Your company has recently been hired to install a smart security system for a large office building. the system will include security cameras, voice-controlled lights, smart locks, and smart thermostats. some of the security cameras will be installed outdoors throughout the parking lot. which wireless iot protocol should your company use for the installation? 1. wi-fi because it is always encrypted2. zigbee because it is always encrypted3. z-wave because it is the fastest wireless standard4. bluetooth because it is easiest to configure

Z-Wave

Explanation:

1.Wi-fi because it is always encrypted. This is good because Bandwidth is high—up to 2 MHz, however it only works if the signal is strong and device is close to the access point. Its average range is between 30 to 100 meters. This drawback only makes this technology not a good option.

2. ZigBee because it is always encrypted, ZigBee has lot of edge like largest number of device to connect 6500 theoretically, low power usage, faster and others compared to other which would have made it a better option to recommend to my company but it has interoperability issues

3. Z-Wave because it is the fastest wireless standard apart from this Z-wave has better interoperability, reliability, low frequent which does not interfere with Wi-Fi network, maintain backwards compatibility across all versions which is good for maintenance, Z Wave network to have greater ranges and ability to “bend” around obstacles.

4. Bluetooth because it is easiest to configure Low Energy (LE) is better at conserving power, it has a much longer range compared to others —up to 300 feet, under ideal circumstances—its low transmission rate will keep it from being used for data-heavy applications such as video.

In view of security and distance and compared with other IoT protocol i would recommended Z-Wave

the only way i would see could be an autoclicker type software. but that is very time consuming.
