DAHUA DH-IPC-PTS2649C-3E3Z-4GB20 Solar Battery Camera | Dual Lens 3+3MP | 4G SIM Card | WizColor | AOV | Construction Site CCTV Singapore
The DAHUA DH-IPC-PTS2649C-3E3Z-4GB20 is a professional dual-lens 4G solar-powered PT network camera designed for remote locations, construction sites, temporary works, infrastructure projects and outdoor areas where fixed power and wired Internet are unavailable.
A specification correction is important for accurate SEO: this model is 3MP + 3MP dual lens, not 4MP, and Dahua officially rates it IP66, not IP67. It combines a fixed overview camera with a motorised PT camera, 6× hybrid zoom, AOV Always-On Video, WizColor, 4G connectivity, 65Wh battery, 8W solar panel, SMD 3.0, Auto Tracking Lite, two-way audio and up to 512GB microSD storage.

Dual Lens — One Camera, Two Views
One of the strongest features of the DH-IPC-PTS2649C-3E3Z-4GB20 is its dual-camera architecture.
Instead of relying on one lens, the unit combines:
3MP Fixed Lens → Overall Scene Monitoring
3MP PT Lens → Pan/Tilt Target Monitoring
The fixed camera maintains the broader overview while the PT camera can follow activity and provide a closer view. Dahua describes the coordinated fixed/PT monitoring design as providing a 360° view without blind spots.
This architecture is particularly attractive for large outdoor areas.
6× Hybrid Zoom
The camera provides 6× hybrid zoom, allowing the system to obtain a closer view of distant activity without requiring a conventional large PTZ camera.
For example:
Fixed Camera Detects Activity
↓
PT Camera Moves Toward Target
↓
Hybrid Zoom Provides Closer View
↓
Tracking Continues
This is useful for temporary construction sites, remote compounds, equipment yards and open areas.
Auto Tracking Lite
The DH-IPC-PTS2649C-3E3Z-4GB20 supports:
Auto Tracking Lite + Linkage Tracking
along with human and vehicle detection.
This allows the PT lens to react to relevant activity detected within the surveillance scene.
Rather than requiring an operator to manually move the camera continuously, the intelligent functions can help automate target monitoring.
AOV — Always-On Video
Another major feature is Dahua AOV Mode – Always-On Video.
Dahua specifically states that AOV enables 24/7 recording with ultra-low power consumption.
This is particularly significant for a battery-powered camera.
In AOV mode, Dahua specifies approximately 170mW consumption when recording one frame every two seconds to the SD card while maintaining the 4G connection.
This provides a different operating concept from ordinary battery cameras that simply sleep until motion wakes them.
WizColor — Low-Light Colour Imaging
Both camera channels use F1.0 optics, with Dahua specifying minimum colour illumination down to 0.0005 lux under its stated test conditions.
Dahua's WizColor technology is intended to deliver useful colour imagery in extremely low-light conditions.
For construction sites and remote facilities, colour information can be particularly valuable when identifying:
Clothing • Vehicles • Machinery • Equipment • Objects
during nighttime incidents.
4G SIM Card Connectivity
The camera incorporates 4G cellular connectivity, removing the requirement for a fixed broadband connection at the installation location.
A typical architecture is:

4G SIM Card / Mobile Network
↓
Internet
↓
DMSS Mobile App
This makes the camera particularly useful where there is:
No Fibre + No LAN + No Wi-Fi + No Fixed Internet
The EAU/EUR version supports multiple LTE-FDD and LTE-TDD bands, but the exact regional variant and local operator compatibility should be checked before deployment.
Solar Panel + 65Wh Battery
The camera contains a:
65Wh Built-in Lithium Battery
and comes with an:
8W Solar Panel
It can additionally be charged through USB Type-C with QC2.0 support.
The basic power architecture is:

DUAL-LENS 4G CAMERA
This eliminates the need to install conventional AC power at many temporary or remote locations.
Actual autonomy depends on sunlight, operating mode, 4G signal quality, tracking frequency, illumination usage, temperature and battery condition.
Up to 512GB Local Storage
The camera supports:
microSD Card up to 512GB
for local recording.
This is especially valuable for 4G CCTV because continuously uploading every second of video through a cellular network can consume substantial mobile data.
A more efficient architecture can be:
Local SD Recording
4G Alarm Notification
Remote Live View When Required
This reduces unnecessary SIM-card data usage.
Active Deterrence
The camera provides both:
White-Light Warning
and
Audible Warning
Dahua specifies three available alarm sounds, with configurable volume and playback repetitions.
This creates a useful security sequence:
DETECT → TRACK → RECORD → ALERT → DETER
For unmanned construction sites and remote facilities, active deterrence can be particularly valuable.
Two-Way Audio
The camera has a:
Built-in Microphone
Built-in Speaker
supporting two-way communication.
An authorised remote operator can therefore potentially view activity and communicate with a person at the site.
This is useful for security warnings such as unauthorised entry into a restricted work area.
DMSS Mobile App
Dahua officially lists DMSS as the management software/mobile client for Android and iOS.
This provides a convenient architecture for remote monitoring:

Solar 4G Camera
↓
Mobile Network

DMSS

Security / Project Management
The actual remote functions available depend on the camera configuration, network connectivity and user permissions.
SmartPSS Compatibility — Check Before Specifying
For this particular model, Dahua's current official specification lists DMSS as the management software. It does not list SmartPSS on the current product specification.
Therefore, I would avoid advertising:
“SmartPSS Supported”
unless the exact firmware/version has been tested successfully.
For professional projects requiring centralised PC/VMS management, confirm software compatibility before tender submission.
Singapore MOM Construction-Site VSS Requirements
This camera is potentially interesting for Singapore construction-site monitoring, but “MOM compliant” should not be claimed based on the camera model alone.
Since 1 June 2024, Singapore MOM requires construction worksites with a contract value of S$5 million and above to install Video Surveillance Systems (VSS).
MOM states that the VSS must be capable of:
Minimum HD 1080 resolution
At least 12 frames per second
Export to AVI, MP4 or another common multimedia format
Date stamp
Time stamp
Camera identification code
and recordings must generally be retained for at least 30 days, or 180 days after a reportable WSH incident.
The Dahua camera itself provides 3MP at 15fps, exceeding MOM's basic resolution and frame-rate thresholds.
However, compliance applies to the complete VSS deployment, including placement, recording, retention and export—not merely the camera specification.
Better SEO wording:
“Suitable for MOM VSS Construction-Site Applications, subject to complete system design and compliance requirements.”
This is more accurate than claiming the camera itself is “MOM Certified.”
[Singapore MOM – Video Surveillance System Requirements for Construction Sector](https://www.mom.gov.sg/workplace-safety-and-health/safe-measures/sectoral-level/video-surveillance-system-for-construction-sector?utm_source=chatgpt.com)
Where MOM Requires VSS Coverage
For applicable construction worksites, MOM specifies VSS coverage at areas involving activities such as work at height above 2m, scaffolding/formwork, excavation and shoring, lifting operations, industrial trucks, hazardous vehicular traffic, loading/unloading and certain confined-space work.
A solar/4G camera can be particularly useful where these work zones move as construction progresses.
Instead of repeatedly installing:
AC Power + CAT6 + Network Switch + Fibre
the camera can potentially be relocated with the changing work area.
Workplace Privacy & CCTV
MOM also notes that workplace surveillance involving personal data must comply with applicable PDPA obligations. Organisations should establish clear rules, use surveillance at appropriate safety/security locations, inform workers of the purpose, and implement safeguards around storage and use of recordings.
Therefore, construction-site CCTV should be deployed as part of a documented WSH, security and data-management policy.
Ideal Applications
The DH-IPC-PTS2649C-3E3Z-4GB20 is particularly suitable for:
Construction Sites • Temporary Worksites • Roadworks • Excavation Areas • Equipment Yards • Remote Compounds • Farms • Vacant Land • Car Parks • Infrastructure Projects • Outdoor Events • Temporary Security Deployments
Its strongest value proposition is:
NO AC POWER + NO LAN + NO WI-FI = SOLAR + BATTERY + 4G CCTV
