Very wide product line including: ePoE (converts coax lines to use IP cameras at the lowest cost in the industry; or triples the distance of IP without any need for repeaters/extenders). Starlight cameras see color at nighttime with minimal ambient lighting. Video: https://youtu.be/NaFHmwXI6Zk?t=5. Identify skin color, hair color, clothing color, vehicle color, etc. So much more effective than traditional IR cameras. The levels of Dahua’s starlight are attached. I recommend Starlight+ if you may require viewing in very dark or pitch-black scenes. Or Night Color if you don’t need or don’t want infrared. Night Color cameras have no infrared, which means you can’t use them in pitch-black darkness, but they see at nighttime with minimal ambient lighting like it’s daytime. They have the highest nighttime performance […]

Case Study–Cannabis Grow House In 2017, a Los Angeles County-based grow house, which will go unnamed for security and privacy reasons, contacted us to design and install a security camera system. One of the partners had a copy of his local security requirements for operating the facility, and so we scheduled a free site inspection to survey the property. During the site inspection, we notated the general layout of the facility, noted potential security risks, and recommended cameras and placement that would accommodate the project’s budget while meeting or exceeding the minimum security requirements from the state of CA and City of Los Angeles. On the day of the site inspection, their security consisted of a non-security guard camped out in a trailer on a gated driveway, three dogs, consumer-grade doors and locks, and an intrusion alarm system. The various areas requiring coverage included the entrance, exits, hallways, a large laboratory-style room with expensive lab equipment, several temperature and light-controlled grow rooms, a network/security room with MDF closet where the recorder was to be installed, multiple hallways leading to each of these rooms, and rooftop coverage because of the easy access from a neighboring building. They required at least 90 days […]

A hybrid DVR is a DVR that can accept more than one type of video signal. The three most common video signals on the market today are analog, HD-SDI, and IP. It is advantageous to have a hybrid DVR for many reasons, the most significant of which is to utilize existing analog cameras, while adding megapixel cameras to areas that need more detailed monitoring with clear digital zoom-in capabilities. HD cameras can also be used to minimize analog camera count, as they have more pixels and can cover large areas of real estate with a minimal number of cameras. ANALOG CAMERAS Analog, a closed-circuit television system (abbreviated by CCTV), is the traditional video signal, which has been in use for decades, and is typically carried over coaxial cable. In some cases people use Cat5 network cable to send video and even audio and power over network cable with the use of baluns, which are adapters that convert the camera’s BNC connector to RJ45 for Cat5, or to twisted pair, which is common for video-only signals. The typical distance limit for coaxial cable is between 250 to 450 feet, depending on the quality of the cable. With baluns and Cat5 cable, […]
