity.
• Flood height. In parts of the Katy area that took water during Harvey, owners now ask for controllers, power supplies and batteries to be mounted well up the wall, never on the floor. Done at install time, it costs almost nothing extra.

What happens when we come out

EVOTECH is based in Katy, so visits here are usually a short drive. On site we walk every door with whoever manages the space, note the door and frame material, the existing hardware and the swing, and find a location for the controller. Then we ask how the day actually runs: who opens, who closes, who comes in on weekends, which rooms only some people should enter. From that we write an itemized quote, door by door, naming the system size and credential we recommend and why.

Things that change the price

• Number of doors, and whether each one needs new electrified hardware or only a reader
• Open framing during a finish-out versus finished walls
• Credential type and quantity
• Cloud subscription versus on-site software
• Roll-up door or gate integration
• Linking door events to cameras
• Whether an existing system’s cable and hardware can be reused
