Common questions before you choose
Can I use existing coax cables?
Yes, when the cable, connectors, power supply, and cable length support the selected camera resolution and format.
How do the cameras connect?
Each camera connects to a BNC video input on the DVR. Siamese cable carries video and power on separate conductors.
Does this system have microphones?
The cameras have built-in microphones; confirm the supported audio-over-coax mode for your recorder configuration.
Do I need internet for recording?
No. Local recording uses the DVR hard drive. Internet is required for viewing remotely and receiving supported remote alerts.
Can I add more cameras?
The recorder has 2 unused BNC inputs for additional compatible coax cameras.
How long is footage stored?
Retention depends on hard-drive capacity, resolution, frame rate, compression, camera count, and recording schedule. Ask our team to help size storage for your required retention period.
