Altronix ALTV244 4-Output 24VAC CCTV Power Supply
The Altronix ALTV244 is a wall-mounted 24VAC power supply engineered for small to medium CCTV and access control installations where distributed, fault-isolated power distribution is non-negotiable. Each of the four outputs carries individual fusing — meaning if one camera or access control device draws excessive current or fails short, that single circuit trips without taking down the other three. This isolation strategy is critical in multi-device deployments where a single bad device shouldn't cascade into a site-wide outage.
Key Features
- Four Independent 24VAC Outputs with Individual Fusing: Each output is independently fused, so a fault on one line doesn't disable the others. In a typical warehouse or retail CCTV system with four camera runs, a shorted cable on one run stays isolated — the other three keep rolling. That's the difference between a localized troubleshooting call and a complete security blackout.
- Wall-Mount Enclosure: Compact form factor fits inside utility closets, network cabinets, or surface-mounted on a wall near your main security rack. No floor or shelf space consumed.
- 24VAC Nominal Output: Standard 24VAC is the workhorse voltage for legacy and mid-range CCTV cameras, access control solenoids, and door locks. The ALTV244 supplies power at this voltage without requiring step-down conversion.
- Fused Circuit Protection: Each output terminates in a fuse holder, so you can replace a blown fuse without swapping the entire power supply. Standard replacement fuses are inexpensive and stocked everywhere — no proprietary parts.
- Lifetime Limited Warranty: Covers manufacturing defects for the life of the unit. On a passive component like a power supply, this reflects confidence in component selection and build quality.
- Multiple Device Support: Four simultaneous power feeds support up to four independent 24VAC devices (cameras, readers, strikes, relays) or can be ganged in pairs for higher-draw applications — flexibility depends on your device power budgets.
Integration & Compatibility
The ALTV244 plays well in analog CCTV ecosystems and hybrid IP/analog installations where legacy 24VAC devices coexist with newer PoE-powered IP cameras. It connects upstream to a standard 110–240VAC mains circuit and distributes 24VAC downline to cameras, pan-tilt-zoom motors, access control readers, door strikes, or any other 24VAC load. If you're integrating access control and CCTV power in one cabinet, the ALTV244 handles the CCTV side cleanly, leaving your main access control panel to manage its own distribution.
No special configuration or software required — it's a passive distribution device. Install it, wire the inputs and outputs, and monitor for fuse continuity. It works in any CCTV power infrastructure architecture.
When to Choose a Different Model
If you need more than four outputs, look to higher-capacity Altronix power distribution models in the same family. If your devices are already PoE-powered (IP cameras, IP-based access readers), you don't need the ALTV244 — route those through a managed PoE switch instead. If you require 12VDC instead of 24VAC, Altronix offers 12VDC alternatives; check the catalog for voltage options matching your device specs.
Deployment Context
The ALTV244 is well-suited to warehouse, retail, or small office installations where you're powering four or fewer 24VAC-compatible cameras and access control devices from a single distribution point. It's also a practical choice for remote locations (parking lots, perimeter gates) where you want to centralize power and fault isolation in one compact unit. Its fused architecture means you can troubleshoot a failed device without a full power cycle — swap the fuse, restore service.
Frequently Asked Questions
Q: What's the maximum current per output on the ALTV244?
A: Each output is independently fused. The fuse rating determines maximum per-output current — confirm your fuse specification in the product documentation or consult the datasheet for exact amperage per channel.
Q: Can I stack or parallel multiple ALTV244 units for more outputs?
A: Yes, you can install multiple units in the same cabinet, each drawing from the same 110–240VAC input, to expand total 24VAC output capacity. Wire each unit's input in parallel to your mains breaker or circuit, then distribute the four outputs from each unit to separate device groups.
Q: Is the ALTV244 suitable for outdoor installations?
A: The ALTV244 is a wall-mount enclosure designed for indoor or sheltered installations. If you need outdoor power distribution, look for IP66-rated or NEMA 4X outdoor-rated power supplies in the Altronix lineup.
Q: How long is the input power cord?
A: Verify cord length and connector type in the product documentation. Typical wall-mount power supplies ship with 6–10 ft mains cords, but always confirm before installation.
Q: Can the ALTV244 power PoE IP cameras?
A: No. The ALTV244 outputs 24VAC, which is incompatible with PoE (802.3af/at/bt over Cat6). Use this supply only for 24VAC-rated devices. PoE cameras require a PoE switch or injector on the network side.
Q: What's covered under the lifetime limited warranty?
A: Manufacturing defects in materials and workmanship are covered for the life of the unit. Consumables like fuses, normal wear, and user-caused damage are typically excluded — review the formal warranty document for full terms.

The ALTV244 is one of those unglamorous but indispensable pieces of infrastructure that keeps a distributed CCTV system standing when things go wrong. Individual fusing on each of the four 24VAC outputs means you're not replacing a whole power supply when one camera line shorts — you're swapping a three-cent fuse and getting back to work. That's the engineering trade-off that matters in field deployments.
Technical Highlights:
- Four Independent Fused Outputs: Each output terminates in its own fuse holder, delivering fault isolation at the circuit level. A shorted device or cable on one output won't trip the other three, keeping your site at 75% power instead of zero.
- 24VAC Nominal Supply Voltage: Standard voltage for mid-range and legacy CCTV cameras, pan-tilt-zoom motors, door strikes, and access control readers. No voltage conversion required downstream; wire directly to device terminals.
- Wall-Mount Form Factor: Compact enclosure fits inside standard 19-inch racks, network cabinets, or mounts surface-mount on interior walls. Saves shelf and floor space in confined equipment rooms.
Deployment Considerations:
- Confirm the fuse amperage rating matches your per-output device load before installation. If a camera and its associated access reader pull 3A combined, make sure each output fuse is rated for at least 3A (usually 4–5A nominal) to avoid nuisance trips on startup inrush current.
- The ALTV244 outputs 24VAC only — incompatible with PoE IP cameras or 12VDC-only devices. Verify all downstream devices are 24VAC-rated before wiring. Mixing voltage domains in one cabinet is fine (PoE cameras on a switch, 24VAC devices on the ALTV244), but each power source is independent.
The ALTV244 belongs in any mid-sized analog CCTV installation, warehouse perimeter setup, or hybrid IP/analog deployment where 24VAC devices are a permanent part of the design. Its fused architecture and wall-mount footprint make it the standard choice for fault-tolerant power distribution in spaces where you can't afford a complete outage because one device failed.
