Best DIY Security Systems In 2021

When you think of increasing your house’s safety with a home security system, you shouldn’t need to worry about monthly fees or professional installation. Think for yourself- isn’t it just so much better to invest in a DIY home security system for which you wouldn’t have to pay for professional installation or sign any long-term contracts? Fortunately, we have come quite far from the earlier days. 

Though there are still some companies out there who make home security systems that professionals have to install, more companies each day are turning towards making DIY security systems. In the case of DIY systems, you would have to order your security system online. Then the company ships you all the equipment along with instructions on how to install it. You can monitor your system yourself, or you could opt for the flexible monitoring plans that some companies offer for which you won’t have to sign any contracts. In this article, you will get to know about the best DIY security systems in the market and the types of DIY security systems, and some general guidelines on installing one.

Types Of DIY Home Security Systems

  1. There are LCD panels in some of the security systems. The LCD panel is like the brain of those systems. Generally, one has to install this panel on a central wall of their house that connects wirelessly to your router or home network. Most of the panels in the security systems contain capacitive touchscreens and use multiple radios to control Z-wave, the Wi-fi, Bluetooth sensors, Zigbee, and other such home automation elements. Some panels also have a cellular radio. This radio connects them to the monitoring center in case you have availed of a professional monitoring plan. In most cases, they would also have a microphone and a speaker, which you can use to communicate with the monitoring agent. 
  2. Some companies use a hub to control the systems. Like controllers of the LCD panels, hubs also have wiring, and radios control many different components. Hubs are typically low-profile devices. These suit your home décor, and you can easily place them on any available flat surface.
  3. The third type of home security controller is an all-in-one type. It is mainly a security camera that contains many wireless radios, sound and motion sensors. It also has a siren meant to scare off any intruders, thus warning you of any intrusions. Some of the controllers of this type also have environmental sensors that monitor the room’s air quality, humidity, and room temperature.
  4. Lastly, almost every innovative home security system in the market can take voice commands as well. Google Assistant and Amazon Alexa are commonly in the systems. Such home security systems would provide support for IFTTT applets too. These enable them to turn any lights on if there is an alarm or change the thermostat settings.

Components That You Will Need

Before you buy a security system, you must know all the components you need and what quantity. Firstly, you will need enough door and window sensors to put them in every door and window of your home. There is no need to put motion sensors in every room but only in the main areas of the house, like in the hallway, foyer, etc., so that you get to know if an intruder comes in. You should invest in PIR or passive infrared sensors. They are cost-effective, environment friendly, and detect body heat quite well. Besides the usual security cameras and video doorbells, you would need thermostats, freeze or flood sensors, glass break sensors, CO and smoke detectors.

Professional Monitoring vs. Self-monitoring

Nowadays, many vendors of DIY security systems are starting to provide professional monitoring services. In some cases, you might need to sign a contract whereas, in others, you would have to pay when you avail the services like when you are away or such. If you use professional monitoring, you will get alerts as usual, but the monitoring center would contact you. If the people at the center cannot reach you or any others on your emergency contact list, they will inform the local authorities regarding the alarm.

Now, let’s talk about self-monitoring. You will be able to self-monitor almost every security system that you think of buying. You would be able to self-monitor via the mobile app, from where you will arm or disarm the system from anywhere. You will be able to monitor the statuses of the sensors and also view recorded or live videos. When a sensor gets triggered, you will receive push alerts or email notifications(in some cases). Then, it’s your wish whether you contact the authorities or not.

How To Install A DIY Security System – General Guidelines

  1. Generally, you would not face any problem installing a DIY security system as they are pretty user-friendly. Even if you are inexperienced, you won’t have much trouble. But you would need to think about where you want to place the hub, security cameras, and sensors. Some corners require a wired connection to a router, while others may use Wi-fi to connect to the network in your home. In any case, the hub should be close to the router you have so that there is maximum connectivity. If you have bought a security system with a touchscreen panel, you need to ensure a power outlet close to it.
  2. Secondly, after installing the mobile app and the hub, you have to install all the sensors. In most cases, the motion sensors and the door or window sensors are already paired to the hub. Thus, to activate the sensor, you only need to detach the battery tab. After that, you will need to click on the option “Add a Device” in the home security system app and name each of the sensors for the back door, front door, etc.
  3. DIY security systems are elementary to install. You have to use double-sided tape to place the components into place. You will also install the doorbells and cameras easily though you would have to pair them by yourself. We expect you won’t run into problems as all the systems come with step-by-step instructions and even voice prompts so that you don’t get clueless while installing the system.
