The Cheap Raspberry Pi Security Camera

One of the great things about the Raspberry Pi is the community that works to create really great projects. I have setup a Raspberry Pi B looking out my windows. It faces the front door so can see anyone coming down the street and toward the door. I had a couple cheap $2 webcams lying around so I set them up looking out the windows. The total cost of the entire setup is about $10, minus the cost of the Pi itself, I also think that the Pi is a little underpowered for the task as occasionally the thing will stop working after several weeks, the camera still records the video, but the web-interface has to be reloaded in order to get the thing working again.

Overall, I’d say that this project was ineffective for its purpose because unfortunately, the cameras would not record movement accurately enough, and sometimes would record several hours of minimal movement. An IP camera would likely be more cost-effective and better suited for the task, the Pi I used was simply underpowered to monitor two webcams and crashed after about 2 weeks of working continuously. Viewing the files showed that although it captured movement and video, some were corrupt, glitch or only captured about 3 usable frames. It did, however, show a good live view of what was going on outside the house, with about a 4-second delay.

Overall I would say that a Raspberry Pi as a webcam security camera on the cheap is not a good idea, the main contributing factor being that it was not able to keep the program running and often would save garbage to the SD card. If I were to do this again I would not use two for definite as it simply did not work effectively enough to actually increase security, It would often record trees moving for hours and sometimes one camera would freeze up entirely.

Sources of Finance

What are Sources of Finance

dollar symbol sources of finance

There are three different sources of finance, Short Term, Long Term and Medium Term. The most popular way of attaining funds for a business is through equity (money flowing into the business) with over 39% of businesses using this method, examples of this would be retained profit or capital from shares.

Short Term (30 days or less) Medium Term (less than 6 months) Long Term (6 months+)
Sale of assets, selling business assets, such as product stock or vehicles. Overdrafts Lease-Back, Selling company property, then leasing it back. similar to rent to own, however the business owned it previously, but sold it to use the cash. This is usually very extreme and would only happen when a company is becoming insolvent. Sometimes can be longer than 30 days. Sponsorship, sometimes sporting companies can sponsor businesses. Trade Credit, retrieving goods and delaying payment for up to 30 days, usually this is enough time to sell the finished product, so prevents bad cash flow. Debt Factoring, Selling debt to companies, for less than its worth, allowing them to chase up debtors. Can be instant Could be cheaper than perusing the debt. Could generate a bad reputation if they are harsh. Short Term Sources of finance usually are less than they are worth, and usually allow a business to continue trading and prevent insolvency. Family Loans, does usually not require payback for a long time. Returns can also be small. Donations Crowd Sourcing Government Grants Leasing Collateral. A Bank Loan Stocks and Shares Personal Finance Venture Capitalists Business Angels Generally they come to a business, rather than the other way around. Generally they do not inter-fear with the business. They may not want payback. Floatation requires $50,000 Mortgage Debentures/Bonds Very Long term Usually a significant amount of money Fixed rate of interest Reduces Collateral Interest is payable Companies may have invested interest Retained Profit You have to have money to make money. May cause insolvency Needs time to re-build prevents investment in other areas

Sources of Finance in IT

Some Sources of finance can be de-facto, because it is easier. examples would be the IT industry, it is easier to lease IT equipment because it can allow for no capital outlay, meaning that they do not have to pay in full to have the equipment, but can pay in instalments.

Peer-to-Peer Funding is also becoming increasingly popular, whereby companies borrow money from large businesses and cut out banks to save cost on interest.
