The Recorder
Many customers have an investment in older coaxial style cabling or otherwise wish to support a mixture of analog, analog HD and TVI cameras. For these customers Q-See have the Q-See QTH94 and QTH98 recorders. With support for either 4 or 8 2Megapixel HD cameras with PIR (Passive Infrared Cameras) these recorders have a long future.
The Passive Infrared Cameras (PiR) that work with the QTH94/8 DVRs are ideal for home environments with pets and other non-human triggers of motion detection. The PiR works with video motion detection to determine if the cause of the motion matches a human infrared signature reducing false positives, increasing recording storage times and notifying home owners only when its required.
The Cameras
The QTH98-4FT-1-AU bundle comes with 4 High Definition Passive InfraRed QH8222B-AU bullet cameras. If you desire more simply add additional cameras which are available separately up to a total of eight.
