Wireless and digital technology powers today’s world – and commercial security systems are no different. When you trust Guardian Security to provide you with wireless security system monitoring, your business can benefit from around the clock security protection without the need for a landline phone.

AES Wireless Radio

AES is the premiere wireless transmission product in our industry. It offers the most reliable system, the fastest transmission speeds and can perform the task while saving you money.

Guardian’s private AES radio network is the largest in Washington and our coverage extends further than any other AES network in Washington.

Does your business use dedicated telephone lines to monitor the fire alarm system? If so, cut the phone cord and the phone bill and have Guardian’s trained professionals provide you with our radio monitoring which requires NO phone lines.

GSM Signal Transmission

How does a wireless alarm signal from your commercial site reach our central station? In short, the signal is transmitted via a cellular signal to a computer network that automatically decodes it. The entire process takes only seconds – and our highly trained operators take over from there, communicating clearly with you or your employees to deploy the necessary help to your location.

Reliable Monitoring For Education, to Healthcare, to Large Multi Site Facilities

Wireless monitoring is ideal for large commercial and industrial sites, including those with multiple buildings. At our central station, the operator receiving the signal should have all the information they need to send help to your place of business, whether it’s local law enforcement, the fire department, or medical responders.
