Originally I had just as a remote camera using the app and that worked perfectly but I wanted the capability to record so I ordered the Hikvision 4 port NVR and 4mp EXIR Turret  from JT Wholesaler. This is a great camera. Superb quality, easy set up.Daytime quality is brilliant - very high resolution, good WDR and crisp images.Night time is good,I would say the 30m EXIR range is accurate I will be purchasing another of these cameras for the rear of the property . I have found Jamil's support nothing but most friendly and helpful and would highly recommend him.
