I received my orders very quickly. Could not fault the service.The installation guide for the cameras was easy to follow and the installation was however tedious as I had to do it myself. Drilling through cavity walls and passing the cable from one side of the wall to the other side proved to be difficult. Installing the cable elsewhere was easy. Setting up the camera to link withthe mobile app took quite a while as I had wait for quite long long time to speak with someone from Yale. After three or four phone calls the problem was solved. The Yale technical team were very helpful and very patient too.

The product meets my requirements,and was relatively straightforward to install,given my poor DIY skills.The manual that comes with it,though could be more informative,as I had to discover for myself how the zoom facility worked,and how easy is it too upgrade the hard drive,plus can I upgrade the cameras,but overall I am very pleased with the product.
