Happy Halloween. 🎃 Forget ghosts. Here are the five things that actually frighten our engineers.

1. The fire alarm log book with one entry. From 2021.
2. The fire door wedged open with a fire extinguisher.
3. The camera that's been filming a wall since the bracket slipped in March.
4. The gate photocell with tape over it "because of the sun".
5. The door code. It's 1234. It's always 1234.

The good news? None of these need an exorcist. They need a service, a conversation, and occasionally a new code.

If any of these sound familiar, don't be scared. Just call.

Some people simply shouldn't get in.

Not everyone who walks up to your front door should be able to walk through it.

Good access control knows the difference. Staff in. Visitors logged. Leavers locked out the day they leave. And a full record of who opened what, and when.

No drama. No raised voices. The door just doesn't open.

Hawthorne Access Control. Designed, installed and looked after properly across the heart of Anglia.

Who you gonna call?

Strange noises in the building at 3am? Us, via your monitoring centre.
Door fobs refusing to work on a Monday morning? Us.
Fire panel flashing a fault nobody understands? Us.
Footage that looks like a paranormal investigation? Also us, though we'll fix the camera rather than the ghost.

We don't have a converted ambulance. We do have engineers across the heart of East Anglia who pick up the phone.

If it beeps, flashes or records, we're the ones to call.

The clocks go back on Sunday.

Which means, from Monday, most people will be leaving work in the dark, and most car parks, yards and side entrances will be in the dark too.

Three things worth ten minutes this week:

1. Check the night footage. Not the daytime footage. Walk the site after dark and see what the cameras actually see. If it's grey blobs, that's the moment to know, not after an incident.
2. Check the external lighting. Cameras need light, or they need to be the kind that doesn't. Dead bulbs and dark corners are where problems start.
3. Check the alarm set times. If staff are leaving later than the system expects, you'll get false alarms and grumpy phone calls.

Winter is when systems earn their keep. It's also when neglected ones get found out.

If you'd like us to do the after-dark walk with you, that's a normal request. We do a lot of them this time of year.

Emergency lighting. The one system in your building you only notice when it's not working.

1. It's a legal requirement in most non-domestic buildings. It's what gets people out when the power fails and the smoke comes in.
2. It usually needs to run for three hours on battery alone.
3. It needs a monthly function test and an annual three-hour drain test. That annual test is the one that finds the dead batteries.
4. The green running man was designed in Japan in the late 1970s by Yukio Ota, and adopted worldwide because nobody needs to read him.
5. A light glowing green on the wall isn't proof the battery will last three hours. Only the test proves that.

Good maintenance is rarely noticed until it matters.

Meet Eve. The engineers call her Steve. Nobody knows why 👀

We thought it was time you put some faces to the voices on the end of the phone.

Eve looks after admin, accounts and a fair bit of operations. If something needs sorting, she’s already on it. Whatever name she’s going by that day.

Simon is our client support and sales coordinator. He’s usually the first person you’ll speak to when you call, whether you need a quote, some technical advice or just a second opinion.

CCTV, fire alarms and access control only work as well as the people looking after them. These two are a big part of that.

Proud to support businesses across the heart of East Anglia.

We’re only ever a phone call away.

Five facts about intruder alarms. One of them involves spiders. 👀

1. The first electromagnetic burglar alarm was patented in 1853. Door opens, circuit closes, bell rings. Every alarm since is a variation on the theme.
2. Spiders genuinely cause false alarms. One wandering across a motion detector at 3am looks a lot like an intruder to the sensor. It's why we clean detectors at every service.
3. Police response isn't automatic. It needs a monitored system, an approved installer and police registration. A loud bell alone doesn't qualify.
4. Alarms are graded 1 to 4. Homes are usually Grade 2, commercial sites usually Grade 3. Your insurer may have a view.
5. A bell-only alarm relies on a neighbour caring. A monitored one relies on a signalling unit and a 24-hour centre. Only one of those is a plan.

If you can't remember your last service, or what grade you've got, we're happy to have a look.

Five facts about locks, doors and who gets in.

1. The oldest known lock is around 4,000 years old. Wooden, pin-based, and surprisingly close in principle to what's on your front door.
2. The modern pin tumbler lock was patented by Linus Yale Jr. in the 1860s. Still everywhere.
3. The most common PIN in the world is 1234. One analysis of millions of leaked codes found roughly one in ten people use it. Please don't be one in ten.
4. The plastic hotel keycard dates from the 1970s, invented by a Norwegian locksmith.
5. The most common way access control gets beaten isn't hacking. It's holding the door for a stranger because it felt rude not to.

Good access control is half technology, half habits. We can sort the first and help with the second.

"Trust, but verify."
Russian proverb

Made famous during the Cold War. Weirdly, it's the whole philosophy of access control.

You trust your team. Of course you do. But trust isn't a security system.

Verify means: the door knows who opened it and when. A lost fob can be cancelled in seconds rather than the locks being changed. Leavers stop being able to get in the day they leave, not when someone remembers.

None of that is about suspicion. It's about having answers when something goes missing, instead of a room full of people looking at each other.

Trust the people. Verify the doors.

Mission: Impossible. Ethan Hunt dangles from the ceiling of a vault that's protected by temperature sensors, sound sensors and a pressure-sensitive floor.

One drop of sweat from disaster.

In our experience, intruders are rarely that committed. They come through the fire exit someone propped open for a cigarette. They walk in behind a member of staff who held the door. They try the back gate that "sticks" and has done for a year.

Systems don't usually get beaten by athletes. They get beaten by habits.

The good news is habits are cheaper to fix than vaults. A site survey spots most of them in an afternoon.
