A:AnswerThe lights are motion activated if you set it up that way. You can also use the phone app to manually activate the lights and the audible siren for each camera.
A:AnswerLorex has a 6GB HD that can be purchased. You can call Lorex at 1-888-425-6739 and give them your DVR model number and they will tell you the max capacity your specific DVR can handle.
A:AnswerYou can attach an external HDD. You can also subscribe to Lorex cloud service and have all your data online. If your DVR gets stolen you may still access the videos online.
A:AnswerYes they should work fine with the siamese rg59 cables. I would just watch your distance because your signal will become weaker the further you push it.
A:AnswerThe picture is very clear. The lights and siren can be turned off and on but the light is not very bright and the siren is not very loud. You can manually turn the lights and siren on from the mobile app. You can hear the siren when outside but not in the house. Very happy with the system and extremely easy to use. Pictures and mobile app is a bonus.
A:AnswerYes, you can setup an external IP address to view the footage. You can also setup a free account with Lorex and they will give you a url to visit to view your footage. The free version is for a couple days. The subscription levels can get you months of cloud storage.
You can use either the iPhone app or android app. I like this app since I can setup live notifications when motion is detected.
A:AnswerYes it can be used, but you will only be able to view the cameras from the monitor it is connected to via the hdmi cable from the dvr to your monitor.
A:AnswerNot sure if Best Buy will install, but you could certainly give them a call. As far as working with existing cameras, I was able to swap out my Swann DVR with this one and still use the old Swann cameras with it. As long as your cameras have a BNC-type connector, you should be okay.
A:AnswerThank you for submitting your question about this product. Unfortunately this product doesn't have built-in PIR's for the cameras.

A:AnswerThank you for your question about this product. These are fixed lens cameras and unfortunately do not do optical zoom like a pan tilt zoom camera.
