How Do You Power a Wireless Security Camera?

Although wireless security cameras have the edge over conventional or hardwired systems, providing them with a constant power supply is still an issue. These cameras also need more energy to monitor your surrounding. But this aspect depends on how often the device records and if it supports continuous video recording.

Thankfully, there are five sure-fire ways to power your wireless security camera and expect optimal functioning.

  1. Rechargeable Batteries

Wireless security cameras use rechargeable batteries to power the system. Moreover, since they only start recording after detecting motion, you can expect the battery charge to last more than thirty days.

These cameras are also easy to install. Besides, anyone with the correct tools and procedures can mount them within ten minutes. Hence, you do not need to contact a professional for the job.

Furthermore, most battery-powered security cameras do not need a home server. Instead, they use local storage such as an SD card or cloud storage.

However, the main disadvantage of these cameras is the hassle involved when replacing the batteries. For instance, you must climb a ladder to remove the accessory, charge it, and reload it later.

In addition, consider a few aspects before going fully wireless. For example, depending on the camera type, features like night vision, temperatures, and firmware deplete the battery charge faster or slower.

  1. Power Over Ethernet (PoE)

This technology is the most recent and convenient in hardwiring IP cameras. It uses the ethernet port to transmit electrical power and eliminates needing a separate adapter and DC cable.

However, remember, PoE ports differ from standard ethernet ports. You can’t plug the PoE cable into any ethernet port and expect your camera to power up.

The input device, which in our case is the IP camera, needs an ethernet port that supports Power over Ethernet. Also, most older cameras do not support this technology. Hence, check the specifications before purchasing.

Check for a spot labeled ‘PoE in’ under the security camera’s ethernet port. Further, some newer devices offer DC and PoE options, whereas older ones with DC and Ethernet ports may not support them.

Sometimes, your wireless security camera does not accommodate PoE, but you still want to integrate it. Here, splitters and injectors are handy as they combine the data and power signal and split the power and data cables at the gadget’s end.

Furthermore, this strategy eliminates the need for a secondary power wite to the camera and works best in areas without close powerlines.

Also, consider the camera’s power requirement before setting up PoE. Cameras needing more than 30W do not support Power over Ethernet. They need a dedicated DC or AC connection.

  1. Solar Panel

Hooking a solar panel is an excellent way to avoid recharging your wireless security camera. Thankfully, more high-end security units offer optional solar panels to power the cameras without an electrical supply.

Solar panel-based cameras are also easy to install as they do not need any hard wiring. However, be extra careful when choosing a panel spot, depending on the time of day and location. Otherwise, they will not get enough sunlight to maintain the gadgets.

One drawback of this powering strategy is camera placement. Usually, poor camera and panel positioning compromise the system’s efficacy. In addition, you need a long cable to connect the two accessories.

  1. DC Power

This method is an alternative if PoE is impossible for your wired security camera. Besides, most static cameras supporting PoE have a dedicated DC port that needs 5V OR 12V.

Security cameras using DC power are easy to mount. All you require is a wall outlet to connect your DC adapter, and you’re set.

However, you may have difficulty finding a wall outlet in some scenarios, such as when placing security cameras outdoors. So, consider the troubleshooting techniques below.

  • Install a New Wall Outlet Near the Device: Wall outlets near security cameras are good practice. Hence, get a professional to do some electrical and construction work to set them up.
  • Use an Extension Cord: Although this solution is the easiest, it is not ideal for the long term. Moreover, you need long-run extension chords, and concealing them may be challenging.
  • Use a Power Supply Unit: This strategy best provides DC power to multiple cameras. But the process needs some wiring and electrical work. Also, pick on high-quality units and install them correctly to avoid electrical faults, such as short circuits.
  1. AC Power

Some high-capacity wireless security cameras need AC power instead of DC. Usually, they are larger Pan Tilt Zoom devices requiring direct 220V or 24V AC power.

Fortunately, the unit is easy to set up, with most of the cameras needing a dedicated adapter and 24V AC power provided by the manufacturer. These adapters have a small step-down transformer to lower the AC voltage from the circuit before distributing power to the device.

Alternatively, you can get cameras with no transformers in-between or adapters. They directly connect the cameras to your home’s wall socket or circuit and power up immediately.

Nevertheless, regardless of whether the devices use AC or DC power, you’ll have to dedicate one or more wall sockets for the unit to function. Or you’ll need an electrician to extend your ring circuits for camera integration.

How Long Do the Batteries Last In Wireless Security Cameras?

Batteries last in wireless security cameras from one month to over three years. However, this duration lengthens or shortens depending on the camera usage and battery type. For example, rechargeable batteries last the longest, with most enduring at least 500 charge cycles.

Even better, today, we have powerful dry cells, such as Lithium-ion batteries, that withhold charge for the longest time. But still, they will die out due to negligible or extreme usage.

So, let’s discuss some factors influencing how long batteries last in security cameras. This way, you’ll take the most suitable measures to have them operational for a longer duration. 

  1. Streaming Mode

Most wireless security cameras do not record continuously. Besides, they have an optimized setting that allows them to function under specific conditions. For instance, the device will only record after detecting movement or thermal activity in the monitored region.

Battery-powered cameras charge only five minutes daily. As such, you can expect them to last for three to six months. But remember, the battery life decreases significantly faster if you do not activate optimized settings.

  1. Battery Capacity

Most of your camera’s battery life depends on its charge capacity. So, check the device’s specifications if you doubt how much energy it holds. You’ll see a numeric value with an mAH label for easier identification.

Ampere-hour is the measure that calculates the charge stored in a battery. The higher the mAH, the better the battery performs. Therefore, go for a higher value when working with more energy-consuming cameras.

  1. Temperature

Batteries charge electronic devices through chemical reactions. Hence, extreme cold swiftly slows the reactions down, making the dry cells incapable of keeping up with the camera’s power demands.

Areas with temperatures below 32 degrees Fahrenheit drain the battery’s charge, which eventually decreases the battery’s life. As a result, camera maintenance increases as you’ll frequently have to replace the batteries.

  1. Internet Connection

Signal strengths to the system’s receiver affect the camera’s battery life. Moreover, the receiver should be near the device since it transmits data over the air. Thus, weaker connections increase the camera’s power demand. 

Also, Wi-Fi interference weakens internet connections. Ensure that there are no obstructions and interferences between the receiver and transmitter.

  1. Firmware

Wireless security cameras have firmware from the manufacturer prescribing how they should operate. Further, they go through continuous upgrades to fix system issues or bugs on time.

But these firmware upgrades decrease the camera’s battery life. They transmit more data and pressure the device, requiring more power.

  1. Night Vision

Cameras with infrared emitters work best in low-light areas. And they need to output more IR lights to give a clear picture. Hence, if the device is in a poorly-lit environment, it will wear out the dry cells more quickly.
