What do I need to have a complete CCTV system?
A CCTV system is based on a digital video recorder and DVR. These cameras are usually connected to the DVR and auxiliary power supply. Since the DVR takes all the camera outputs, arrange them and stores them it’s the heart of CCTV. Apart from these, the cameras and the cables are also very important. The installation company will, therefore, look at your system and choose the camera that’s best for you.
What are some of the most common problems with CCTV cameras at night?
The most common problem with CCTV cameras is not seeing anything on the screen at night. When it comes to this problem you need to check out all the things and ensure that the camera has power, secure connections, and the infrared is illuminating. Another problem may also be the voltage drop. If there isn’t enough copper or the cable run is too long, you could experience a voltage drop. If you are using the CATS cable to connect the camera to the power supply and DVR you need to ensure that you are using pure copper instead of copper clad in aluminum.
What is IR Camera, Day and Night Camera
IR cameras refer to an Infrared camera. These cameras have image sensors that are designed in such a way that they can sense infrared light produced IR LEDs and process them. Just like the Day and Night Cameras they can be turned into monochrome when their illumination falls below certain lux. However, unlike Day and Night cameras. IR cameras can easily capture video images in total darkness by using an infrared source of light. On the contrary, Day and Night cameras are types of cameras that can provide video surveillance even when there is low illumination. Although they display full color during the day, at night they only produce monochrome images. They’ve been designed to increase their light sensitivity when there is poor lighting condition and even reduce the level of noise in the images.
What is the difference between Embedded DVR and a PC based DVR
A PC based digital video recorder basically refers to a computer that has been designed with software and hardware to function as DVR. On the other hand, an embedded video recorder is a machine that has been made specifically to record any video input from CCTV cameras. In embedded DVR, there is only one circuit. Although there were some differences between embedded and PC based machines, with recent development in technologies the differences are increasingly becoming less. However, the good thing about embedded DVR technology is that they are stable and reliable. The PC based digital video recorders are easier to interact with since you only need a mouse and on-screen menus.
Why should you consider IP CCTV?
IP CCTV is not only the latest technology but also offers and comprehensive and feature-rich set of tools. These tools are a range of data and image software processing machines that provide superior identification, viewing, and analysis of data. Centralized Computer systems and servers provide the best performance and support corporate governance. By having a greater imaging power it means the IP CCTV is able to capture much more details than the previous technology. They provide the ability to zoom and better quality playback while maintaining image fidelity. More so, its key capabilities include predicting the likely actions, facial recognition, and video analytics.
