If you are wondering whether or not you need a security camera at home, the answer depends on the level of security you want to add to your home. Although sensors can detect motion, you cannot see what is going on at your home if you don’t install a security camera. Security cameras get you help faster and camera footage can also be used in a criminal investigation if someone broke into your home.
NVR vs DVR
When you shop for security systems, you will have to pick between a digital video recorder (DVR) and a network video recorder (NVR) recorder. While these options perform the same function, they differ in how they process data and the kind of cameras used. DVR systems process the video data at the recorder while NVR systems encode and process the video data at the nvr camera and stream it to the recorder used for storage and remote viewing. The majority of NVRs are used in IP cameras while DVRS are used with analog cameras. A DVR system is wired while an NVR can be wired or wireless.
Security Camera Features to Look For
Whether you want to go for a wired or wireless camera, you want to delve into the features of the camera including the following:
- Connectivity. Consider whether the camera requires Wi-Fi. Also, does it work on a 2.4 GHz or 5Ghz network? These days, the majority of cameras only work with a 2.4 GHz network, though 5 GHz is becoming common.
- Do you want a plug-in or wireless security camera system for home? If you want a wireless camera, consider its battery life. Does it have a rechargeable or replaceable battery?
- If you will be installing your camera outdoors, you must consider its temperature range and IP rating. If you have temperatures between 0- and 100-degrees F, ensure your camera fits into this range. Also, the IP rating of a camera tells you about its resistance to solids and liquids in a two-digit number with the first number being the solids and the second the liquids.
- Video quality. Most smart security cameras today have 1080p HD resolution. More advanced cameras have 2K or even 4K resolution, which possesses twice the number of pixels as 1080p HD.
- Cameras that can zoom in optically can move in closer to an object. Others can zoom in digitally, which means they can be zoomed in by pinching the live stream on the application. Because the footage of optical zoom is higher-resolution, it is often preferable.
