Outdoor Security Alarm Systems If you want to buy and install an outdoor security alarm system, you will need to fist chose whether you are going to use hard wired or wireless equipment. Wireless is always the first option, but it does cost more. However, wireless alarm detectors require a lot less labour, and will save you money on installation. A lot of people don't trust wireless units these days, but we have found that the wireless detectors from Paradox have proven to be very reliable. The Roboguard Wireless Outdoor Beams are very stable too, however it has come to light that people can use a 433 MHz remote to jam the signals going from the Roboguard Beams to the Roboguard HQ. I do believe that there is an anti jam alert unit now available to help solve this problem. I have come to like the wireless systems nowadays as you can move them around very easily, where if it was hard wired, you can’t. Paradox offers 2 types of PIR’s, the DG85 Passive and the NV780 Butterfly. Both of these are available in wireless, but they will only communicate to a Paradox Alarm Panel that has a transceiver on it. Paradox DG85 PIR covers an area of 90-110 degrees 12-15 meters out (like a V coverage). The Paradox DG85 PIR also comes with an extra lens called the Pet Ally Lens. With this lens on, the passive becomes pet friendly, with the unit been installed about 1.1m high off the ground. The advantage of a PIR is that it covers an area, so people cannot crawl under the detection area. However, the down side to most PIR’s is that if a person cloaks themselves (using wet suits and boards etc), they can go through the detected area and not trigger the alarm panel. This can be solved using point to point beams, which we will talk about just now. The Paradox NV780 Butterfly PIR is used on the surface of your wall, and covers a 3-5 degree angle area to the right and left 12 meters out. These 12 meters can be shortened. The Paradox NV780 is great to cover your windows and entry points into the house or building, but does not cover any area in front of it. It is then best recommended that a Paradox DG85 is used with the NV780 Butterfly for best coverage and protection. Point to point beams come in different sizes etc but they all serve one purpose, transmit a beam from one side to the other (called the receiver). You can get different height beams, 2 beam, 4 beam, 6 beam and a 10 beam. The point to point beams then come in different distances, 30m, 40m, 60m, 80m, 100m and 160m been the more popular ones. These point to point beams are best used when you want to cover your windows or entry points into the house or building. But, because of the pricing, most people buy these beams and put them in their yard to “protect” it. But what they don’t understand is that anyone can crawl under the beam or go over it. So unless you are using it with a Paradox DG85 PIR, don’t install them to cover an outdoor yard or area. So, to sum up Outdoor Security Alarm Systems, it is best to use 2 types of detectors together, like the DG85 PIR and point to points. It will cost more, but will be more secure. Pointless spending thousands of Rands and you are not well protected. And one last thing on passive detectors, always have them mounted away from the house/building, facing backwards to the house/building. This will eliminate blind spots on the house/building.
