Why choose this 4K security camera system?
4K camera detail
View 4K video from all 16 cameras. The recorder supports 4K coax recording at up to 8 fps.
Night vision up to 130 feet
Infrared illumination provides black-and-white video in darkness. Color video needs sufficient available light.
Audio over coax
Audio operation depends on the supported camera format and recorder mode.
Reuse compatible coax wiring
Connect cameras over suitable coax cable using BNC connections. Camera power uses a separate power connection.
Digital zoom
Take a closer look at areas of interest in live video or recorded footage.
Indoor and outdoor cameras
Indoor/outdoor turret housing for indoor and outdoor installation. Protect cable connections from weather.
Local recording and free remote viewing
Store recordings on the DVR and use the included apps for remote viewing. Internet is required for remote access, but local recording works without it.
Motion detection and playback
Use supported motion detection, recording schedules, and playback tools to find events and review footage.

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 support audio with a compatible DVR mode. Contact our team to confirm your recording 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 16 included cameras use all 16 BNC inputs. Contact our team to plan additional coverage.
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.
