What are the internet service and bandwidth requirements for Alarm.com video devices?

Alarm.com video devices have network requirements and recommendations that, when met, provide an optimal experience to the user. The requirements and recommendations include recommended types of internet connections, router compatibility, bandwidth, and Wi-Fi signal strength requirements.

Internet service and bandwidth requirements vary by video device model, video device audio integration, and whether or not a Stream Video Recorder (SVR) is in use.

Internet connection type compatibility

Alarm.com video devices need an indefinite, always-on internet connection to function reliably. Some internet connections are incompatible due to restrictions they impose on bandwidth usage.

Internet type Compatibility
Fiber Recommended
Cable/broadband Recommended
DSL/ADSL Supported
Fixed Cellular Broadband Supported*
Fixed Satellite (via Low-Earth Orbit satellites) Supported*
Other fixed wireless Not supported
Traditional Satellite (via High-Earth Orbit satellites) Not supported
Mobile Cellular Hotspot or Aircard Not supported
Dial-up Not supported
Point-to-Point Not supported
Point-to-Multipoint Not supported

*While fixed cellular and satellite internet services are supported, they may experience intermittent outages at a higher rate than broadband alternatives. Performance depends on service coverage and varies by location

  • Always follow the cellular or satellite internet service provider best practices to ensure proper setup.
  • Unlimited data plans are recommended to avoid data overage charges.
  • Performance can be limited by the equipment provided by the internet service provider. Equipment provided may not support networking features such as multicast or bridge mode that enable certain video camera features and reliability.
  • Onboard Recording is recommended on compatible cameras for uninterrupted local recording during network outages.

Router compatibility

Alarm.com wireless cameras are compatible with most wireless routers. The quality of a router can affect the performance of the video devices as well as the rest of the network. Some routers may also need firmware upgrades to perform reliably.

A router broadcasting a secured Wi-Fi network with a unique SSID and strong password is recommended. Open networks or networks with a third-party portal to log in are not recommended.

For dual-band routers, verify that the 2.4 GHz and 5 GHz bands have separate SSIDs.

Note: The instructions for separating wireless bands differ based on the router model. Please refer to the manufacturer’s guide for more information.

Bandwidth requirements

Alarm.com video devices only use bandwidth when the user is streaming live video or SVR recorded footage, or when the device is uploading recorded video clips.

Alarm.com video devices primarily use upload speed, as opposed to download speed. Typically, Alarm.com requires an indefinite broadband connection of at least 0.5 Mbps of dedicated upload speed per video device. Keep in mind that 1080p streaming, doorbell cameras, Two-Way Audio, and SVR integration all require additional bandwidth.

Note: Dedicated upload speed refers to bandwidth only used by the video devices, so other connected devices (e.g., computers, smartphones, gaming consoles, etc.) require additional bandwidth on the internet connection.

Minimum bandwidth for residential video devices

The requirements listed on this page are based on a single user viewing one video device at a time.

The following limits describe where the audio and video streams start to become choppy under ideal environmental conditions (i.e., the Wi-Fi signal strength is strong and not blocked by walls or other objects).

Video device Required bandwidth
'20/'21 0.25 Mbps — Standard Resolution & Quality
'22 series 1.5 Mbps — Standard Resolution & Quality 0.5 Mbps — Reduced Resolution & Quality
ADC-V523/523X 2 Mbps — Any Resolution & Quality
ADC-V723/723X 2 Mbps — High Resolution & Quality 1.5 Mbps — Standard and Reduced Resolution & Quality
ADC-V515 2.5 Mbps — High Resolution & Quality 2 Mbps — Standard Resolution & Quality 1.5 Mbps — Reduced Resolution & Quality
ADC-V724/724X 2 Mbps — Any Resolution & Quality
ADC-VS123 Up to 2 Mbps depending on the connected camera

Minimum bandwidth for residential video devices using Two-Way Audio

Camera model Required bandwidth
ADC-V521IR 1.5 Mbps — Highest Setting 0.75 Mbps — Reduced Setting
ADC-V522IR and ADC-V622 2 Mbps — Highest Setting 1 Mbps — Reduced Setting
ADC-V523/523X 2 Mbps — Any Resolution & Quality
ADC-V515 2 Mbps — Standard Resolution & Quality 1.5 Mbps — Reduced Resolution & Quality
ADC-V724/724X 2 Mbps — Any Resolution & Quality
SkyBell Doorbell Camera (ADC-VDB101/102/105/106/105x/106x) 2 Mbps — Standard Resolution & Quality
Alarm.com Video Doorbell (ADC-VDB750) 2.5 Mbps — Standard Resolution & Quality
Alarm.com Video Doorbell (ADC-VDB770) 2.5 Mbps — Standard Resolution & Quality
Alarm.com Wireless Video Doorbell (ADC-VDB780B) 2.5 Mbps — Standard Resolution & Quality

Recommended bandwidth for an SVR

When using a Stream Video Recorder (SVR), it is recommended to meet the same minimum bandwidth requirements as the video camera live stream it is recording.

For playback speeds higher than normal speed, the bandwidth requirements increase with the playback speed

Example : To play back four ADC-VC726s remotely at normal speed, the user’s upload speed should be at least 6 Mbps. If the playback speed is 2X, the user’s upload speed should be at least 12 Mbps.

For more information about the bandwidth requirements of SVRs to stream remote playback, see below:

Additional signal strength information

The materials the signal passes through and the physical location of the video device affect the signal strength. If there are walls or any obstructions, the wireless range is decreased. Verify the signal strength meets the minimum recommendation to help video devices operate properly.

Note: Building materials like brick, plaster, concrete, stucco, and metal construction materials have the potential to cause signal interference, and could affect the signal strength and quality.

While a camera can still function below the recommended signal strength rating, having a signal strength below the recommended minimum can reduce the overall performance of live video. The affected video devices may also experience unexpected behavior with the camera’s functionality. Wi-Fi extenders can help improve wireless signal strength.

Troubleshoot bandwidth

If your upload bandwidth is lower than recommended, the cameras may still work but the live view may look jumpy since the frame rate is reduced as a result of the upload bandwidth limitation. To determine how many video devices an internet connection can support, perform a web-based speed test with a tool such as speedtest.net or the like.

If the internet bandwidth is too low, contact your internet service provider to find out how to increase their upload bandwidth.
