Off-Grid CCTV For Hydropower Sites: Remote Monitoring With HiTOP

Off-Grid CCTV for Hydropower Sites: Remote Monitoring with HiTOP

Remote hydropower sites can be difficult to monitor. Intake screens, turbine houses and access roads may be spread across a large area, while mains power and network infrastructure are often limited or completely unavailable.

After heavy rain, debris can block an intake screen. At the same time, unmanned turbine houses may face risks such as trespassing, vandalism or equipment theft.

Without remote visual monitoring, operators may need to travel to the site simply to check whether there is actually a problem.

A solar-powered CCTV system offers a more flexible solution.

The BIGLUX HiTOP Solar CCTV Kit combines solar generation, battery storage and CCTV power output in a compact system designed for remote locations where conventional CCTV installation is difficult.

Why Hydropower Sites Need Remote CCTV

Operational data can tell you that something has changed, but it cannot always tell you exactly what happened.

If generation drops after heavy rain, the reason could be a blocked intake, debris around the weir, low water flow or another physical problem.

A remotely accessible camera gives operators immediate visual information before sending personnel to the site.

This can help answer a simple but important question:

Do we actually need to send someone there?

Remote CCTV can also improve security around unmanned infrastructure. Turbine houses often contain electrical equipment, control panels and valuable cabling, while access roads may have little or no supervision.

With cameras installed at key locations, operators or security teams can monitor activity remotely and respond more quickly when something unusual happens.

Why Use Solar-Powered CCTV?

Traditional CCTV normally requires access to power and communication infrastructure.

At a remote intake, gate or access road, installing this infrastructure may require trenching, electrical work and long cable runs.

HiTOP provides an alternative.

The system combines a 200W bifacial solar panel, 1280Wh LFP battery and MPPT solar controller, allowing compatible CCTV equipment to operate independently from mains power.

It supports 12V, 24V and 48V DC outputs, making it suitable for different CCTV configurations.

Under approximately a 14W continuous load, the standard battery can provide around 72 hours of backup power without solar charging.

Actual runtime depends on camera consumption, communication equipment, temperature and local solar conditions.

Where Can HiTOP Be Used?

1. Intake and Weir Monitoring

The intake is one of the most useful monitoring points at a hydropower site.

A camera overlooking the intake can help operators check:

intake screen condition;

debris accumulation;

water level and flow conditions;

surrounding infrastructure.

After a storm, the operator can remotely inspect the site first.

If everything looks normal, an unnecessary trip may be avoided. If debris has accumulated, the maintenance team knows what to expect before arriving.

A PTZ camera can also provide wider coverage where several areas need to be viewed from one position.

2. Turbine House Security

At the turbine house, CCTV is mainly used for asset protection.

Cameras can monitor doors, surrounding approaches, maintenance activity and unauthorised access.

Because HiTOP operates independently from the site's main electrical system, the CCTV equipment does not have to rely entirely on the same power infrastructure it is protecting.

Depending on the camera system, features such as motion detection, AI human or vehicle detection, two-way audio and remote alarms can also be integrated.

3. Access Road and Gate Monitoring

In some projects, the best monitoring position is the road or gate leading to the site.

Installing a solar-powered camera at the entrance can provide earlier visibility of vehicles and visitors before they reach critical infrastructure.

Because HiTOP does not require a nearby power connection, cameras can be positioned according to security requirements rather than according to the location of the nearest electrical outlet.

Flexible Installation

HiTOP can be installed on an existing pole, wall or BIGLUX HiPT mounting structure.

This makes it especially suitable for locations where a full mobile surveillance trailer is unnecessary.

For example, if a hydropower site already has a suitable pole near the intake or a wall at the turbine house, HiTOP can provide the independent solar power required for CCTV without introducing a large ground-mounted system.

Customers can also use their own cameras.

This is particularly useful for CCTV installers and security integrators that already work with specific camera manufacturers, VMS platforms or monitoring centres.

BIGLUX can provide the solar power system only, or configure cameras and other equipment according to the project requirements.

Typical HiTOP Configuration

The final configuration should always be based on actual device power consumption and local solar conditions.

A system that performs well in a high-sunlight region may require a different configuration in an area with short winter days or frequent cloudy weather.

Is HiTOP Right for Your Site?

HiTOP is a good option when you need CCTV at a remote location but do not require a full surveillance trailer.

It is particularly suitable for:

hydropower sites;

renewable energy facilities;

remote infrastructure;

access roads and gates;

CCTV integrators;

security companies;

temporary monitoring points.

For applications requiring a high mast, several high-power PTZ cameras or significantly larger battery capacity, BIGLUX can also provide larger solar surveillance tower and trailer solutions.
