Perioperative leaders who want cameras and AI to run their operating rooms better often compare Aimbient and Apella. Both put sensors in the room, record when each case starts and ends without a nurse typing it in, and predict how long cases will run. Aimbient, formerly Surgical Safety Technologies, grew out of the OR Black Box, which records video, audio, and device data so surgical teams can review a case afterward. Apella, based in San Francisco, built its product around surgical volume: it writes case events back to the EHR in real time and plans schedules and staffing from them.
Large and academic health systems that want recorded surgery for safety review and teaching as well as OR efficiency
Staff and legal teams have to accept audio and video recording in the room, and getting that buy-in is its weakest score
Hospitals that want to fit more surgical cases into the operating rooms and staff they have
It has a shorter research record and less safety and teaching review than recording platforms built for that job
| Axis | Aimbient | Apella |
|---|---|---|
| What the room captures | Stronger Video, audio, and device data in operating rooms, cath labs, endoscopy suites, labor and delivery, and trauma bays. |
Camera video read by computer vision, which recognizes up to 14 events in each surgical case. |
| Fitting more cases into the day | Similar Reports up to a 34.8 percent cut in room idle time and up to 23 percent better case-length predictions than EHR estimates. |
Similar Reports an average 5 percent rise in surgical volume at hospitals using it, and its Horizon product predicts room use before the day starts. |
| Safety review and teaching | Stronger Built for it: teams review recorded cases the way a sports team reviews game tape, and the platform also supports trauma resuscitation review. |
Focused on operations: case times, schedules, and staffing. |
| Published research | Stronger Research using the platform appears in more than 100 peer-reviewed publications. |
Publishes customer results, such as its surgical volume figure. |
| Scale | Similar Live in 450 procedure rooms across North America and Europe. |
Similar Supported 500,000 surgical cases, with more than 200 operating rooms at Houston Methodist alone. |
| Getting it live | Scores 6.4, because each room needs recording hardware and staff have to accept audio and video capture. | Stronger Scores 7.2, with cameras and EHR write-back as the main install work. |
| Knowing what you will pay | Similar Quoted per room plus hardware and installation, with no public price list. |
Similar Quoted per room plus hardware and installation, with no public price list. |
“We saw the technology's impact on our clinical and operation systems during our initial 36-room pilot and have now scaled the technology enterprise-wide.”

Aimbient is for an academic or large health system that wants one recording platform for OR efficiency, safety review, surgical teaching, and trauma review, and whose surgeons and nurses will accept audio and video in the room. Apella is for a hospital whose main goal is more cases through the same rooms, and that wants case times written to the EHR and a schedule built on them.
Walk away from both if your staff or lawyers will not allow cameras in operating rooms. Walk away from Aimbient if you only want scheduling help and have no plan to use recordings for review. Walk away from Apella if safety and teaching review is the reason you are buying.
