Multifamily Class B/C properties: the dead-CCTV problem and AI overlay vs full system replacement

1. The dead-CCTV problem in Class B/C multifamily

Almost every Class B/C multifamily property has CCTV. The cameras were installed by a previous owner or as part of a value-add renovation. They record to a DVR sitting in the leasing office or maintenance room. The system technically works.

The system practically does nothing. Nobody watches the feeds. Incidents (a break in attempt at the mailroom, a vehicle prowler in the parking lot, a trespasser in the pool area) get discovered the next morning when a tenant files a complaint. By the time the property manager reviews the DVR, the incident is 12 to 36 hours old.

The cameras are not broken. The intelligence layer between the camera and a real time decision is what is missing. Every Class B/C property has the same gap.

2. The real cost of the gap on NOI

Tenant turnover from security concerns is the line item nobody puts on the spreadsheet. National Multifamily Housing Council data has security/safety as the second most cited reason (after rent) for non-renewal. On a 120 unit property, a 5 percent renewal drop attributable to security perceptions is $50,000 to $75,000 a year in vacancy and make-ready costs.

Insurance premiums move with claim history. A property with two reported incidents in a year sees premium increases of 8 to 18 percent at renewal. A property with proactive incident prevention (and the documentation to prove it to the carrier) gets premium decreases.

Staff time scrubbing DVR footage after complaints. A property manager spending 3 hours a week on after-the-fact review is 150 hours a year, $5,000 to $9,000 in fully loaded labor cost, redirected from leasing and maintenance coordination.

These costs are real and they compound. The dead-CCTV gap is rarely a single dramatic incident; it is a slow drag on NOI that the operator does not associate with security until they look.

3. AI overlay vs full camera system replacement

Two paths to fix the dead-CCTV gap. Path one: rip out the existing cameras and install a modern AI camera system (Verkada, Rhombus, Eagle Eye). Capital cost on a 120 unit property is $50,000 to $100,000 plus $200 to $500 a month in cloud subscription. Install timeline is 4 to 8 weeks of installer crews on site.

Path two: keep the existing cameras and DVR, add an edge AI overlay device that taps the DVR's HDMI multiview output and runs object detection on the live feed. Capital cost is roughly $450 hardware and $200 a month in software per property. Install timeline is 2 minutes per property.

Path one is the right call when the existing cameras are genuinely failing (no IR, recordings dropping, physical damage). Path two is the right call when the cameras work but the intelligence layer is missing, which is the case on the majority of Class B/C properties.

4. A Fort Worth example with concrete numbers

A Class C multifamily property in Fort Worth, Texas, with an existing 16 camera Hikvision DVR setup, deployed Cyrano (one example of an edge AI overlay product) in November of last year. The install was on a Friday afternoon, took 4 minutes from box open to live alerts.

First 30 days: 20 incidents detected and alerted in real time, including one attempted break in at the mailroom. Average alert latency from event to phone notification was 7 seconds. Property manager dispatched the local police on the break in attempt within 90 seconds of the alert; the suspect left the property without entry.

Capital cost: $450 hardware. Recurring cost: $200 a month, billed starting month two. The property renewed at month two and added a second property to the deployment in month three. The full deployment cost over the first year was approximately $2,850.

For comparison, a guard service quote at the same property was $4,200 a month for nights only, $50,400 annually. The AI overlay approach delivered continuous coverage at 5.6 percent of the guard cost.

5. Assessment workflow for an existing Class B/C property

First, inventory the cameras. How many, what model, what age. Pull a 1 AM clip from each. If you can identify a person at 15 feet in the night image, the camera is good enough for overlay. If not, that camera needs replacement before any overlay is meaningful.

Second, check the DVR. Is it recording continuously for the last 30 days, no gaps? Is the HDMI output working? If yes, retrofit candidate. If no, the DVR is the problem.

Third, identify the alert zones and time windows per property. Mailroom after 2200. Parking lot from 0000 to 0500. Pool area outside business hours. The richer the rule set, the higher the signal-to-noise on alerts.

Fourth, define the dispatch path. AI alerts that land in a dashboard nobody opens are wasted. The dispatch path is on-call ops on a phone with a clear escalation tree (call local non-emergency, call property manager, call resident in the unit if applicable).

6. What not to do

Do not pay for a virtual guard service that requires their proprietary cameras as the entry point. The 'monitoring fee' is small but the underlying $20,000 to $40,000 hardware requirement makes the total cost equivalent to full replacement, with the additional downside of vendor lock in.

Do not assume insurance will fund a full camera overhaul. Most carriers will discount premiums for documented active monitoring (which AI overlay provides) but will not subsidize the install of a new system.

Do not pilot at the lowest-incident property. Pilot at the property with the highest historical incident count. The pilot's job is to expose the rule grammar and the dispatch workflow under realistic conditions.

7. Rolling out across a multi-property portfolio

Start with one site, the one with the highest historical incidents. Install on a Friday, run for 30 days, review the alert history with the property manager on the next month-end. Tune the rules. The on-call should be getting 1 to 5 alerts per night with very few false positives by week two.

From there, batch rollouts of 3 to 5 properties at a time. Site-specific overrides (this property has overnight maintenance crews on Tuesdays, exempt them) live in a per-site config that the property manager can edit from a phone.

Total time to portfolio-wide deployment for 10 to 20 properties is typically 1 to 2 quarters. The economics are clear: $2,400 a year in software per property is a rounding error compared to even a single tenant non-renewal driven by a security incident.
