Good Afternoon,

I need to connect 3 magnetic and 2 motion sensors directly to a DVR system. I am trying to do it wirelessly.

There are a number of solutions out there but most of these connect back wirelessly to their own receivers and systems.

Can anyone point me in the direction of any solutions that TX/RX in 433Mhz and that can relay an alarm signal to standard alarm inputs on a DVR?

 

Have a look at..

It is a base to start from.

 

Here's a wireless pair, transmitter and receiver, 433 Mhz ..https://www.allelectronics.com/item/wma-1/wireless-motion-sensor-alert/1.html
Should be enough to get you started

Thanks, I have researched a couple of these solutions. What I am looking for has to have a bus for alarm out signals to a DVR.

Which gets a bit more complicated. I have found one solution, the Dakota Wireless 2500.

It's a bit pricey however.
