The Flir FX and Foscam C2 had the best results with lights on. In low light conditions, the Nest Cam Indoor and the D Link DCS 2630L were better. Aside from overall daytime video quality, we also looked at each camera's picture clarity. Predictably, higher resolution cameras yielded the best results in this test, with 1080p cameras showing greater detail than 720p models. The Flir FX, D Link DCS 2630L and Netgear Arlo Q had the clearest video among 1080p cameras, while the Belkin NetCam HD+ was the best among 720p cameras. We concluded testing by evaluating how well each camera handled motion. The D Link DCS 2630L and the Netgear Arlo Q recorded movement well, while the other cameras had at least some lag and image distortion. Internet speed can affect lag, so motion is often worse on live video feeds, while recordings have fewer problems than live streams. Nighttime videos use infrared light instead of visible light, so they don't match the color or detail of daytime videos. Therefore, we assessed the brightness of the nighttime picture instead, with brighter video producing more detail. The top nighttime security camera was the Belkin NetCam HD+, which illuminated our room better than other cameras.

Closed circuit television CCTV, also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point P2P, point to multipoint P2MP, or mesh wired or wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, stores, and other areas where security is needed. Though Videotelephony is seldom called 'CCTV' one exception is the use of video in distance education, where it is an important tool. In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders DVRs, provides recording for possibly many years, with a variety of quality and performance options and extra features such as motion detection and email alerts. More recently, decentralized IP cameras, perhaps equipped with megapixel sensors, support recording directly to network attached storage devices, or internal flash for completely stand alone operation. The earliest video surveillance systems involved constant monitoring because there was no way to record and store information. The development of reel to reel media enabled the recording of surveillance footage. These systems required magnetic tapes to be changed manually, which was a time consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take up reel.

2. Still, there’s something that feels quite nice about being able to install the system yourself and to get it working right. Some security systems require incorporating your new system with your existing wiring which means you will need to have the right tools for the job. Anytime you’re dealing with wiring and electricity, you really need to know exactly what you’re doing and have the tools to do it properly. Otherwise, you could end up damaging your new equipment, your existing wiring, or creating a fire hazard if it is not installed properly. So unless you truly know what you’re doing, you should probably opt for professional installation, especially if your new security system will need to be hardwired. If you choose a DIY wireless security system, most on the market today are fairly intuitive and easy to install. And, many of them don’t require any special tools or knowledge to get the job done. Whether you’re a senior or simply buying a security system for a senior, I’d recommend Vivint. They have professional installation, so you won’t have to worry about your system working correctly; the person who installed my system was very kind, patient, and most importantly, knowledgeable. This could be very helpful for a senior, who may not know much about modern DIY installation.
