Linear AP-5 Wireless Kit - Linear AP-5 Long Range (500') Wireless Receiver (318 MHz) & Two Linear ACT31B Block Coded 1 Channel Key Ring Transmitters

Very fast shipping. No issues with vendor. Liked them packaging the transmitters with the AP-5 unit.The AP-5 is what they say it is. So nothing special there. The addition of the two extra transmitters was nice. We figure they are cheaper than buying separately. It had everything in it (cable, antenna, screws, etc.) - none of what we needed for a replacement unit, however nice to have for future maintenance. We use this in a development for car entry to open the gate. It is an add-on to the gate controller and was easy to hook up. We only use on feature (open the gate) and don't use all the other features provided in the device. We had to replace the device because ants nested inside it and it would not respond to the keypad for programming new transmitters. It did allow existing programmed transmitters to be used to open the gate. It MIGHT have also caused the gates to remain open and not allowed them to close (we will see if that problem is now fixed).There is one thing we learned that we really dislike about this device design. While they talk about 1 million codes, etc. (believing it is save from unauthorized entry), a transmitter can be cloned and used to gain entry. For example with newer car garage door openers, they can clone the transmitter and then the transmitter is no longer used - just the car button. This is a standard cyber attack vector. The other issue is that there is no logging of transmitters, so you can't tell who entered over a period of time or attempted to enter.In general, lots of capabilities and simple to use. Would recommend.
