Security & Camera Systems

HDH installs security systems that work and are easy to use. Homeowners don’t want to be taught how to alarm their homes. At HDH it is usually just a single button press. We install smoke and fire alarm systems along with carbon monoxide detectors wired to central station. Flood sensors are things that many companies forget to install until it is too late. At HDH we put the well-being of the client first. HDH also personally monitors all of its accounts. If central station cannot reach someone, our office will be sure to find the client no matter where they are.

Security cameras have come a long way since the days of giant housings. Today we install cameras as small as a pinhole and microphones that allow the user to record up to 16 different channels of audio and video that can be viewed for up to 30 days in case of an incident. We also install IP Cameras that have built-in video servers and wire directly to the Internet. These cameras allow people to see and hear from any computer. It also gives the user the ability to move the camera to any angle they wish. Some cameras can even be seen from cell phones.

IP Cameras

An IP camera, is a type of digital video camera commonly employed for surveillance, and which unlike analog closed circuit television (CCTV) cameras can send and receive data via a computer network and the Internet.

GV-FE4301 4MP H.264 WDR

The GV-FE4301 is a fisheye camera that allows you to monitor
all angles of a location using just one camera. The distorted hemispherical image of the fisheye camera will be converted into the conventional rectilinear projection.

Without installing any software, you can watch live view and utilize functions such as motion detection, privacy mask, and alert notification through the Web interface using an IE browser. In addition, the GV-FE4301 seamlessly integrates with the GV-System, providing advanced monitoring and video management features.

The GV-Fisheye IP Camera is designed to be mounted on the ceiling, wall or ground. There are two ways to mount the GV-FE4301 on the ceiling, Hard Ceiling Mount and In-Ceiling Mount. In-Ceiling Mount allows the GV-FE4301 to be mounted into the ceiling, revealing a small portion of the camera.
