Support that stays
with your system
Buying the hardware is the easy part. CSL Systems installs it, configures it, maintains it and repairs it — with trained engineers and genuine spare parts, anywhere in Bangladesh.
From first install to year-round upkeep
Six services that cover the whole life of a security, attendance or networking system. Every one is delivered by our own engineers — not subcontracted away after the sale.
Professional installation and commissioning
We bought the cameras from someone else and the installer never came back. We want it done properly this time.
An installation is only finished when the system actually works the way it was designed to. Our engineers survey the site, run the cabling, mount and align every device, then test and document the result before handover — so nothing is left for you to discover later.
- Free site survey and device placement plan
- Structured cabling, trunking and rack dressing
- Camera focus, angle and coverage verification
- Door controller, lock and exit device wiring
- Network configuration and remote-view setup
- Handover with as-built documentation
System setup, integration and staff training
The machine is on the wall but nobody here knows how to pull a payroll report from it.
Hardware without configuration is just hardware. We enrol your users, build the shift rules, set the access levels and connect the system to the software you actually use — then train your team until they can run it without calling us.
- User enrolment: fingerprint, face, card and PIN
- Shift, roster and overtime rule configuration
- Access levels, time zones and door groups
- Payroll and HR software integration
- Mobile and remote-viewing app setup
- Hands-on training for your admin staff
Annual Maintenance Contracts with fixed costs
Every breakdown turns into a new quotation and a new negotiation. We want one predictable yearly cost.
An AMC turns unpredictable repair bills into a single planned budget line. You get scheduled preventive visits, priority response when something does fail, and labour covered for the whole term — so a dead camera on a Sunday is not a procurement exercise.
- Scheduled preventive visits through the year
- Priority response ahead of non-contract calls
- Labour and service charges covered
- Comprehensive option including spare parts
- Health reports after every scheduled visit
- Single yearly cost, agreed up front
Planned servicing that prevents the failure
We only found out half the cameras had stopped recording when we needed the footage.
Most system failures announce themselves long before they matter — a failing hard disk, a lens fogging over, a battery near end of life. Scheduled maintenance catches those early, so you are not discovering problems on the day you need the evidence.
- Camera cleaning, refocus and angle correction
- Recorder health, disk status and retention audit
- Backup power and battery replacement checks
- Firmware and software version updates
- Cable, connector and termination inspection
- Written report with any risks flagged
Diagnosis and repair with genuine spares
The local technician replaced a part and it failed again in two months. We want the real component.
As an authorized channel partner we source genuine replacement parts through official channels, so a repair restores the device instead of postponing the failure. Where a unit is beyond economical repair we say so plainly and quote the replacement.
- Fault diagnosis at your site or in our workshop
- Genuine spare parts through authorized channels
- Board-level repair where it is viable
- Warranty claim handling with the manufacturer
- Loan units on request during longer repairs
- Honest replace-or-repair recommendation
A real support desk you can actually reach
When something stops working we just need someone who picks up and knows our system.
Most issues never need a site visit. Our support desk takes the call, connects remotely where possible and resolves it the same working day — and when an engineer is genuinely needed, we dispatch one instead of passing you to a queue.
- Phone and WhatsApp support, Sat–Thu 9AM–7PM
- Remote diagnosis and configuration assistance
- Same-working-day response on support calls
- Escalation to an on-site engineer when needed
- Guidance on software, apps and remote viewing
- Nationwide coverage across Bangladesh
Support is the part most suppliers skip
Anyone can sell you a box. What decides whether the system is still working in three years is what happens after the invoice is paid.
