Network Video Recorder (NVR)

Network Video Recorder (NVR) Solutions in Bangladesh

The heart of your IP surveillance system: record, store and retrieve evidence reliably

Your cameras capture the footage, and your NVR protects it. A Network Video Recorder receives video from IP cameras over the network, stores it securely and lets you search, play back and export footage when an incident happens. The right NVR keeps every camera recording at full quality, gives you enough storage to meet your retention needs and protects your evidence if a hard disk fails.

Smart Safety & Automations Ltd (SSAL) supplies and configures NVRs for homes, shops, offices, factories, banks, hospitals, campuses and government sites across Bangladesh. Our engineers size each recorder to your camera count, resolution, retention period and growth plans, so you don’t run out of storage or channels later.

NVR Types We Offer

PoE NVRs
Built-in PoE ports power and connect IP cameras directly. They make small and medium installations simple, with fewer switches and less cabling.

Standard (Non-PoE) NVRs
These connect to cameras through external network switches. They suit larger sites where cameras are spread across buildings or floors.

Enterprise / High-Channel NVRs
High channel capacity, multiple hard-disk bays and high incoming bandwidth for large factories, campuses, banks and multi-building sites.

RAID-Enabled NVRs
RAID storage protects recorded footage if a hard disk fails. They are essential for banking, government and other compliance-critical sites.

AI / Smart NVRs
Built-in analytics for face search, vehicle search, intrusion alerts and smart event filtering, so you find footage in minutes, not hours.

Hybrid Recorders
They record both IP and HD analogue cameras, so you can upgrade an existing CCTV system step by step. (Link to: HD / Analogue Camera page)

How We Size Your NVR

Choosing an NVR goes beyond the number of channels. Our engineers calculate:

Number of cameras: today, and planned future additions
Camera resolution & frame rate: higher quality needs more bandwidth and storage
Recording mode: continuous, scheduled or motion/event-based
Retention period: how many days of footage you need to keep
Storage protection: whether RAID or backup is required for compliance

The result is a recorder and hard-disk configuration that matches your actual needs, without overspending or running short.

Frequently Asked Questions

What is the difference between an NVR and a DVR?
An NVR records IP cameras over a network. A DVR records analogue or HD analogue cameras over coaxial cable. Hybrid recorders support both.

How many days of recording will I get?
That depends on the number of cameras, resolution, recording mode and hard-disk capacity. We calculate this for you and recommend the right storage for your target retention.

Can I use any brand of IP camera with my NVR?
Many NVRs support third-party cameras through the ONVIF standard, but features like analytics work best within the same brand. We check compatibility before installation.

What happens if a hard disk fails?
On RAID-enabled NVRs, recordings stay protected even if a disk fails. For critical sites, we recommend RAID or backup storage.

Can I view recordings on my phone?
Yes. Once the NVR is connected to the internet, you can view live and recorded footage securely through the mobile app.

Do you provide installation and maintenance?
Yes. SSAL handles installation, configuration and commissioning, and offers AMC with 24/7 emergency support.
