Never underestimate the significance of power supplies; they are the linchpin of stability for the entire surveillance system. It's truly about service and profit, something you cannot overlook. Today, we're revisiting the hazards to drive home one point: power supplies, though diminutive, have far-reaching implications for livelihoods. This insight is a must, and it's time to unveil the lesser-known aspects.

Why this ongoing emphasis on power supplies? Because in today's fiercely competitive security market, price wars have taken center stage as the primary means of competition. Unfortunately, unethical vendors resort to shortcuts, using counterfeit products to deceive consumers. This situation is also rampant in the surveillance camera power supply market. Two common culprits of substandard surveillance camera power supplies include recycling discarded electronic components and cutting corners on materials. The perils of these inferior supplies are manifold:

**1. Misleading Power Ratings**

This is the most prevalent phenomenon. Presently, many surveillance camera power supplies are labeled as 2A, yet their actual output might be as low as 1A or even lower. Some of these subpar power supplies experience significant power output decay over time due to the use of substandard or salvaged components.

Impact on Cameras: The repercussions for cameras include image jitter, absence of color or image, and poor night vision. In severe cases, cameras might fail to initiate, especially when infrared lights are activated at night. To determine the actual output value, one can assess the camera's loading situation and measure the voltage and current at the power interface.

**2. Insufficient Protection Measures**

Numerous subpar surveillance camera power supplies lack standard design features, such as overload and overheat protection mechanisms, and some even omit fuse protection.

Negative Consequences: This oversight could lead to camera burnouts or, in extreme cases, the power supply emitting smoke or causing fires.

**3. Inadequate Filtering, Image Interference**

Currently, the market offers inexpensively priced or unreasonably priced surveillance camera power supplies with circuit boards that generally lack common-mode inductors or filters.

Effects on Monitoring: The suboptimal effects on monitoring quality include ripple interference in the video feed. In low-light conditions like nighttime, these ripple interferences are especially pronounced.

**4. Substandard Input and Output Cables**

Subpar power supplies often use thin input and output cables, sometimes even employing inferior materials like aluminum-clad steel.

Detrimental Effects: Over time, these cables can result in inadequate power output. Cable sheaths might crack, especially in winter, and cable fractures can occur, disrupting the normal operation of surveillance cameras.

**5. Use of Inferior Plastic Casings**

The external casing of a power supply plays a pivotal role in safeguarding against physical damage and electrical hazards. Some unscrupulous manufacturers opt for cheap and inferior plastic casings that might discolor or crack over extended use, particularly in outdoor environments.

Hazards: Water ingress could lead to mild damage or, in severe cases, cause power supply failure, camera damage, or even electrical hazards.

Inferior power supplies harbor various unnecessary risks and potential failures. Some of these may not exhibit obvious issues initially but can develop numerous faults after extended use, causing the aforementioned harms to surveillance systems and unnecessary financial or reputational losses for purchasers. Despite some unethical vendors offering warranties or replacement services, their responsibility only extends to the power supply itself, excluding secondary economic losses due to these subpar components.

In light of this, it's crucial for buyers to scrutinize surveillance camera power supplies. Opt for quality over price, and thoroughly evaluate the circuit design of the chosen power supply. Brands like OHWOAI provide reliable solutions that prioritize quality and trustworthiness over low prices. In the end, investing in a dependable power supply safeguards the entire surveillance ecosystem.
