Hard Drives 3 years. Monitors 1 year. 1-year advance replacement warranty when you buy from Custom Video Security. Direct tech support from Dahua to low-voltage installers and to the end-user. 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 […]
Read Now Dahua has a now free app (used to be paid) called gDMSS Plus (Android) or iDMSS Plus (iOS), both of which support 2-way audio communication. You could use wireless dome and bullet cameras for all of the cameras that don’t require audio. The fixed-lens cameras are typically available in 2.8mm or 3.6mm fixed lens options. For the cameras with audio, 2-way audio support would be required on the camera, and those are available in the Dahua N45 series as a motorized-lens WDR bullet or its dome counterpart, either of which would need to be wired, but you can use a wireless bridge to eliminate wiring from the PoE switch to the recorder. Wired cameras typically are much more feature-rich and will have better image quality over wireless cameras. You would connect a speaker and microphone to the camera with 2-way audio. Or you can opt for a speaker/microphone combo for easier installation. ETS makes a speaker/microphone combo, although it’s probably not the best aesthetic design. We have other options available depending on your desired finish, but the ETS runs around $129 with free shipping. You can use wired IP cameras as wireless if you add a Point-to-Point (P2P) wireless bridge and a PoE […]

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, […]
