However, neither protocol provides the bandwidth
that you get with Wi Fi, which is why it is usually used in security cameras to provide smooth video streaming, and in other devices that require a fat pipe. Moreover, Z Wave and Zigbee devices are connected and controlled using a hub, while Wi Fi devices can be connected directly to your home network and controlled with an app. Finally, Z Wave and Zigbee devices use AES 128 encryption, and since they operate in a closed system with a dedicated hub, they offer more security than Wi Fi devices. Any smart security system worth its salt offers components that work together in a seamless environment and can be manipulated using customized rules. For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered. Some systems store recorded video locally on an SD card or a solid state drive, while others offer cloud storage. Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to overwrite video you may need later. Cloud storage
makes it easy to store and access recorded video, but it can cost hundreds of dollars per year depending on your subscription. Some systems offer both cloud storage and local storage, and some provide a dedicated storage drive that gives you DVR capabilities with time lapse recording, which makes it easy to find a video event that took place at a specific point in time. All of the systems we've tested feature an app that lets you use your smartphone as your command center to arm and disarm the system, create rules, add and delete components, and receive push notifications when alarms are triggered. Most apps also allow you to do things like view live and recorded video, lock and unlock doors, change thermostat settings, and silence alarms.

Do you intend to upgrade by adding more cameras later on?If you think you need only 2 cameras now, get a 4 channel system. If you think you need just 4 cameras right now, go for the 8 channel. Once you start enjoying the security provided by your spanking new CCTV system, you will enjoy the option to add more cameras. But if you want that luxury, plan ahead. Do you want automatic redundant storage?Most NVRs can record only to one hard disk. This means
data storage is not redundant – a hard disk failure or theft of the NVR would mean that you lose all your recorded footage. USB backup is supported on most NVRs to mitigate against this risk but ideally the NVR should have at least 2 hard disk bays and automatically write a
copy of the footage to the second hard drive. The other option to explore is whether the NVR can write the footage to a remote network location such as a NAS.

com and iControl are the two biggest. The former has partnered with more than 2,500 dealers and the
latter with ADT and Comcast. Among other things, you’ll have to decide between a “cellular primary” or “broadband primary” system. The former is a wireless
connection to the monitoring station, making it immune to power outages or someone cutting a cable. It is limited, however, with regard to transmitting large quantities of video, so many cellular primary systems incorporate broadband for video. Broadband primary services, on the other hand, have cables running down the side of a house that can be cut, thereby disabling the system.
