## 10 Common Questions About HIKVISION DS-2CD2721G0-IZS(2.8-12MM)(C)
The HIKVISION DS-2CD2721G0-IZS is one of the most popular IP cameras among factories and warehouses in Thailand. With its robust build, excellent low-light performance, and full HD resolution, it delivers reliable surveillance in demanding environments.
Below are the 10 most frequently asked questions from our customers, answered based on official specifications:
### 1. Is this camera suitable for factory or warehouse use?
Yes, absolutely. The DS-2CD2721G0-IZS is designed for harsh environments such as industrial plants, warehouses, and outdoor areas. It features an IP67 rating, meaning it’s fully protected against dust and water ingress—even during heavy rain or dusty conditions.
Additionally, it operates reliably in extreme temperatures ranging from -30°C to +60°C, making it ideal for uncontrolled warehouse spaces or industrial zones with high heat from machinery.
### 2. What resolution and video formats does it support?
The camera delivers Full HD 1920×1080 resolution with two frame rate options:
– 1920×1080 @ 25fps (Progressive)
– 1920×1080 @ 30fps (Normal)
It supports multiple video compression standards: H.265+/H.265/H.264/MJPEG. H.265+ offers up to 50% smaller file sizes compared to H.264, significantly reducing storage and bandwidth usage—perfect for long-term monitoring in large facilities.
### 3. How well does it perform in low light? Can it work at night?
Yes. The camera has a sensitivity of 0.028 Lux (F2.0, AGC ON) and can operate at 0 Lux with infrared (IR) illumination. It features built-in IR LEDs with a range of up to 30 meters.
This makes it ideal for night surveillance around warehouse perimeters, loading docks, or storage zones without requiring additional lighting—reducing energy costs and improving security coverage.
### 4. What power supply options are available?
The camera supports two power inputs:
– DC12V
– PoE (Power over Ethernet)
PoE compatibility is a major advantage—it allows both power and data to be transmitted over a single Ethernet cable. This simplifies installation, reduces clutter, and integrates seamlessly with existing network infrastructure.
### 5. Can it record to an SD card?
Yes. The camera includes an onboard microSD card slot (supports up to 256GB, card not included). This is useful for local backup in case of network failure or NVR downtime.
We recommend using high-quality Class 10 or UHS-I microSD cards to ensure stable recording and prevent data loss.
### 6. Does it support HIK-Connect cloud service?
Yes. The camera is compatible with HIK-Connect, HIKVISION’s cloud platform. This allows remote access via smartphone or tablet without needing a dedicated server or domain setup.
Simply install the HIK-Connect app, log in with your HIKVISION account, and view live feeds or playback recordings anytime—ideal for business owners who travel frequently.
### 7. What anti-noise and anti-glare features does it have?
The camera includes advanced technologies:
– **3D DNR (3D Digital Noise Reduction):** Reduces image noise in low-light conditions, ensuring clear video even at night.
– **BLC (Backlight Compensation):** Automatically adjusts exposure when bright light comes from behind (e.g., open doors or windows), improving visibility of people or objects in front.
These features enhance image quality and reduce false alarms during critical monitoring.
### 8. Can I adjust the focal length? What lens does it use?
Yes. It comes with a varifocal lens (2.8–12mm), allowing you to adjust the field of view from 80° (wide-angle) to 30° (telephoto):
– 2.8mm: Ideal for monitoring wide areas like parking lots or warehouse aisles.
– 12mm: Best for focusing on specific points like entry doors or high-value storage zones.
Focusing can be done manually or via software, offering flexibility for various installation needs.
### 9. What is the warranty period? Can it be repaired if damaged?
The camera comes with a 36-month (3-year) official warranty from the date of purchase. Coverage includes the camera body and internal components, excluding damage from accidents or improper installation.
If issues arise, CYN Communication—authorized HIKVISION distributor in Thailand—offers professional repair services with spare parts available. Repairs are typically completed within 3–5 business days.
### 10. What is the price? Are there any promotions?
The current price is **฿3,420** (inclusive of 7% VAT), based on the latest price list (2026-02-26).
Promotions may include free accessories such as 32GB microSD cards or high-quality PoE cables. For complete system setups (e.g., 4 cameras + NVR + installation), contact CYN Communication for exclusive bundled pricing.
