Choosing CCTV and surveillance equipment in Bangladesh
Planning a dependable surveillance deployment for a commercial facility, distribution depot, corporate office or retail premises in Bangladesh requires matching camera hardware to physical site conditions. Shelly International supplies the equipment needed for small branch setups up to multi-building monitoring centres, covering IP network cameras, high-definition analogue equipment, standalone recorders, PTZ domes, dash cameras, and unified alarm or video intercom setups.
Selecting security hardware involves balancing coverage angles, night-time illumination, transmission medium, and retention requirements. Analogue HD systems offer straightforward coaxial cabling for budget-conscious retrofits, whereas modern IP camera platforms run over standard structured networking cables with Power over Ethernet (PoE), enabling higher resolutions, central management, and advanced video analytics. When evaluating CCTV camera price in Bangladesh, calculating total hardware scope—including recorders, storage drives, and power supplies—ensures smooth commissioning.
Many specialised surveillance products, enterprise recorders, and large optical zoom units in our catalogue are listed as Call for Price. You can obtain formal proposals for single units or comprehensive project bills of quantities through our quotation form, hotline, or email. Our team assists with equipment sourcing, corporate and bulk orders, installation guidance, and ongoing technical support for your team in Dhaka and across the country.
Key factors when specifying surveillance hardware
Indoor vs outdoor coverage
Outdoor perimeter locations require weather-resistant housings rated IP66 or IP67 to withstand heavy seasonal rain, humidity, and airborne dust. Vandal-resistant dome housings rated IK10 protect cameras in public corridors or loading bays, while compact turret or bullet cameras suit sheltered indoor offices.
Resolution, lens size, and field of view
Resolution needs depend on operational goals: wide-area situational awareness requires 2 MP to 4 MP sensors, while identification checkpoints, cash counters, and entry gates benefit from 5 MP to 8 MP (4K) sensors. Fixed wide lenses (2.8 mm) cover broad indoor reception areas, while narrower lenses (4 mm to 6 mm) or motorised varifocal lenses focus on distant vehicle lanes.
IP network cameras vs analogue HD cameras
IP camera installations transmit digital video over Cat6 ethernet cabling and power devices via PoE network switches, simplifying cable pulls. Analogue HD cameras (using HD-TVI, CVI, or AHD formats) communicate over RG59 coaxial cables to DVRs, making them practical when replacing legacy cameras without altering existing wiring runs.
Recorders and hard drive storage sizing
Ensure the NVR or DVR provides enough physical channels and incoming network bandwidth for all cameras plus future expansion. Storage retention depends on camera count, resolution, framerate, video compression (such as H.265 or H.264), and recording schedule (continuous vs motion-triggered). High-end surveillance setups utilise dedicated 24/7 surveillance-grade hard drives to maintain reliable multi-week video archives.
PoE switch selection and power budget
For IP systems, calculate the total power consumption of all connected cameras against the power budget of your PoE or PoE+ network switch. Standard indoor fixed cameras draw 4W to 8W, whereas high-powered PTZ cameras with long-range infrared illuminators and internal heaters may require PoE+ (802.3at) or Hi-PoE supplies.
Night vision and illumination range
Low-light performance is critical in dimly lit alleys, perimeter boundaries, and unlit storage interiors. Check the effective infrared (IR) distance specification to match the monitoring area, or opt for full-colour low-light cameras with auxiliary warm LED illumination to capture colour details 24 hours a day.

Frequently asked questions
How can I get pricing for Call for Price surveillance items?
Many commercial security items, enterprise NVRs, and specialised cameras are listed with Call for Price status. You can request formal pricing by submitting a list through our Request a Quotation page, calling our direct hotline, or emailing our sales desk. We provide written quotations detailing hardware specifications and availability.
How do I calculate camera channel count and storage capacity for an office or industrial depot?
Map each entry point, inventory aisle, perimeter fence, and public area requiring visual coverage to establish your channel count, then select an NVR with spare channel capacity for future expansion. For storage calculation, multiply the daily data rate per camera—governed by resolution, frame rate, and compression format like H.265—by your required retention period (typically 15 to 30 days) to establish the necessary total hard disk capacity.
Can I submit an existing project bill of quantities (BOQ) or tender equipment list for a quote?
Yes. Procurement officers, contractors, and project planners can upload or submit their complete equipment schedules directly via our Request a Quotation form or by emailing our corporate sales desk. Our team reviews line items to provide model availability, unit quotations, and compatible component recommendations.
Does the Shelly International catalogue include both recorders and surveillance hard drives?
Yes. Our catalogue features standalone DVR and NVR recorders alongside compatible surveillance-grade hard disk drives, network PoE switches, camera mounts, and power distribution units. This allows organisations to source matching components for complete recording setups from a single supplier.
