THB — The House of Business THB Security SolutionA division of THB — The House of Business

Security systems that still work the day you need them.

CCTV, access control, attendance, intruder alarm, fire detection, intercom and vehicle tracking — designed against your actual layout, installed properly, documented, and kept running under a maintenance schedule.

Field device camera, sensor, reader Recorder or panel NVR, controller, alarm panel recording / alert / fault Network and power PoE switch, UPS backup Your screen phone, desk, control room scheduled service goes back down the line — before it fails, not after

Every system we install is some version of this line: a device that sees, something that records or decides, a network and power path that must not drop, and a screen where you actually look. Most failures happen in the middle two, which is where nobody inspects.

Designed after a survey

Camera positions and device counts come from your layout, not from a package.

Brands serviceable in Dhaka

Makes whose spares and service you can get locally.

The passwords are yours

Device passwords, app accounts and the as-installed layout are handed over.

Maintained, not just installed

Scheduled health checks catch the dead camera before the day you need the footage.

What we usually get called for

If any of these sound like your premises, a survey is the cheapest next step.

What we do

Twelve systems, supplied and serviced by one team.

CCTV cameras

Cameras chosen for the light and distance at each position, not one model repeated everywhere.

Recorders and storage

Recorder and drive sizing done from channel count, resolution and the days you need to look back.

Remote viewing and alerts

Accounts in your name, playback that works from outside, alerts tuned so they mean something.

Access control

Readers, locks, exit buttons and emergency release, so each door opens only for the right people.

Time attendance

Configured against your shift pattern, exporting in a form payroll can use.

Turnstiles, barriers and auto gates

Wired into the same access system, so one card works at the gate and at the door.

Intruder alarm and sensors

Zoned panels, so a real alarm tells you which part of the building it came from.

Fire detection and alarm

Panels, detectors and call points zoned to the layout and tested on a schedule with a signed record.

Fire extinguishing equipment

Supplied, mounted with signage, refilled before expiry and logged.

Video door phone and intercom

Door stations, indoor monitors and lock release, so the resident sees before opening anything.

Smart locks and home security

One app, with the owner as the only administrator.

Vehicle tracking devices

Live location, geo-fence alerts, fuel monitoring and remote engine cut-off on confirmed theft.

Technical limits we work within

These are the numbers that decide whether a system works.

Camera resolution

2MP shows that a person passed; 4–8MP is what recognises a face or a number plate.

Recording retention

Quoted in days, not terabytes: 15 common, 30 sensible, 90 for disputes and claims.

Cable runs

About 90 m on network cable with PoE; beyond that, a switch, extender or fibre.

Night vision range

Plan for roughly half the figure on the box in real dust and rain.

Power backup

Sized to cover recorder, switch and cameras together, with the runtime stated.

Access control capacity

Matched to your headcount with room to grow, so old records are not deleted.

Alarm and fire zoning

Zoned by floor or area, so the panel names the place.

Warranty

One year on our workmanship; equipment warranty registered in your name.

What you receive at handover

A system is finished when you can operate it without us.

The design

Prepared before any equipment is bought.

  • Camera position and coverage plan
  • Device list with make, model and quantity
  • Retention and storage calculation
  • Cable route and power point requirement
  • Written quotation, itemised with VAT

The installation

The part that decides whether the system lasts two years or ten.

  • Concealed or casing cable work, tied and routed
  • Every cable and port labelled at both ends
  • Weatherproof junctions on outdoor runs
  • Earthing and surge protection where needed
  • UPS or IPS backup connected and tested

The configuration

Set up for how your premises actually runs.

  • Recording schedule, motion zones and retention set
  • Mobile and desktop access tested from outside
  • Users, shifts and door rights entered
  • Alarm zones and sensitivity tuned

Where we install

The design follows the premises.

Garments and textile factories Corporate and head offices Banks, NBFIs and MFS agents Apartments and housing societies Private homes and duplexes Hospitals and diagnostic centres Schools, colleges and universities Malls, showrooms and retail Warehouses and distribution hubs Construction and project sites Hotels, resorts and restaurants Cold storage and food processing Solar plants and power installations NGOs, embassies and project offices Vehicle fleets

How a job runs

Nothing is quoted before we have walked the premises.

01

Survey

We check the night light, the power points, the cable routes, and what has already gone wrong.

02

Design and quotation

Coverage plan and itemised device list within 48 hours.

03

Installation

Done around your working hours, weatherproofed outdoors, labelled as it goes in.

04

Commissioning and handover

Tested, passwords changed to yours, staff trained, documents handed over.

05

Maintenance

Scheduled visits with lens cleaning, channel checks, backup and disk health, and a signed report.

Four ways to work with us

Every quotation follows the free survey.

Supply and installation

One-time project

  • Design, equipment, cabling and commissioning
  • Make, model and warranty stated in the quotation
  • One year on our workmanship and wiring
  • Documents and passwords handed over
  • Staff training included

Annual maintenance

AMC, yearly

  • Scheduled visits with a signed service report
  • Service call attended within 24 hours
  • Lens cleaning, channel and backup testing
  • Hard disk health watched before it fails
  • Priority on spares and replacement

Takeover and repair

For a system someone else installed

  • Inspection of cameras, recorder, cabling and power
  • Written condition report before any spending
  • Password recovery or controlled reset
  • Repair and upgrade without replacing everything
  • Continued under AMC afterwards

Design and consultancy

Independent of supply

  • Coverage and device plan for your building
  • Specification a third party can tender against
  • Review of a quotation you already have
  • Documentation for buyer or insurer audit
  • No obligation to buy equipment from us

Terms you will see in a quotation

Security quotations are full of words that hide what is actually being sold.

IP vs analogue

IP scales better; HD analogue reuses existing coax. Mixing them badly is the problem.

PoE

One cable carries data and power, so the switch must be sized correctly.

Retention

Ask for it in days. A quotation listing only terabytes is hiding the answer.

WDR and low light

Lets one frame handle a bright doorway and a dark interior at once.

IP rating

The dust and water rating — stated, not assumed, for anything mounted outdoors.

False alarm

Enough of them and the real alarm gets ignored — that is the actual danger.

AMC

Scheduled servicing and a promised response time, not a call after failure.

Geo-fence

A boundary on the map that alerts you when the vehicle leaves it.

Questions clients ask first

How many cameras do I actually need?

Usually fewer than a quotation suggests, and placed differently. The survey gives you a coverage plan.

How many days of footage should I keep?

Thirty days for most offices; ninety where a dispute could surface late.

Will it keep recording during load-shedding?

Only if the backup covers recorder, switch and cameras together. A UPS on the recorder alone records a black screen.

Can you repair a system another company installed?

Yes. You get a written condition report before spending anything.

Which brand do you use?

Whichever suits the position and is serviceable locally. We quote by make and model.

Who holds the passwords afterwards?

You do — handed over in writing at completion.

How fast do you respond when something stops?

Within 24 hours under an AMC; many faults are solved on the phone the same hour.

Do you work outside Dhaka?

Yes, nationwide, with a realistic maintenance schedule for distant sites.

System down, or footage needed urgently?

Call and describe what you are seeing on the screen. It is often solved on the phone before anyone travels.
