Buying CCTV and access control looks simple until you start, and then the quotes arrive and none of them compare. One vendor sells you cameras by the megapixel, another by the number of channels, a third throws in an app and a discount. Underneath the noise, a few things decide whether the system actually helps you when something goes wrong, or just records a blurry version of it. This guide covers what to look for, written for businesses rather than installers.
Start with what you need it to do
The first question is not which camera. It is what you need the system to achieve. Catching a number plate at a gate, reading faces at a entrance, watching a wide yard, and monitoring a till are four different jobs that need four different setups. A camera that is perfect for one is useless for another. Before you look at any quote, write down the specific things you need to see clearly and where. Everything else follows from that, and a vendor who does not ask you these questions is selling you boxes, not a solution.
Megapixels are not the whole story
Vendors love to quote camera resolution because it sounds like more is better. Resolution matters, but a high-megapixel camera pointed at the wrong angle, or struggling in low light, or fed by a recorder that throws away the detail, gives you footage that is useless the one time you need it. What matters as much as resolution is performance in poor light, because most incidents do not happen in bright daylight, the lens and field of view for the specific spot, and whether the recorder keeps footage long enough and at full quality. Ask to see real footage from a camera the vendor has installed, at night, before you believe any spec sheet.
IP systems, not old analog
Modern business surveillance runs on network cameras, called IP cameras, rather than the older analog kind. IP systems give you sharper images, let you view multiple sites from one place, and connect to the rest of your IT. They also need to be designed and secured properly, because a camera on your network is a computer on your network. A badly secured camera is a way into your business, which is the opposite of what you bought it for. This is why surveillance should be installed by people who understand networks, not just cameras.
Access control: more than a locked door
Access control decides who gets into which parts of your premises, using PIN codes, cards or biometrics like fingerprint and face. Done well, it does several useful things at once. It removes the problem of lost keys and former staff who still have them. It gives you a record of who entered where and when, which matters after an incident and during an audit. It can tie into time and attendance, so the same system that secures your doors also tracks working hours. The thing to get right is matching the method to the door. High-security areas justify biometrics; a store room may only need a card. Paying for the most expensive option everywhere is as wrong as securing nothing.
The part most vendors skip: the law
CCTV records people, and in Kenya that makes the footage personal data under the Data Protection Act, 2019. As the business running the cameras, you carry obligations: signage telling people they are being recorded, a real reason for collecting the footage, controlling who can access it, and keeping it only as long as you need it. Most installers will never mention this, because it is not their problem if you get it wrong. It is yours. A surveillance system that ignores the law is a liability sitting in your server room, and getting this right from the start costs nothing extra. It just takes a partner who knows it matters.
One system, not three
The cleanest setups treat cameras, access control and the network they run on as one design rather than three separate purchases bolted together later. When they are integrated, your security operates as a whole: a door event can be tied to camera footage, everything is managed from one place, and there is one team responsible when something needs fixing. We built exactly this kind of integrated system for OYA Micro Credit’s head office, where cameras, biometric access and the network were delivered together rather than by three vendors who never met.
The test of a security system is not how it looks on the wall. It is whether the footage is clear and findable the one morning you actually need it.
If you are planning CCTV, access control or both, we design and install integrated systems that produce usable footage, respect the law, and connect safely to your network. Have a look at our systems integration page for the full picture, or talk to us about your site and what you need it to see.
