In the past, hardwired alarm systems are the only choice for customers who need security equipment to protect premises. Today, with rapid technology evolve, many users shift from hardwired alarm to wireless alarm. It seems home security industry is moving from hardwired to wireless, but as one of mature and stable alarm equipment, some users still favor the hard wired alarm system. In this article, we will show you some basic information about advantages and disadvantages of hardwired alarm systems.
What’s hardwired alarm system ?
Alarm systems are electronic devices that help user to detect intrusion, fire, gas leak, panic and more. Hardwired alarm systems have wires going to window/door sensor, motion sensor, fire smoke sensor and other sensors. In other words, hardwired alarm systems are connecting or communicating sensors via cable.
Low cost fee for equipment and less maintenance
Compared with wireless alarm systems, the cost for hardwired alarm systems equipment is lower (especially for the hardwired door sensors). After complete installation, it requires less maintenance, thus have lower maintenance costs. Wireless alarm systems are adopting wireless RF technology via communication between alarm panels and wireless sensors. All wireless sensors are equipped with RF transmitter and battery, so the cost for equipment is far outweigh a hard wired alarm systems. In addition wireless sensors are powered by battery, when these batteries run out, user have to replace them, this increase the maintenance fee.
Hardwired alarm systems are more secure than wireless alarm systems
Typically the alarm panel comes with heavy duty metal housing with lock design for hardwired alarm system. The system with separate keypad design, allow user to hidden alarm panel in basement or other secret place where is not easy to access for strange people or intruder. With this kind of design, hardwired alarm system still can work, if intruder damage the keypad or cut cables between keypad and alarm panel. Wireless alarm systems are all-in-one system, self-contained with alarm panel and keypad, if you install these self-contained wireless alarm system in front of door, or some place where is easy to access. When intruder damage it, the whole system will dead and complete off.
No signal interference, long range transmission distance
If you have a large villa or big warehouse want to secure, you’d better to choose the hardwired alarm systems. Majority of wireless alarm system with limitation for the signal transmission between alarm panel and wireless sensors. The transmission distance for hardwired alarm system can reach up to 900ft. For installation of hardwired alarm system, you don’t need to worry about the wireless signal strength.
Complicated installation, compared to wireless alarm system
Hardwired alarm systems are using cables between alarm panel and sensors, the construction need to pre-wired. Normally pre-wire cable in under construction building are easy, but for those decorated house, it’s a big pain. This is a big flaw for hardwired alarm system, that’s the reason why majority people are choosing wireless alarm systems.
Majority of hardwired alarm systems are not suitable for DIY
Different from those plug-n-play wireless alarm systems, the setup and installation for hardwired alarm system requires user with some basic electronic knowledge, and some experience. If you want to DIY your hardwired alarm system, you have to know get fully understand the installation manual. Please note that majority of alarm manufacturers don’t provide step by step installation manual for end-users.
In the end, different types of alarm systems with its unique advantages and disadvantages. If you don't want just choose between hardwired alarm systems or wireless alarm systems, you can use the hybrid alarm system. Now most of security companies are offering hybrid alarm systems contain wireless and hardwired zones. These hybrid alarm systems provide the best advantages of both hardwired alarm system and wireless alarm system. They not only provide highest secure and reliable performance, but also offering flexibility for setup and installation. More over, nowadays the wireless alarm systems and hardwired alarm systems can use the same methods for alarm transmission, such as telephone line, GSM cellular, VOIP, Internet, VHF...etc, so that we have not discussed for these in this article.
