HD & IP CCTV Installation in Bangladesh
A CCTV system records video from cameras placed at gates, stores, production floors and perimeters so incidents can be reviewed and proven. HD analog cameras reuse coaxial cable and suit smaller or upgrade jobs. IP cameras give higher resolution, smarter analytics and easier expansion. The right choice depends on your site, cabling and how long footage must be kept.

Scope
What’s included.
Everything below is done by our own engineers and installation team, so one company answers for the result.
- Site walk and camera coverage plan on your layout
- Camera selection by view: detect, recognize or identify
- Cabling, conduit and weatherproof outdoor mounting

- As-built camera schedule and operator training
HD analog or IP cameras: which should you choose?
HD analog cameras send video over coaxial cable to a DVR. If your building already has coax from an older system, upgrading to HD analog keeps the cable and changes only the cameras and recorder. It is a sensible, low-disruption route for small shops, offices and phased upgrades where budgets are tight.
IP cameras send digital video over network cable to an NVR, usually powered through the same cable by PoE. They offer higher resolution, better low-light performance on many models and analytics such as line crossing and intrusion zones. Each copper network run is limited to about 100 meters, so large sites link buildings with fiber.
How many cameras does a factory need?
Count views, not cameras. Every camera should have a job: detect movement on a fence line, observe a loading bay, recognize people in a corridor or identify faces at the main gate. IEC 62676-4 describes these levels, and each one needs more pixels on the target than the last, which drives lens choice and mounting distance.
Typical priorities in a factory are the main gate, visitor reception, finished goods and fabric stores, loading bays, cash handling and perimeter walls. Buyer auditors often ask to see coverage of entries and exits and how long footage is kept, so we mark every camera and its purpose on your layout before any cable goes in.
How long can recordings be kept?
Retention depends on the number of cameras, resolution, frame rate, compression and whether cameras record all the time or only on motion. H.265 compression can cut storage needs considerably compared with H.264 at similar quality. We calculate storage from the number of days of footage you need, not the other way round.
Use surveillance-rated hard drives built for continuous writing, and protect the recorder with a UPS so a power cut does not corrupt footage. Where evidence matters, we can add a second recorder or an offsite copy of key cameras so one stolen or damaged recorder does not erase the record.
How it’s done
How we deliver it, step by step.
- 01
Coverage survey
We walk the site with you, mark each camera's purpose and check lighting, mounting points and cable routes.
- 02
Storage calculation
Camera count, resolution and retention days set the recorder and drive size before we quote.
- 03
Install and aim
Cameras, cabling and recorders are installed, and each view is adjusted on screen against its agreed purpose.
- 04
Night and playback check
We review every camera after dark and test playback, clip export and remote viewing.
- 05
Handover
You receive the camera schedule, passwords, network settings and training for guards and managers.
Price guide
What sets the price.
Every site is different, so we price from a survey, not a rate card. These are the factors that move the number, and the written quote shows each one.
- Number of cameras and the view each must deliver
- HD analog over existing coax or new IP cabling
- Recording days, resolution and frame rate, which set storage
- Cable distances, fiber links and outdoor mounting work
- Brand, analytics features and control room monitors
- UPS backup and network switch requirements

Frequently asked questions
Cost is driven by camera count, camera type, cable distances, how many days of footage you keep and whether existing coax can be reused. A small office and a factory campus are very different projects. After a site survey we give an itemized quote listing every camera, drive and switch, so nothing is hidden in a lump sum.
Yes. Both HD analog and IP recorders support the manufacturer's mobile app. We set up remote access with strong passwords, change default credentials and keep firmware current, because recorders exposed to the internet with factory settings are a common security weakness.
Only if it has backup power. We size a UPS for the recorder, switches and critical cameras, or connect the system to your generator-backed supply. Without backup, a power cut leaves a gap in recordings exactly when theft or trespass is more likely.
Usually yes. HD analog cameras and recorders often run on the existing coaxial cable, provided it is in fair condition. We test the cable runs first. Damaged or very long runs may need replacing, and we can mix in IP cameras where you want more detail.
Check daily that every camera shows an image and the recorder is writing. A professional service covering lenses, drives, focus, cables and firmware is commonly scheduled quarterly or twice a year. Factories with lint, dust and humidity usually need the more frequent schedule.
