The Best Home Surveillance Cameras

Best home security cameras of 2020

It has never been easier to keep an eye on your home, thanks to a new wave of connected home security cameras. The streaming video cameras connect to your home WiFi network to send alerts, video clips, and live video feeds to your smartphone, allowing you to monitor activity while you're away.
New video surveillance systems based on P2P collects multimedia streams generated by surveillance cameras, optimizes their transmissions with SVC according to network condition and stores them in a cloud storage system in an efficient and secure way.

Home Surveillance Cameras
Traditional analog video has been around since the 1920s and that same basic technology is used by most CCTV video surveillance systems today. Just as CDs and DVDs have replaced audiocassettes and VHS tapes, IP-based networking and video storage systems are replacing analog solutions. There are still numerous areas where analog systems perform well and can meet the stated requirements of proper video surveillance.

Security cameras can be stand-alone devices or part of a system depending upon the complexity of your security needs. In order to meet your security objectives, cameras (or signs saying cameras are present) must be visible and the cameras must be able to record, store and transmit footage (or be connected to recorder or system that can do so).

AI Security
AI is becoming more and more universal. AI data is initially analyzed by a computer and then sent to the server to be analyzed. This improves speed and efficiency of analyzing the data and the need to store large amounts of data is reduced. This will also help improve the costs of having AI security.

Home Security Cameras and Video Surveillance Equipment
There are two types of cameras used for surveillance - analog and IP (internet protocol), which are digital cameras.

Analog cameras: These are usually lower resolution than the more modern IP technology, and require cable connections to a DVR to record and store footage, plus wired connections for power. With the DVR, the footage can be viewed on a monitor in real time or a router and modem can be connected to transmit the footage. These cameras cost less than digital cameras, but because their field of vision is smaller, more cameras may be needed. There are more design options for analog cameras, so you may find the right camera for your needs at a lower cost than digital. You also won't lose the network bandwidth that digital cameras take up.

Digital cameras: IP cameras are higher resolution, which generates clearer images but, as we said, use more bandwidth to transmit and require more storage space. Cameras connect to a network video recorder (NVR) via a PoE (Power over Ethernet) switch, which has ports for many cameras and then uses just one cable to connect to the NVR and power source. This reduces the number of cables needed but can put a drain on your network bandwidth.

There is no limitation to where cameras can be placed in relation to the NVR, and wireless network access enables remote viewing of footage. Also, the digital feed can be encrypted. Wi-Fi cameras do, however, raise the concern of potential hacking, so it is important to understand the security features of your cameras.
