A small form factor HD-TVI DVR capable of recording up to 4 HD-TVI cameras @ 1080P. This TVI recorder is also compatible with HD-CVI & AHD cameras. This makes it a good recorder choice for retrofitting a small install where old analog cameras are present and need to be retained. All channels are capable of motion events and notifications. Two of the four channels can be set up with Line crossing and intrusion detection events(VCA/Smart events). It can also support one IP camera @ a max resolution of 4MP.
