Uninterrupted surveillance! UL-certified 24V4A desktop power adapter, a stable power supply solution specifically for CCTV cameras.
A residential security camera suddenly went offline late at night, only to be discovered it was a power overload. A shop's surveillance footage frequently displayed distorted images, only to be discovered to be due to power supply ripple interference. An outdoor camera was struck by lightning, burning out the power supply and causing a blind spot. The root cause of CCTV camera "failure" is that ordinary power supplies can't handle the "24/7 full load, strong interference, and multiple environments" security requirements. Surveillance equipment demands far more stable power than ordinary appliances, and choosing the wrong power supply can leave a gap in your security defenses.
Traditional desktop power supplies frequently encounter problems when used with surveillance cameras: either the power rating is inflated (rated 4A but only 3A), failing to handle the peak startup current of the camera's infrared fill light; or the ripple exceeds 100mV, interfering with the video signal and causing image freezes. Furthermore, they lack lightning protection, making them highly susceptible to induced lightning strikes during thunderstorms. The UL-certified 24V4A CCTV desktop power adapter precisely matches the needs of surveillance scenarios—96W of full power, low ripple lightning protection, and 24/7 stable operation, keeping cameras online 24/7.
Why is it a reliable partner for surveillance? Four key security-grade advantages
1. UL 62368-1 Certified, a Security-Grade Safety Bottom Line
This product has rigorously passed 108 tests of the UL 62368-1 Information Technology Equipment Safety Standard and fully complies with North American security equipment approval requirements: leakage current ≤ 0.75mA (only 1/4 of the UL standard), eliminating the risk of live metal housings carrying electrical current. The housing is made of V-0 flame-retardant material, resisting 750°C flame exposure for 30 seconds without rekindling, making it suitable for enclosed low-voltage electrical enclosures. It also complies with China's CNCA-C08-01 mandatory power supply certification, ensuring safety acceptance for both North American and domestic security projects.
2. 24V/4A Full Output to Withstand Infrared Startup Peak
Utilizing a high-frequency switching power supply, it delivers a full 96W rated output power with a 24V voltage fluctuation of ≤±0.5V, making it perfectly compatible with mainstream 24V cameras such as the Hikvision DS-2CD3T46WD-I5 and Dahua DH-IPC-HFW5442M-I1. The power supply provides a 120% overload buffer to withstand the 2-3 times peak current (approximately 6A) drawn by the camera's nighttime infrared fill light. The device maintains a temperature of ≤55°C even after 10 hours of continuous full-load operation, completely eliminating startup tripping and late-night downtime.
3. Low Ripple and Lightning Protection, Zero Video Signal Interference
The voltage ripple is ≤50mV (far exceeding the ≤100mV requirement for security equipment) and has passed UL electromagnetic compatibility testing (radiation value ≤30dBμV/m), eliminating screen distortion and frame rate drops caused by power supply interference. A built-in 6kV surge protector protects against both direct and inductive lightning strikes (most surveillance camera lightning strikes are actually caused by inductive lightning). Combined with an 8mm insulation spacing between inputs and outputs, no additional lightning arrester is required for outdoor camera wiring.
4. 5.5x2.5mm Universal Connector, Compatible with Multiple Installation Scenarios
Equipped with the popular 5.5x2.5mm DC connector (positive inside, negative outside), this connector directly plugs into over 90% of 24V cameras: box cameras, dome cameras, and dome cameras can all be connected directly without the need for adapters (preventing intermittent power outages caused by poor contact). The connector features a 3μm-thick gold plating layer and a plug-in/plug-out lifespan exceeding 5,000 times, making it suitable for frequent installation and commissioning. The 100-240V wide input adapts to various power grids, and the included 1.8-meter UL-certified power cable provides flexible wiring from the power box to the camera.
Security scenario testing: Zero monitoring interruptions
Residential security: Four cameras with infrared fill lights in the underground garage shared two power supplies (each supporting two cameras). They operated 24/7 for 30 consecutive days without downtime. The voltage was stable when the infrared lights were on at night, and the surveillance footage was flicker-free.
Shop surveillance: After connecting the convenience store cameras to the power supply, the screen distortion caused by ripple interference completely disappeared. The latency for viewing the live footage remotely on a mobile phone was ≤0.3 seconds, meeting security video clarity requirements.
Outdoor scenario: The power supply was used with cameras on the factory wall. After a 6kV inductive lightning strike during a thunderstorm, the power supply automatically triggered surge protection, allowing the cameras to record normally without any burnout.
Cross-border project: For a security project exported to North America, the power supply's UL certification expedited customs clearance. Working with a Rockwell monitoring system, the voltage stability reached 0.1%, achieving first-pass customer acceptance.
Choosing the right surveillance power supply ensures a secure security line! This UL-certified 24V4A desktop power adapter not only meets the compliance requirements of domestic and international security projects, but also ensures round-the-clock camera operation with its sufficient power, anti-interference, and lightning protection features, ensuring "uninterrupted, uninterrupted, and uninterrupted" surveillance at every location.
