If you’re setting up a security system in 2025, there’s really only one direction worth going — IP cameras. Sharper footage. Smarter detection. Remote access from your phone, anywhere in the world. Easier installation. And a future-proof system that grows with your needs. Whether you need a Hikvision IP camera for a home or office setup, a Dahua IP camera for a commercial property, a UNV camera for a large-scale installation, or a weatherproof bullet camera for outdoor perimeter coverage — Marshmallow Tech carries a curated range of professional-grade IP CCTV cameras at honest prices across Bangladesh. Because your security system is only as good as the cameras at the heart of it.
An IP camera (Internet Protocol camera) is a digital security camera that captures video and transmits it over a network — either your local area network (LAN) via ethernet cable, or wirelessly via Wi-Fi — rather than through the analog coaxial cable used by traditional CC cameras. The term IP CCTV camera combines the network-connectivity of IP technology with the closed-circuit monitoring purpose of CCTV — giving you the best of both worlds.
The shift from analog to IP camera systems represents the single biggest upgrade in security camera technology in the last decade. Here’s why:
The bullet camera is the most recognisable security camera form factor — a cylindrical, tube-shaped unit typically mounted on walls or ceilings, pointed in a fixed direction. Bullet cameras are highly visible, which itself serves as a deterrent. Their elongated design accommodates longer focal length lenses, making them ideal for monitoring long distances — corridors, driveways, perimeter fences, and parking areas.
Most bullet cameras are rated for outdoor use with IP66 or IP67 weatherproofing, making them a dependable choice for Bangladesh’s monsoon conditions. Both Hikvision and Dahua produce outstanding bullet camera models across 2MP, 4MP, and 8MP resolutions.
Dome IP cameras are housed in a compact dome-shaped enclosure, typically ceiling-mounted. Their discreet design makes it difficult to determine the exact direction the camera is pointing — a useful deterrent in retail and office environments. Dome cameras are standard for indoor use in shops, offices, hotel lobbies, and apartment common areas.
PTZ IP cameras can be remotely controlled to pan horizontally, tilt vertically, and zoom optically — covering a wide area with a single camera. They’re used in large spaces like warehouses, parking lots, and public areas where flexible coverage is needed. PTZ cameras from Hikvision and Dahua support auto-tracking, automatically following moving subjects within the frame.
A turret (or eyeball) IP camera combines the compact dome housing with the flexibility of an adjustable ball-joint mounting — allowing the camera angle to be repositioned without removing the housing. These are increasingly popular for general indoor and outdoor installation due to their clean appearance and installation flexibility.
Fisheye IP cameras use ultra-wide lenses to capture a 180° or 360° panoramic view of an entire room from a single ceiling-mounted unit. A single fisheye camera can replace multiple standard cameras in open-plan spaces — reducing hardware costs while maintaining full coverage.
Hikvision is the world’s largest security camera manufacturer and the dominant brand in Bangladesh’s surveillance market. Hikvision cameras are found in homes, offices, factories, hospitals, government buildings, and retail chains across the country — a testament to their reliability, performance, and the depth of their installer network.
Hikvision IP camera technology highlights:
Hikvision’s range in Bangladesh spans from entry-level 2MP bullet cameras and dome cameras to 4K AI-powered IP cameras and PTZ units for enterprise use. Explore Hikvision’s full IP camera range here.
Dahua is Hikvision’s closest global rival and equally trusted in Bangladesh’s professional security installation market. Dahua IP cameras match Hikvision on technology and often offer competitive pricing — making them the preferred choice for many installers and system integrators across Bangladesh.
Dahua IP camera technology highlights:
Dahua bullet cameras, dome cameras, and PTZ units are available in 2MP, 4MP, and 8MP resolutions across their economic, lite, and pro product tiers. Learn more about Dahua’s IP camera technology here.
UNV — short for Uniview — is China’s third-largest professional IP camera manufacturer, and a brand with a growing presence in Bangladesh’s security installation market. UNV cameras are particularly popular among professional installers and system integrators for their competitive pricing, strong technical specifications, and excellent compatibility with third-party NVR systems including their own UniArch platform.
UNV camera highlights:
UNV cameras are a strong choice for large-scale installations in Bangladesh where balancing performance and cost across a high camera count is a priority. For buyers comparing Hikvision cameras, Dahua cameras, and UNV cameras for a professional installation — all three are credible, professional-grade options.
PoE IP cameras (Power over Ethernet) receive both power and data through a single Cat5e or Cat6 ethernet cable connected to a PoE NVR or PoE switch. This is the professional standard for permanent installations — stable, reliable, no Wi-Fi dependency, and no need for separate power outlets at each camera location.
Wireless IP cameras connect via Wi-Fi — easier to install in locations where cabling is impractical, but dependent on Wi-Fi signal strength and more vulnerable to interference. For permanent home or business security setups in Bangladesh, PoE is always the recommended approach.
| Resolution | Megapixels | Coverage Area | Best For |
|---|---|---|---|
| 1080p | 2MP | Standard indoor/outdoor | Entry-level home use |
| 4MP | 4MP | Wider areas with detail | Home, small business |
| 4K | 8MP | Large spaces, face ID | Retail, office, critical areas |
| 12MP | 12MP | Very wide area coverage | Enterprise, large perimeter |
For most home and small business IP CCTV camera setups in Bangladesh, 4MP is the recommended minimum — providing enough resolution to identify faces and vehicle plates at typical monitoring distances.
Traditional IP cameras use infrared (IR) night vision — producing black-and-white footage in low light. Modern IP cameras from Hikvision (ColorVu) and Dahua (Full-colour/Starlight) produce full-colour night vision using supplemental lighting or high-sensitivity sensors. Colour night vision is significantly more useful for identification — capturing clothing colours, vehicle colours, and visual details that black-and-white footage cannot.
For any outdoor bullet camera installation in Bangladesh — especially for entrances, parking areas, and perimeter coverage — full-colour night vision is strongly recommended.
Basic IP cameras detect any motion and alert you — including passing animals, blowing leaves, and rain. AI-powered IP cameras (Hikvision AcuSense, Dahua SMD Plus, UNV EasyStar) filter motion alerts to only notify you when a human or vehicle is detected. In Bangladesh’s environment — where outdoor cameras frequently trigger on trees, insects, and animals — AI detection is a practical necessity rather than a luxury.
IP cameras store footage in three ways:
For Bangladesh, NVR-based storage with a 1TB–4TB hard drive is the standard approach for any multi-camera IP CCTV camera installation.
Bangladesh’s monsoon season demands proper weatherproofing for any outdoor IP camera or bullet camera installation. Look for:
All outdoor Hikvision cameras and Dahua cameras in the standard product range meet IP66 minimum — sufficient for Bangladesh’s monsoon conditions.
ONVIF (Open Network Video Interface Forum) is the universal IP camera communication standard. An ONVIF-compliant IP camera works with any ONVIF-compatible NVR — regardless of brand. Hikvision cameras, Dahua cameras, and UNV cameras are all ONVIF-compliant, giving you flexibility to mix brands in a single system when needed.
| IP Camera | Analog CC Camera | |
|---|---|---|
| Resolution | 2MP–12MP+ | Up to 2MP (typically lower) |
| Cabling | Single Cat5e/Cat6 (PoE) | Coaxial + separate power |
| Night vision | IR or full-colour | IR only (standard) |
| Smart features | AI detection, face ID, ANPR | Basic motion only |
| Remote access | Full live view + playback | Limited (requires DVR setup) |
| Scalability | Add cameras easily via NVR | Rewiring often needed |
| Cost | Slightly higher upfront | Lower upfront |
| Best for | New installations | Upgrading existing analog systems |
For any new security camera installation in Bangladesh in 2025, IP cameras with an NVR is the unequivocal recommendation.

Q1. What is an IP camera and how does it differ from a regular CC camera? An IP camera transmits digital video over a network (LAN or Wi-Fi), while a traditional CC camera sends analog video over coaxial cable to a DVR. IP cameras offer significantly higher resolution (2MP–12MP vs typically under 2MP for analog), smarter features like AI motion detection, easier remote smartphone access, and simpler PoE cabling. For new installations, IP CCTV cameras are the strongly recommended choice.
Q2. Which is better — Hikvision IP camera or Dahua IP camera? Both are world-class professional security camera brands. Hikvision cameras have the larger market share in Bangladesh and a wider installer network. Dahua IP cameras match Hikvision on technology — including AI detection, full-colour night vision, and 4K resolution — often at competitive price points. Either brand is an excellent choice; the decision often depends on your installer’s experience and existing system equipment.
Q3. What is a UNV camera and is it reliable? UNV (Uniview) is China’s third-largest professional IP camera manufacturer — a genuine tier-one security camera brand used in large commercial and government installations worldwide. UNV cameras are ONVIF-compliant, offer 2MP–12MP resolution, AI detection, and LightHunter low-light technology. They’re particularly well-suited for cost-sensitive large-scale installations in Bangladesh.
Q4. What is a bullet camera and where is it best used? A bullet camera is a cylindrical, tube-shaped IP camera mounted on a wall or ceiling, pointing in a fixed direction. Its elongated design accommodates longer lenses for distance monitoring, and its visibility serves as a deterrent. Bullet cameras are best used for outdoor perimeter coverage — entrances, driveways, parking areas, and long corridors. Most outdoor bullet cameras carry IP66 weatherproofing for monsoon protection.
Q5. How many IP cameras do I need for my home in Bangladesh? For a typical Bangladeshi home, 4 IP cameras provide comprehensive coverage — main entrance/gate, rear entrance, parking/garage, and one indoor or blind-spot camera. Larger properties, multi-storey buildings, or homes with large compounds typically need 6–8 cameras. A professional installer can assess your property and recommend optimal placement for complete coverage.
Q6. Do I need internet for my IP CCTV camera system to work? No — an IP camera system with a local NVR records footage 24/7 to the NVR’s hard drive without any internet connection. Internet connectivity adds the ability to view live footage and playback remotely from your smartphone via Hikvision‘s Hik-Connect app or Dahua‘s DMSS app. The recording system itself functions independently of internet availability.
Q7. What is PoE and why does it matter for IP cameras? PoE (Power over Ethernet) allows a single ethernet cable to deliver both data and electrical power to an IP camera — eliminating the need for a separate power outlet at every camera location. A PoE NVR or PoE switch powers all connected cameras through the same cable that carries video. This significantly simplifies installation, especially in locations where running separate power cables is difficult or expensive.
Q8. What is the difference between IP66 and IP67 weatherproofing on IP cameras? Both ratings indicate the IP camera is fully dustproof. IP66 means protected against powerful water jets — sufficient for heavy monsoon rain. IP67 adds protection against temporary submersion in water up to 1 metre for 30 minutes. For standard outdoor bullet camera and dome camera installations in Bangladesh, IP66 is the minimum acceptable rating — and is standard on all outdoor Hikvision cameras and Dahua cameras in their core product range.
